Sin is one of Guilty Gear's most memorable characters—a half-human, half-gear hybrid who's best known for traveling with Sol Badguy as a bounty hunter. He's the son of Ky Kiske and The Maiden of the Grove, though his relationship with his father is complicated; his love for his mother runs much deeper. He wears an eye patch over his right eye for reasons he's never really explained.
Growing up, Sol kept him on a chain and Sin never went anywhere without his stuffed animal, Chimaki. That rough childhood shaped who he is now—someone who's learned to trust Sol completely, seeing him as part father, part mentor, part friend. Over the years traveling together, Sin's overcome serious hardships and seems genuinely happy with how things are going.
Personality-wise, he's a bit of an odd fit in formal situations. Socially awkward and uncomfortable with order, he doesn't dwell on mistakes the way others do—which can come off as insensitive, but there's something refreshingly genuine about his simple, innocent approach to things. He's got an optimistic streak and isn't shy about his confidence. His appetite matters a lot to him, though there's apparently something else important he won't talk about.
Sin's also caught the attention of Valentine, the game's antagonist, because his Gear cells make him the literal key to opening The Cube—a pretty dangerous position to be in. Still, he keeps moving forward, working on overcoming his dislikes one by one and searching for new ways to describe the world around him.
