Everyone knows Ichiro Kaku—brilliant, wise, multi-talented, and impossibly handsome. As the student council president with a 100% approval rating, and a genius girlfriend at his side, he’s the flawless star of the academy. But where there's light, there's a shadow... and that shadow is Jiro Kaku. Ichiro's younger brother exists solely to keep Ichiro perfect—yet no one even knows he exists. That all changes when Jiro encounters a mysterious talking severed head, and his ordinary invisibility collapses into chaos! A suspenseful and eccentric high school comedy unfolds as a zero-presence boy and a headstrong (and head-only!) girl team up in a bizarre, fast-paced partnership!
