Koyuki's refusal to play along is what makes every delusion land, he's the brick wall that turns Kabuto's bit into actual comedy instead of just noise. The show knows the joke isn't that Kabuto is crazy; it's that Koyuki can't escape him no matter how hard he resists, and watching him slowly stop trying is the whole thing. By episode six you're not laughing at the punchlines anymore, you're laughing because these two have already won against each other.

Seri Koyuki wants nothing more than an ordinary high school life. That plan falls apart because of his classmate Kabuto Hanadori, who lives in a world of his own delusions. Kabuto imagines himself as a knight on a quest and insists that taking off his eyepatch will unleash a darker alter ego he calls Michael Offenbarung Dunkelheit. In Kabuto's version of events, the two are reincarnated companions from a distant past, which leaves Seri cast as the loyal Gestöber and stuck as the straight man to Kabuto's antics. Seri is set on not letting Kabuto push him around, but that proves harder than he hopes, and the fantasies often land him in embarrassing situations. Another classmate, Utsugi Tsukimiya, adds to the trouble with an uncanny knack for reading minds that slowly wrecks Seri's social standing. Adapted from a shoujo manga by Aki Arata, the result is a slice-of-life school comedy built on Seri's attempts to keep his distance from the chaos around him.
