He has short dark blue hair, disheveled in different directions. His eyes are purple in color, also with huge circles under his eyes. Wears a choker with a crescent moon. He is a shy, quiet and pessimistic incubus. His task is to seduce girls sinful with lust, but it seems Shin himself is wildly embarrassed by this and tries to do without it. He has demonic abilities because he himself is an incubus demon! But with whom he also rarely uses them.
