History
Jin was a result of the Z.E.T. Project by the Amagi Corporation to create the perfect being to fight and destroy the escaped Players. He was however released by Gorou Kanzaki, who wanted nothing more for Jin than to grow up as a normal human. So he took Jin and ran away, becoming homeless in the process. After the death of his 'grandfather', Kanzaki, Jin stayed with Akemi Kawakami until he witnessed her 'death' under the hands of the Amagi Corp., in an effort to retrieve their creation. Although he at first refuses to use his powers, he later accepts his role when he discovered that the real Akemi was still alive safe and sound and for the sake of protecting innocent people. He has been living in a slum alone ever since, monitored closely by his creators, especially Mitsugai. He one day meets Hanako in the slum, and after saving her life, twice, has begun to have feelings for her, evident when he swears to protect her with all his might having sex with her soon afterwards. He even starts calling Hanako his girlfriend. After the Amagi mansion is destroyed, he goes into hiding along with Kouga and Konoha, Mei, Shimura, Hanae and the two black suits until Kouga has Seizou clear him of all charges.

While on a date with Hanako, he is attacked by the Sweeper, transforms in front of Hanako and blacks out, leading him to believe either he or the Sweeper killed her. Believing that, he thinks his life is now meaningless, and as soon as he gets the enhanced gum, he goes off on a suicide mission against EVOL. Jin is able to transform a creature known as "ZET", a mutant possessing superhuman abilities, but often mistaken for an other Player. The transformation is slow, though it may be accelerated due to extreme rage and conditions. He had lost this ability briefly, but regained it with the use of a special gum (Chapter 67). He later has a ceramic stake put in his heart by Seiji, thus allowing him to transform without the gum into "White" ZET(Chapter 102). It is later revealed by Hanae that the pendant his grandfather gave him has the ability to transform Jin into the "True ZET." The source of his strength appears to be the mysterious lump on his hand. After a Jin clone injected him with a formula that reacts badly with his gum, he has been having blackouts, not remembering what happened after a period of time. After his latest encounter with the Sweeper, he asks Hanae to create a stronger version of the gum, which transforms him into "White" ZET. He then learns of Seiji's plan to attack Amagi Corp., so he and the two black suits go to stop him. While there, they manage to kill the second Chameleon Player and a swarm of Corpse Riders (the latter with the help of Oyama), but he is overpowered by the Knight Player.
