The bass player of Blast, Shin left his home and abandoned his original family name because of his dysfunctional family. He is in love with Trapnest's vocalist, Serizawa Reira, but because Trapnest is his band's rival, Shin had to moonlight as a male prostitute with Reira as one of his clients. He is an expert in mahjong, and is shown to become an actor in the future.
Great cosplay! And that earring... is really connected to his lip? I was told this is one of Shin's signature looks. Thanks to Miguel for sending this in!
