A naive stalker girl. The strongest man in Ikebukuro. A shut-in doctor with questionable credentials. A hedonistic informant...and the "headless rider" astride a pitch-black motorcycle!? As their paths cross, this eccentric cast weaves a twisted, cracked love story...

    A sorcerer cursed him with a reptile head and left him with no memory of his life before the transformation. Adding to the mystery, there's a specter of a man living inside him. But Caiman has one key advantage: he's now completely immune to magic. Along with his best friend, Nikaido, Caiman is hunting down sorcerers in the Hole, searching for the one who can undo his curse and killing the rest. But when En, the head Sorcerer, of the sorcerers, gets word of a lizard-man slaughtering sorcerers, he sends a crew of "cleaners" into the Hole, igniting a war between two worlds.

    Whether it’s slaughtering their enemies or obtaining wealth beyond measure, anything is possible with his powerful magic. But Seere’s latest summoner, Sakura Masuda, is unlike any he’s dealt with before. Namely, she’s only in fourth grade, and her wish is…for Seere to become her mama! Well, if that’s what she desires, then that’s what he will deliver—by becoming the greatest mama ever!
