Gin is an assassin from "the mainland" who left following his twin brother Kin to a secluded island where they couldn't be disturbed. Gin, who had originally just been following Kin out of curiosity, felt kind of out of place in such a peaceful environment. He spent a while wandering around goofing out but was able to develop meaningful connections with other islanders, like his best friend Gavin. Gin married a like-minded playful butterfly, Murillo, and they had kids, and their kids had kids, and generally, Gin feels he did the right thing by quitting his assassin job and living out a peaceful life instead.
