Jin serves as Takaya's right-hand man and the brains behind "Revenge Request." He's the group's tactical adviser, hacker, and demolitions expert—grenades and bombs are his weapons of choice in combat.
What makes Jin interesting is the tension between his zealous loyalty to Takaya and his rational streak. He genuinely believes SEES are hypocritical and don't deserve their power, but he's also the one who keeps Takaya grounded when he gets too reckless. Jin sees Takaya as a savior who pulled him out of darkness after the Kirijo Group's experiments, and that debt shapes everything he does.
Ironically, despite being fiercely anti-SEES, Jin becomes one of their biggest sources of intel—whether by accident or design remains unclear. He's the one who spills crucial details to the protagonist: the real story of Strega's origins, their connection to Nyx, and the fact that Shuji Ikutuski was never actually on their side.
In the end, Jin goes out in a blaze of glory. He detonates a grenade to hold back a massive shadow horde in Tartarus, giving SEES the time they need to push forward. It's a fitting exit for someone caught between conviction and conscience.
