Sukeban Deka II: Legend of the Iron Mask

Having lost Asamiya Saki, Sukeban Deka I, Kurayami has been looking for a successor, but he has been having trouble finding the perfect candidate. One day, his subordinate Nishiwaki brings him information about Godai Yoko, who has been brought up in Tosa wearing an iron helmet (Tekkamen). Yoko is taken to Tokyo and Tekkamen is removed by Nishiwaki but she refuses to join up with Kurayami's organization. He confines her in the basement of his mansion. Nishiwaki tells her that her eyes resemble her father's a lot. He seems to know about her father. He also tells her that she could open an opportunity in her life by being a Sukeban Deka. Kurayami offers her a condition to free her from confinement. She must defeat 10 armed men. He observes how strong she is and he is more impressed. She is freed, and she agrees to be the Sukeban Deka with the name Asamiya Saki and accepts a cherry-blossom-embossed yo-yo to learn the secret of her birth and her father's death.

Saki is sent to Kirinoha Gakuen, where a Kung-fu club is ruling the whole school. She tries to join the club Koryukai and shows how strong she is to the members. A girl, Fujitani Yuri approaches her saying that she wants to avenge her brother, Fujitani Jiro of the basketball club, who was beaten up by Koryukai. Saki tells her that she came to beat up the Koryukai. Yuri introduces Saki to Yajima Yukino, who is good at martial arts. Yukino doesn't like the Koryukai either, but she also doesn't feel friendly towards Saki. Yuri is attacked by Koryukai and Saki prepares to fight Koryukai. Knowing that, Yukino joins her. They defeat the members and are about to reach the leader, Hitori Reiko who barely escapes.

Saki then moves to Ryozan High where Nakamura Kyoko, also know as Bi-dama no Okyo, is the ruling sukeban and fairly peaceful. Due to a plot by Uehara of the journal club, Saki and Kyoko are tricked into fighting each other. Kyoko tries to attack Saki, but she doesn't respond though her power is superior to Kyoko's. "Why?" Kyoko asks and Saki replies, "Because I like you." They now become friends. There, Yukino approaches. She, longing to be with Saki, also moves to Ryozan Highschool. At night, Nishiwaki, Kurayami's agent who poses as a teacher in Ryozan High, is waiting for Saki and tells her, "Here's a new mission for you".

Saki's mission is to confront "Yaju-gumi" in Aoba Gakuen. Yuju-gumi are a group of three brutal boys who are about to come out from a juvenile jail. They are getting our earlier than planned because of a back-up power, and this power is the real enemy that Saki has to confront. Aoba Gakuen is in panic now because Yaju-gumi is coming back today at midnight. Saki offers help to the student union leader Kawamura who sent them to jail, and who is out of help now, and she gets bombed and injured. Though all the students and teachers escaped from the school, Saki remains and prepares to battle Yaju-gumi. Seeing that, Kawamura and others also come back to help her. She lures Yaju-gumi into the school and defeats them by using a trap she had set in the school. After the battle, Yukino and Kyoko meet her.

Kage-no-soto, the leader of a mysterious group Seirokai, thinks of a game. It is to gather elite students, make a cram school and "sell" them to a non-elite school that yearns to be a famous elite school. The price per student is more than 10,000,000 yen. Nishiwaki orders Saki to get in that elite cram school, Syuko-juku. The entrance exam is way too difficult and Saki barely gets in by being a "supplemental member". This school seems to have Hitori of Kung-fu Gakuen and Yajugumi in its background. Saki steps into the "student-recruiting" meeting with Yukino and Kyoko, and fights with the principal of the school Tamura. She then announces that she is Sukeban Deka to Tamura in front of Yukino and Kyoko. The two realize that Saki has been working for an organization and get very disillusioned. Saki leaves without a word.

Saki had Yukino and Kyoko know that she is a "deka". Saki wouldn't explain anything and the two just get more and more frustrated. Hayato, who used to be a wrestler and was converted into a killer by Kage-no-soto attacks her. Saki tries to strike back but her attacks have no effect on Hayato. Saki is in danger and then, Yukino and Kyoko jump in to save her. Saki now starts telling her story about her miserable past, her father's death, the helmet, frequent temptations of suicide and so on. Yukino and Kyoko get sympathetic and they get closer. They strike back at Hayato and defeat him. Kage-no-soto, observing the battle, somehow appreciates Saki's way of fighting. He, for some reason, has the same pendant that Saki has.....

A politician's car is attacked and the political fund in the car is robbed by a gang. A young man, Honda, steals that money from the group. He himself dies in a traffic accident. His brother, Yutaka, is in a orphanage which has some dark power as a background. Saki infiltrates the orphanage as a nun. Yutaka gets a message from his supposed-to-be dead brother Honda and heads to the meeting place. Saki follows him but another group is also following him - the group of robbers led by Samukawa. Surrounded by Samukawa and Saki, Honda, who pretended to be dead, tries to escape by taking his brother as a hostage.

Reifar has long been the sukeban of Yokohama, but another mysterious power is infiltrating in Yokohama. Reifar's members are consequently attacked, and Saki comes to Yokohama to help Reifar. Saki first doesn't like Yokohama because the sea is so filthy compared to her home town in Tosa. Reifar refuses Saki's help because she loves Yokohama so much. There is a pirate radio station monitoring their activity. The DJ of the station turns out to be Baron, the master of "stardust", whom Reifar trusts in. He is a member of Seirokai, which aims to rule Yokohama. Saki and Reifar fight together and they gradually get along with each other. Saki's yo-yo finally defeats Baron and she leaves Yokohama, beginning to be fond of it's sea.

Kokusho Sayuri, a member of Onyanko Club and a friend of Yukino, visits Saki. She, Saki, Yukino and Kyoko go to Harajuku together. In the chaos of Harajuku, Sayuri gets kidnapped. Without her, the live TV program "Yuyake-nyan-nyan" can't be on the air. Other Onyankos also go out to look for Sayuri. Saki gets information about Sayuri that although it's forbidden to have a close relationship with boys in the Onyanko Club - Sayuri has a boyfriend. The kidnapping is a plot that the boyfriend made, that by hiding her and making her skip the live TV show, he could make her quit Onyanko and he could see her as frequently as possible. Sayuri realizes how selfish the boyfriend is, and she breaks up with him. Saki is invited to the live recording studio and she performs in front of the camera the first time in her life.

Yukino hits a girl with her car and she learns that the girl, Machiko, was trying to escape with a man who used to be her Kendo teacher and a boyfriend, Takao. Yukino visits Takao who is waiting for Machiko and learns that he belongs to Seirokai, Saki's enemy. He is ordered to kill Machiko who made a trivial mistake, but he doesn't feel that's right and decided to run away. Seirokai, led by Kage-no-soto, consists entirely of students, and aims ultimately to make a success of a revolution by teenagers; the Wolf Revolution. Saki retrieves Machiko who was snatched away from the hospital, and prepares a Cesna plane for them to escape in. In leaving, Takao tells Saki to investigate Zeku, a rock-singer. Who is this Zeku?

Saki looks for Zeku, the rock-singer. He is a mysterious man who appears at the live concerts suddenly, sings and goes away immediately without having anybody know where. Even so, the fans would gather to his concerts. Saki manages to get a ticket to the concert and knows that Zaku plays the melody which Saki knows as the same melody that her music-box pendant has, which is her mother's keepsake. Zaku also turns out to be the "Kage-no-soto". Why, then, does he know the melody? Saki is so confused.

Okyo brings a baby to the school. She was handed the baby by a stranger on the street. He was being pursued by somebody. Also being an orphan, Saki feels compassionate about this matter and tries to find the baby's parents. Saki gets her next mission and it is to search for Itazaki, a specialist in military science. Meanwhile, Okyo and the baby disappear. In fact, Seirokai wants to utilize Itazaki's knowledge and to persuade him, they kidnapped his son, who happens to be the baby that Okyo is with. Threatened by Seirokai, Itazaki agrees to program a plan to kill Saki. According to the plan, Saki and Yukino are lured to a military laboratory and encounter various traps, which they barely escape. They succeed reuniting Itazaki and his son.

Saki, Yukino and Okyo come to Shirakaba Kogen Hotel Ski Resort. They come here because Yukino joined a students' chess tournament, and Saki has another purpose of investigating Seirokai's conspiracy related to the tournament. Saki gets to know a boy, Sano from Kinki District, who has a handicapped sister. Yukino battles with Sano at the first game and loses. Saki starts investigating the Seirokai's conspiracy, and she is attacked by a man, who later seems to run into Sano's room. In fact, Sano and his sister are orphans and they owe a lot to Kage-no-soto. Soto declared that he would promote the champion of the tournament to the executive of Seirokai and Sano's sister takes it seriously. Sano can't deny his sister's intention. Sano once tricked Saki but he later turns to her side. Soto considers it as betrayal and he kills Sano's sister. Saki defeats Soto's killers but Sano's sister will never come back...

Being frustrated by Saki's frequent interruption, Kage-no-soto, Shigaraki Kyoshiro sends a group of professionals - "Kyosya Shichinin-shu". A pretty girl, whose name is Takako, moves into Saki's school. Meanwhile, it seems like the people who are close to Saki are getting injured. According to Nishiwaki, this is a kind of hypnotism called "Kyosya-no-jutu". Saki cannot get close to anyone to avoid this jutu to be effective, and at last, even Nishiwaki is beaten and hospitalized. Saki becomes reclusive in order to save anyone that's close to her. One day, Yukino's driver, Miyamoto, comes to tell her that Yukino has been kidnapped....

Yukino is kidnapped. Saki still wouldn't let anybody get close to her. Getting frustrated, Okyo investigates the case, but, she also gets caught. Saki finally decides to strike back. Recalling the events, she realizes that only Takako, the newcomer, has not been affected. Saki confronts Takako and she shows her real form as the leader of Kyosya Shichinin-shu, Shishi. Saki confronts Kyosya Shichinin-shu and she barely wins. She retrieves Yukino, who was blinded by Kyosya Shichinin-shu. Seeing how matured she has become, Nishiwaki takes her to the tomb of his former best friend. The man, Saotome Shichiro, is Saki's real father...

Saki swears at her father's tomb that she will avenge him. She wants to know the story about her father but Nishiwaki wouldn't let her know, saying that she is still not mature enough. While practicing yo-yo, a blind old man approaches her and teaches her the trick of using two yo-yos. This man is Duke Nango, who actually once targeted Saki's father's life and also battled with Nishiwaki who was serving as a bodyguard of Saki's father, who was an archeologist. Saki confronts Nishiwaki to show how matured her skill is and throws a secret second yo-yo towards him. She thought it was a yo-yo which contains water, but it actually contains a poison given by Nango. Nishiwaki is beaten. Getting mad, Saki confronts Nango but she is still not an enemy of Nango. Nishiwaki then appears and beats Nango by a combination play with Saki. Nishiwaki mumbles, "he also would be a victim of that man......", does he mean Kyoshiro?

Saki infiltrates an all boys' school with Okyo as a purchase booth helper. Her true purpose is to get in contact with a boy, Osamu, who used to be an executive of Seirokai until a year ago. Osamu is plotting something using a remote control car with an automatic bomb. He is attacked by Seirokai and Saki saves him. He tells her the story about himself; he and his sister once belonged to Seirokai but his sister was killed by them because she learned that Soto wears a pacemaker in his heart. Osamu is targeting Soto's life. Saki wouldn't let Soto die yet, so she barely prevents the bomb-carrying radio-controlled car to crash into Soto. Soto leaves for the US to get his pacemaker adjusted.

The bancho of Kurokoma High established a Banchos' Union after being ordered by Michio of Seirokai. He has the banchos who resist him attacked by "Kaze", who is a killer with a lethal top "begoma". Saki and Okyo (disguised as boys in male-students' uniforms) infiltrate another all-boys school, Iioka High School, which is considered to be the next target. The bancho of Iioka High, Junji seems to be a coward. The day that Kurokoma High and Iioka High are supposed to fight, both parties seem reluctant to brawl and the battle seems quite dull (this scene nods to Akira Kurosawa's classic samurai film, "Yojimbo" starring Toshiro Mifune). Saki and Okyo offer a confrontation to Kaze, and the yo-yo/bi-dama combination barely wins over be-goma. Meanwhile, the battle between schools ends with Iioka's victory. Junji, finding out that Saki is really a girl, and feeling a little confident, asks Saki to be his girlfriend and she thrashes him.

A wild sukeban of coast side Chiba, Hirata Taiko is attacked by an underwater speargun. Incidentally, Saki and Okyo are visiting Yukino, who is hospitalized around this area, and are taken as the attackers just because they are the strange sukebans from outside. Okyo is taken as a hostage and Saki has to arrest the real attacker in order to free Okyo. Saki finds out that one of Taiko's subordinates is controlled by Seirokai and she attacks her. Seirokai has a plan to build a training center on this coast and feeling resentful toward Taiko, who would not sell the space for that. Taiko teams up with Saki and defeats Seirokai's surfer army. Okyo is saved and she and Saki leave for Tokyo with Yukino, who is freed from the hospital. Saki meets Taiko again and they promise to beat Seirokai together.

Saki has gone home to Tosa to have a break. Seirokai sends the next killer, Hayato, who uses acupuncture as his weapon. Not getting Saki, Hayato targets Okyo instead and she realizes that she remembers his face. She had a friend when she was little, who was very good at bi-dama, and she actually was taught how to handle bi-dama by him. His name was Takeshi and Hayato does resemble Takeshi. However, Hayato has lost his memory as Takeshi and keeps attacking Okyo. She tries to retrieve his memory in vain. She finally uses a lethal hit to his head and his memory finally comes back. He, however, goes back to Seirokai. Saki goes back to Tokyo.

Saki's yo-yo is out of order for some reason, and Saki goes out to a bank without her yo-yo. There, a group of Onyankos are performing a "chief of the bank for the day" and they get excited to have Saki as they have known her since the last incident. Then, a bank robber breaks in and takes Onyankos as hostages. Saki can't do anything because she has no yo-yo today. Yukino, learning about the robbery by one of the members of Onyanko-Club who overheard the plan and avoided joining the others, poses as a noodle-shop deliverer and hands Saki her yo-yo. Saki beats the robber and Onyankos are saved. They start worshiping Saki...

Saki's school basketball team is about to have a game with another school. The cheering group is lacking members and Saki decides to take part along with Okyo. The problem is that the team flag is too heavy for anybody to keep holding during the game, so Saki volunteers for that role. Meanwhile, the counterpart school is having the same problem. Learning that Saki is taking that role in Ryozan High, two hooligans, Tetsu and Koji volunteer because they once were rejected a date by Saki and the story stimulated their curiosity. On the day of the game, both sides get too excited and they start fighting. Saki, Tetsu & Koji settle this and the game is over peacefully.

Tetsu and Koji move into Ryozan High to be closer to Saki, by posing as girls. Okyo, though being a little jealous of Saki, decides to help these two. Saki goes for a date with Tetsu and Koji, but she is snatched by some boys who are resentful of the two and is held hostage. Tetsu or Koji can't fight them because Saki is held by them and they are beaten. While the two are unconscious, Saki, along with Okyo, defeat the hooligans. Tetsu and Koji, coming around, assume that they have beaten the hooligans. They go to get some ice cream for Saki, but while waiting for them, Saki gets the next mission. Can't Saki live as an ordinary girl? She goes back to her job without seeing the two anymore.

Saki and Okyo go to meet a man, Sekiguchi, who says that he escaped from Seirokai. At the moment he sees the two, he starts to run away and finally, he jumps from the top of a building. It seems like Saki drove him to suicide. Saki is feeling guilty of it and Kurayami Kikan ponders laying off Saki as the Sukeban Deka. Nishiwaki defends her and he is also laid off. Meanwhile, Tokunaga, a boy almost identical with Sekiguchi moves into Saki's school. Saki is in a total panic. She suspects that this might be a trick by Seirokai, but still wishes that Sekiguchi is alive in reality. She sees the ghost of Sekiguchi in her bedroom and she is into psychological trap and loses the will to fight. A trio of killers, Ranko, Horaru and Tsubaki who fight with ribbons attack her and she is getting thrashed...

Saki can't fight back the trio and Okyo's bi-dama doesn't work either. A car passes by and picks her up and she is barely saved. At night, the ghost (actually Tokunaga is plotting this) appears again. Saki is psychologically totally weakened and is tempted to follow Tokunaga's evil suggestion. He actually is a member of Seirokai. Nishiwaki scolds Saki for her weakness, he takes her to a seashore and trains her very strictly in Judo. This tough training helps Saki to retrieve herself and she gets cool again. Meanwhile, Yukino visits the late Sekiguchi and realizes that the photo shows a different man from the one they believe as Sekiguchi. In fact, Tokunaga posed as Sekiguchi and used his body to trick Saki. Tokunaga hopes that Saki, feeling guilty of Sekiguchi's death, would jump from the same site. Pretending that she is still deceived, Saki tricks Tokunaga and finally defeats him.

A girl with a mask has been attacking sukebans every night lately. Okyo is attacked by sukebans of Miyashita High and she defeats them. They say that the girl who attacked them the other night resembled Okyo. She encounters the girl and notices that she is identical with herself. One day, Okyo receives an invitation card to a very exclusive membership club from Shingyoji Rei, who seems to be the girl with mask. Okyo visits the club and Rei treats her nicely. She declares that sukebans are flakes and that is why she is attacking sukebans. Okyo feels angry about that but she has been drugged by some sleeping pills and is confined by Rei. Rei considers it a huge insult that a lowly sukeban like Okyo has the exact same face as she does. Rei and Okyo battle in an underground compartment and Okyo barely wins. Okyo wakes up and finds herself on the roof of Ryozan High building. Oyko is holding a letter. Saki asks "is that a love letter?" Saki tells her that she has been gone for several days. Was it a dream?

Yukino's eyes are close to full recovery but it's been delayed because Yukino fears the light for some reason. In fact, a man sneaks in her room every night and makes her fear the light to delay her recovery. Yukino doesn't know that. Yukino secretly loves an intern doctor, Ohmori. One day, Yukino is called out by Seirokai saying that they are keeping Ohmori as a hostage. Yukino goes and defeats the killers. At last, the final killer shows up ... it is Ohmori. He actually is an agent sent by Seirokai to kill Yukino, but he couldn't feel right to fight with a blind person. Moreover, he delayed her recovery to postpone their confrontation. Knowing his heart, Yukino asks him to withdraw from Seirokai and take the path of a doctor. Here, Yukino comes back.

A junior high sukeban trio, Mami, Noriko and Takako are called Mami of yo-yo, Non-ko of pistol and Dump Otaka. They challenge Saki for their reputation but Saki avoids an unnecessary fight. Saki gets another mission. She has to protect a biotechnologist, Shimomura. While she is on guard, the trio challenges her again and she has Shimomura snatched from her during the mess. Takako happens to know where he is confined and she offers Saki a condition. She tells Saki the location and in exchange, she requests Saki to confront the trio. Saki accepts and saves Shimomura. Knowing that her power is much greater than the trio's, Saki is still reluctant to confront the trio, but impressed by Mami's words, "without fighting with you, we can't see our future", Saki decides to confront them. Saki easily defeats them and is still not sure it was really the right thing.

The Soto of Seirokai is coming back from the US after getting an adjustment in his pacemaker. Seirokai is planning to proceed with the plan to take over Japan very seriously with Soto's return. Concerned, Saki approaches one of the candidates for membership, Ijuin Kaname of Kyorei Girls School. Saki obtains an ID card and a mask from her and infiltrates Seirokai as Kaname. However, getting suspicious about her, Ranko, Tsubaki and Hotaru are released to investigate this and they find the real Kaname. Saki's plot is revealed to the Soto. Having Kaname trapped as a hostage, Saki can't fight as much as she wants. There, Yukino and Okyo appear and help her escape. Saki follows Soto into an underground pathway. He and she confront each other and realize that they both are playing the same melody on their music boxes. She shouts "Who are you? What do you want with me?". He leaves without explaining anything.

He leaves without explaining anything.

Kage-no-soto calls another set of killers, Kurobane Gonin-shu. They had their father killed by Saki's father, Saotome Shichiro, in the past and this fight against Saki means vengeance for them. They hit the three's Hiko, the secret weak spot, without having them noticing it. Their whole body start losing mobility, their arms are already immobile. Meanwhile, Kage-no-soto is wondering why Saki has the same music-box pendant. he has the remote memory of his childhood and a girl repeatedly appears in the memory. Would it be Saki? He then has a phone call from "the old man of Kamakura". Soto seems to be obeying him with hostility. What does this man mean to soto? What is the Wolf Revolution by Seirokai? What is the secret of the pendant? Can the three escape from the curse of Kurobane?

To escape from Kurobane's curse, it's necessary to hit Ura-Hiko, sort of "anti-Hiko" but nobody has any idea where it would be. Saki takes the other two to Yukino's vacation house to hide from Kurobane until Nishiwaki finds out about Ura-Hiko. Meanwhile, finding about the story of Saki's past and Saotome, Saki's father, Soto orders Kurobane to hold off their attack on Saki for a while. For fear of Seirokai's destruction, Kurobane tries to kill Saki as quick as possible and find out where they are hiding. Saki pushes her almost immobile body and the other two and set traps around the house to repel Kurobane. Kurobane finally start attacking Saki and they do their best to resist. However, they can't move as they intend to, and Saki gets trapped in a trick which she herself set. Accidentally, a tree branch hits her Ura-Hiko and she gets freed from the curse. She frees Yukino and Okyo, too, and defeat Kurobane at last.

The Wolf Revolution has started. Soto, helped by the old man of Kamakura, suppresses the media. The old man learns that Saki actually is Saotome Shiori, through the information by Kikaibo. He gives orders to kill Saki because he thinks she is no longer necessary....what does he have to do with her? Soto tries to exploit Saki in order to manipulate Kudo Miki of Reishin Gakuen for Girls to take over Kansai area. Saki gets poisoned by Namera, a member of Nekome family. The poison takes over Saki's mind by high frequency radio-waves. Saki attacks Miki, being controlled by Namera. There, Kikaibo shows up and he saves Saki. He can't let Saki die yet till he learns how much she knows about the secret of Tekkamen.

Yukino and Okyo follows Saki to Kansai and are shocked to know that she attacked Miki. They promise to take care of her and start looking for Saki. Saki is still controlled by Namera and attacks the two. But her yo-yo power is not as effective as usual because of the poison and she is about to surrender them. Then Kikaibo shows up again and he takes Saki away. He gives Saki an antidote and makes her tell him the thoughts she holds in her mind. Listening to her, Kikaibo learns that Saki hardly knows anything and decides to free her alive. Miki, having witnessed the whole event, decides to be on her side. Saki gets back to herself and she defeats Namera.

The first victim of the Wolf Revolution happens to be Reifer, Saki's old friend in Yokohama. Saki decides to organize an anti-Seirokai group, Ryozan Rengo. However, the true purpose of the top of this evil conspiracy, the old man of Kamakura, is something different. He is looking for something that Saki's father Saotome Shichiro found and hid 12 years ago. The secret location seems like to be in her Takkamen. Kikaibo, ordered to snatch the Tekkamen, approaches Saki as if he were an old friend of hers. He tells her that her real name is Shiori makes her trust him. Nishiwaki then shows up and prevents Kikaibo from taking the Tekkamen. Kage-no-soto, who is actually Saki's old friend Kyoshiro learns about Tekkamen and starts to move on his own apart from the old man. Nishiwaki, concerned about Saki's mental instability, confines her to help she retrieve herself. The focus is on Saki's past and her Tekkamen now.

The battle between Seirokai and Ryozan Rengo is now at its peak. Ryozan Rengo presently has the advantage and Seirokai snatches Kudo Miki to threaten Ryozan Rengo. Saki sneaks out from her confinement to go and save Miki. Saki fights with three enemies to get Miki back. Saki's power is at its peak and she, with help of Yukino and Okyo, succeeds in saving Miki. However, the Tekkamen gets stolen in the chaotic battle. Kyoshiro now has a chance to defeat the old man of Kamakura, Shigaraki-ro. He orders Seirokai to quit the Wolf Revolution. To take over the nation, he doesn't need unnecessary battles. He can just defeat Shigaraki-ro and take over his power. However, in his heart still remains a bit of sympathy toward Saki. Having Tekkamen stolen, Saki is in deep grief.

Saki starts to wonder if Kyoshiro is her brother in reality. Kyoshiro is investigating the Tekkamen but can't find any clue. He learns that a man has been confined by Shigaraki-ro in the Kurobara-house where Saki was born. He thinks that this man will tell the secret to Saki and plots to have Saki get in the house. That, in fact, is what Shigaraki-ro plotted. Saki, along with Yukino and Okyo get into the house. Saki secretly hoped that her father was still alive and the man in the house would be him, but this man calls her, "Lady Shiori." Saki is disappointed. Saki, however, thinks that this man should know the secret and she tries to save him. There, a military troop comes and attacks her. Saki barely escapes with the help of Yukino and Okyo. Then Kyoshiro shows up and he calls the man Genjuro. Genjuro is also surprised to see him...

Kyoshiro captures Saki with Yukino, Okyo and Genjuro. Soto starts to recall her old days and remembers that Genjuro was a servant of the Saotomes. She can't remember one thing that if Kyoshiro is her brother and Genjuro tells her that he used to be a good friend. Saki feels too close to Kyoshiro and thinks that she can't fight him. Kyoshiro, however, says that he could kill Saki and threatens Genjuro to tell him the secret of Tekkamen. Being threatened, Genjuro tells the story which is quite shocking for Saki. Her mother used to be a spy who was sent to find the treasure of Kinura. However, she fell in love with Shichiro, Saki's father, and gave birth to Shiori. Fearing that Shigaraki-ro would kill off everyone who knew about the treasure once he obtained it, she enclosed the secret location in the Tekkamen and put it on her daughter. Then, the killers of Shigaraki attack them and Saki and Kyoshiro fight back together.

Saki is told that the pendant which Kyoshiro handed to her in the battle is a part of the clue to find out the treasure of Kinura. Saki meets Nishiwaki and he says it's time to tell her his story. He tells her that he put the Tekkamen on her by following Shichiro's words that he wanted Nishiwaki to do so after he died. Kyoshiro realizes that the clue to find out the secret location of the treasure is the melody of the music-box pendants, as Tekkamen responds to some kind of frequency. He also realizes that the embossed marks on the two pendants, once combined, make the school mark of Tenchi Gakuen, which is already out of service. The three go to Tenchi Gakuen and they meet two men, Tendoh and Chidoh, who are watching the treasure. They handed Saki a copper mirror and says the only way to get the treasure is by reflecting the Tekkamen on the mirror.

Tendoh and Chidoh also hand Saki a letter from Shichiro. It describes his sorrow to put Tekkamen on her and he wants Saki to defeat Shigaraki-ro on behalf of the people. Kyoshiro discovers that the treasure is in Ryozan High. Meanwhile, Shigaraki-ro judges that both Saki and Kyoshiro are no use now and sends killers. The two meet at Ryozan High. Saki retrieves the treasure and offers Kyoshiro to fight against Shigaraki-ro together. He refuses saying that he wants to take over the nation by himself. Then, the killers sent by Shigaraki-ro arrive and deliver a knife attack to Saki. Kyoshiro, trying to save Saki, intercepts the knife. In dying, he says that he wanted to see her in a different situation.

The treasure of Kinura, in reality, turns out to be a sake cup. The water filled in it gives eternal life to the person who drinks it. Shigaraki-ro wants immortality. To obtain the cup, Shigaraki-ro pressures Kurayami-shirei politically to lay off Saki as the Sukeban Deka. He sends a troop and the cup is taken. Saki is determined to get the cup back in order not to give immortality to Shiraraki-ro and goes to defeat him with Yukino and Okyo. Yukino and Okyo get beaten, and furthermore, Kurayami orders her to stop, but she wouldn't listen. Nishiwaki comes to help her pursue what she believes.

Saki infiltrates the mansion of Shigaraki-ro with Nishiwaki. There, his troop is waiting for them in ambush. Saki and Nishiwaki fight valiantly but the number of the soldiers is too much versus only two. Nishiwaki, while in the midst of battle, starts telling Saki why he is fighting with her like this. He used to love her mother Michiko and her family, and he has been regretting that he could not save her family 12 years ago. He, at least, wants to save Shiori, the only survivor of the family. Shigaraki plots to kill both at once and sends a soldier, Ranmaru, with a time bomb installed in his body. However, Ranmaru also wants them to defeat Shigaraki-ro and he blows himself up at a distance from the two. Saki and Nishiwaki are rushing toward Shigaraki-ro but Nishiwaki is beaten and Saki passes out. The lunar eclipse, the time that the cup is filled with the elixir of immortality, is getting very close. Shigaraki-ro is exhultant in the victory. Then, the chimes of the music box are heard. Saki bursts out from the pond at the very moment that Shigaraki-ro is about to sip the elixir. She, with whatever the power she has left, breaks the cup and falls back in the pond. Kurayami-shirei arrives and his gun puts an end to it all.
