Shun Kaidou - 海藤瞬

Shun is a young man who considers himself to be the "Jet-Black Wing", a lone hero fighting against the evil organization Dark Reunion. He also believes his powers stem from a dark being living within his arm. To his friends and peers, including [Saiki](https://anilist.co/character/90107/Saiki-Kusuo), he's simply an immature kid playing a game that only he understands.
