Kamen Rider Gaim

At the Free Performance Zone in the planned city of Zawame, the dance group Team Gaim are having a free-spirited dance when members of rival Team Baron demand the stage. Team Gaim's member Mai Takatsukasa accepts the challenge of Team Baron's Zack in settling their dispute with an Inves Game. However, with Peko helping his team cheat, Team Baron gets an advantage when Mai's Inves manifests in reality and runs amok. Luckily, a Team Gaim member named Kouta Kazuraba arrives and sends the monster back, but Team Baron wins by default. Upon meeting with Team Gaim's leader Yuya Sumii, Kouta learns of how the Inves Game is gaining popularity before he returns home to see his older sister Akira Kazuraba, asking her when he will be able to transform. The next day, Kouta gets a call from Yuya that he has found something interesting. When he gets to the meeting point, he finds Mai instead of Yuya, but both find a portal similar to the one used to summon Inves. They enter the portal and discover a forest full of strange fruit that when picked transform into Lockseeds. They soon discover the item Yuya was talking about, a strange belt that the Lockseeds can attach to. They leave the forest, but discover that they are being chased by an Inves that followed them out of the portal. Kouta decides to distract the White Tiger Inves long enough for Mai to escape and get help. Out of instinct, Kouta uses the Orange Lockseed on the belt and transforms to a samurai-like figure, using his new-found power to overwhelm the White Tiger Inves while quickly learning of his various new abilities. As they take their fight up a building, Kouta sees a mysterious girl resembling Mai who tells him that he is now bound by fate until he dyes the world in his colors. With the mysterious girl showing him how to use his belt, Kouta uses the Orange Charge attack to destroy the White Tiger Inves. After negating the transformation, Kouta is found by Mai just as he realizes he actually transformed.

After showing his sister that he can transform, though she is annoyed with his repeated changes, Kouta ponders how to use his new abilities. Unfortunately, Kouta ends up messing up while at his jobs and later finds a boy stuck on a tree before the child is saved by Team Baron's leader Kaito Kumon. Sometime later, Mai calls Kouta to inform him that Yuya is still missing. The two meet up and Kouta decides that they should ask Sid, the Lock Dealer, as to what has been happening. Sid informs the two that the belt that Kouta has used is called a Sengoku Driver and it bonds to the first person who wears it, and it is now Kouta's destiny to use it to help Team Gaim. In light of the events, Sid tries to give Mai a high class Lockseed. Later, Kouta gets a call that Team Baron is at Team Gaim's garage to issue a challenge for their Player Pass with Team Baron's Pine Lockseed and the western stage as the prize. Kouta heads to the garage and accepts the challenge, using his Ichigo Lockseed to summon the Deer Inves to defeat Kaito's three Inves. However, Peko decides to cheat, much to Kaito's dismay, knocking Kouta's Lockseed away from the battle area, causing the Deer Inves to manifest in reality. Kouta realizes that protecting people from the summoned Inves is the best way to use his power, and he transforms to fight the Deer Inves. However, the Inves ingests the Ichigo Lockseed and evolve into a higher form to overwhelm the orange-based samurai. When the Deer Inves prepares to attack Kaito, Kouta uses the Orange Sparking ability to protect his rival, but he asks Kaito for the Pine Lockseed. He uses the new Lockseed to Arms Change into Pine Arms, using the pineapple-shaped Pine Iron weapon to destroy the Deer Inves. Kaito is left speechless at what he has just witnessed, and elsewhere, at the Yggdrasill Corporation's headquarters, administrator Takatora Kureshima is informed of the appearance of the Armored Rider Gaim
