To put it mildly, Shun Kaidou has a 'hero complex'. He refers to himself as 'Jet Black Wing's' because it is an alias he uses all the time. Shun believes the world is under attack and is under the control of a 'evil organisation' known as 'The Dark Reunion,' which oversees and controls everything. Despite these claims, he lacks powers, is not a superhero, and the Dark Reunion does not exist. In reality, he's a shy, awkward, creative, emotional, and cowardly young man looking to impress.
