Amazon Riders

In the five years since the fateful day, Operation Tlaloc takes care of a large number of escaped Amazons; during an Amazon hunt, Chihiro encounters Iyu, an Amazon-fighting girl.

Kurosaki's 4C squad and the returned Chihiro hunt Amazons together; Chihiro transforms for the first time to protect someone; Iyu dazzles Chihiro as she fights without feeling any emotion or pain.

Chihiro and Iyu engage in a fierce battle and Mizuki interferes; the former extermination squad bands together once again under Shido to put an end to what happened five years ago.

Wanting to help Iyu learn to live like a human being again, Chihiro runs away from 4C with her; Shido and his squad head out to investigate the water source used for the water dispensers and have a reunion with someone unexpected.

Mamoru, who turns up in front of Shido and his squad, bluntly presents them with the reality of being an Amazon, unable to live in peace; Mizuki, who was heading for a different water source, meets Haruka.

Chihiro wants to see Iyu smile, so he begins looking for the things she used to enjoy; the so-called Original is identified as the cause of everything.

Squad 4C takes extreme measures against Chihiro to find out more about his origin; Iyu heads toward the fun place that Chihiro told her about, where she encounters the one who wants to put an end to all Amazons.

Jin Takayama remains obsessed with killing every single Amazon; after his wounds heal and he regains consciousness, he takes notice of Nanaha, who had always been at his side.

Chihiro, confronted with the reality of being the Original, decides to sacrifice himself to save Iyu, who had been taken hostage; Haruka and Shido encounter a mysterious Amazon in Mamoru's hideout.

By Kurosaki's order, Iyu can once again hunt Chihiro; while on the run, Chihiro becomes incapable of suppressing his Amazon instincts; those around him are no longer moved by the youngster's desire to live.

Chihiro is no longer only targeted by 4C, but by Jin as well; unwilling to submit to his fate, Chihiro fights with Haruka.

Thinking about Chihiro finally begins moving Iyu's heart; Jin and the extermination squad have various painful experiences heading their way.

Haruka submits to Mizuki's judgement; Jin confronts Nanaha on his own; the extermination squad faces off with Mamoru; Chihiro and Iyu struggle to keep hold of their humanity in their little remaining time.
