Rein Shun is the embarrassing, cringe kid who is delusional about his fantasies, believing he have a hidden power and created an imagery villian called 'The Jet-Black Wings' and Rein fights alongside the 'Dark reunion'. Rein is actually clumsy, childish and cowardly who acts strong. He have no friend but he doesn't care because he's too egotistical. Rein is a short, 16 male, half white half black hair, wears bandages with no injuries under and grey eyes. A weeb who can speak Japanese fluently.
