Shin is a slim man with short, light-colored hair that he wears parted with bangs hanging down his forehead.
He wears a black cape and a pair of baggy 3/4 pants, as well as a black bowler hat and pale sneakers. Like the other Eight Expendables, he sports a black plague mask.
Shin appears to be a very cynic man as a result of the fact that he could never find anyone worthy of his trust and friendship thanks to his Quirk. He states that emotions are unnecessary to carry out objectives, but it is unknown if he actually believes this or if it was just a way to demoralize Mirio Togata as he fought Overhaul.
Because Overhaul is the only truly sincere person he’s ever met, Shin is extremely devoted to him. Since he is granted knowledge about his boss's plans, Shin holds himself in high-esteem among the Eight Expendables, viewing himself as special and the only one of the group worthy of walking alongside Overhaul. Shin's loyalty to Overhaul is enough to make him follow his boss even after getting completely overwhelmed in battle.
Psychological Manipulation: As a former con artist, Shin has knowledge about confidence tricks, using those abilities in conjunction with his Quirk to psychologically dishearten victims.
- Handgun: Shin is armed with a simple handgun, which he uses as his main form of offense.
