Jin is Takaya's faithful right-hand man, acting as his tactical adviser and the webmaster of "revenge request". He uses hand grenades and other small bombs in battle, and is also a skilled computer hacker. He is "well-known" on the internet, according to Akihiko Sanada. Fuuka Yamagishi in particular recognizes the name Jin from her time online. Jin's most prominent trait is his loyalty to Takaya, to the degree of a zealot. Jin shows to be quite intelligent being the information gatherer of Strega and web author of the Revenge Request website. He is very adept at locating their victims. Although, despite his intelligence, Jin is shown to have a very aggressive disposition as well as sharing the same misanthropic views as Takaya, though he is more rational than him acting as a voice of reason to Takaya's more impulsive behavior. Jin dislikes SEES and appears very eager to be rid of them, since he believes that they are hypocrites who don't appreciate their own power.
