Hoiho Hoihoiho

A life of constantly bumping your head... but that's it for today!

Kodama Konbukawa, a girl who awakens to superpowers after hitting her head hard, will
use this power to change everything! No, to change her school life! But even with her superpowers, things don't go as smoothly as she'd hoped, despite her life being full of failures... A new rising star in the world of everyday school gag manga has arrived, one that's somehow strange, somehow cute, and hilariously funny.
