Zetman

The key to completing ZET is the pendant that Konoha has in her possession. Haitani and his men easily infiltrate the Amagi residence. Konoha wakes up and finds Jin standing in front of her. She hands him the pendant, not knowing he's actually a clone.

Kouga learns that Jin has been fighting by himself as ZET. Thrilled over meeting a true hero, Kouga calls him "ZETMAN" and declares he will fight alongside him. Jin and Kouga head for the lab to find out why Red ZET turned white.

ZET finally turns red and displays powers unlike anything seen before. With overwhelming strength, ZET dominates the fight against a Player. Meanwhile, Kouga is having a tough time fending off a Player in his first battle as Alphas.

Konoha is taken hostage and Jin is unable to do anything. Unlike before, he cannot become ZET by hurting himself and doesn't have his Activation Gum.

Kouga tries to become a superhero by creating a real-life Alphas. A mysterious man approaches him with a test to see if he's qualified to become one.

Two years have passed. Players are wreaking havoc in society, but humans are still unaware of their existence. People live in fear, and Mitsugai is unable to produce another ZET.

When Jin wakes up, he sees a monster holding the lifeless body of his foster mother, Akemi. An old man named Mitsugai is attempting to awaken ZET within Jin by using her. Mitsugai succeeds and ZET awakens...but he's still incomplete.

A few years have passed since Jin went missing. Kouga, still dreaming of becoming a real hero, is intent on catching a serial arsonist prowling the streets.

Jin Kanzaki is poor, but he lives a happy life with his grandfather. Together with his friends Kouga and Konoha, he helps out people for a fee. Meanwhile, the police are searching for a vicious serial killer.
