Ultraman Z has faced countless harsh battles. He now receives a message from Ultraman Zero. As Z arrives on planet Ialim, he is suddenly bathed in a mysterious light and changed into a new form! Why is he on planet Ialim, and what awaits him there?

Ultraman Z has arrived on planet Ialim. There, he looks back fondly at the achievements of his mentor, Ultraman Zero. But then, a new sphere of light appears! What is it, and why has it appeared in front of him?

Ultraman Z now has the New Generation Ultra Hero Cape, but to wear it, he must first understand the bond between the Ultra Heroes. There's a lot for Ediom to cover regarding the Ultra Heroes' history, but to start things off Z will first revisit and further understand the beginnings of himself.

Z wants to expand his understanding about the other Ultra Heroes, so Ediom presents him with Ultraman X's data. Ultraman X and Zero have a tight bond and have fought together. What will Z learn from their teamwork?

After seeing Ultraman X's armor, Ultraman Z becomes curious about the various armors worn by other New Generation Ultras. By exploring the armors' powers, what will Z learn about the Ultra Heroes themselves?

Ultraman Z gazes at the Ultra Z Riser that connects him with Haruki Natsukawa. He learns it's not the only item that forms bonds with Ultra Heroes, there are as many of them as there are heroes. Z also comes to understand the meaning of the bonds each item contains.

Beliarok, the phantasmic magic sword, suddenly appears before Ediom and Ultraman Z on Planet Ialim . With its arrival, Ediom learns how the sentient sword came to be. Earth was facing a desperate crisis. What a terrifying tale...

The sentient sword Beliarok doesn't let its wielder decide what it slices and pays no mind to whether they are on the side of light, or darkness. Ultraman Z looks back on Beliarok's exploits. What new knowledge will he gain?

Ediom had heard about Ultraman Trigger from Ignis. Seven years later, a new hero inherits the light Trigger had nurtured. His name is Ultraman Decker. When Trigger and Decker assemble, it is to stand against a great peril.

Ultraman Trigger and Ultraman Decker team up against an enemy. The consciousness hidden within it leads light and darkness to the next stage. When Z learns this, something begins to grow in his heart, giving him a deeper understanding of bonds.

Beliarok, the Phantasmic Magic Sword, is bored and bothers Z with its childish behavior. Ediom, unable to stand this sight, proposes examining data on other Ultra Heroes' weapons. Z learns the hidden intent that makes each Ultra swing their blades.

On his way to spar with Ultraman Blazar, Beliarok runs into Ultraman Zero. Zero refuses Beliarok's challenge to fight saying it would bring back bad memories of his fated nemesis and the battles he fought against him. However...

Beliarok demands to hear the rest of Ultraman Zero's battles, who obliges. Zero and his companions begin their search for the Shield of Baradhi so they can overpower the Belial Army. However, someone is waiting for them...a hot-headed space pirate who desires freedom.

Zero and his friends arrive on the Planet of Mirrors they learned of from Glenfire. There, they find a miserable sight. The noble Mirror Knight has fallen prey to Belial's darkness. Meanwhile, Belial's dark hand draws closer to Ultraman Zero...!

After rescuing Mirror Knight, Zero finally faces off against Kaiser Belial. However, Belial still has a trick up his sleeve, driving Zero into a corner. What new power will Zero gain? The final showdown against his fated nemesis begins!

Ultraman Geed appears before Beliarok and Zero. He tells them that his destiny was connected to the story between Zero and Belial. This sparks Beliarok's curiosity and he asks Geed to talk about his past battles. In response, Geed starts with something he seems to have overcome...

Beliarok appears before Z and Ediom once more and tells them of his encounter with Zero and Geed. Z recalls the fight against Gillvalis, where he and Geed first met.

Riku is suddenly kidnapped from STORAGE HQ. Haruki and the others rush to his rescue but a formidable enemy appears. Z and Geed are put in an impossible situation! What will happen to them? Plus, the hero shows up late?!

Looking back on heroes' past battles, Z questions his purpose. Seeing him like this, Ediom shows Z a fight that brought the New Generation Ultras together!

The New Generation Heroes head for Planet Tenebris to save Zero and Grigio, who are trapped there. But old, powerful enemies and the Darkness Copies back them into a corner. How will they break through?

The New Generation Heroes break out of a bad situation with the power of their bonds! However, another enemy from the past returns... In the midst of this fierce battle, Ultraman Zero powers up with a new form. At last, the final showdown begins!

Watching the Ultra Heroes' fights, Z seems to have found the meaning of Ultras' bonds. Ediom begins to reveal the answer. But what answer did Z find...?
