Kage kara Mamoru!

Behind Mamoru’s untidy hair and thick glasses hides a highly trained ninja. His family has guarded the neighboring Konnyaku household for generations, and protecting his absent-minded childhood friend Yuuna is now his responsibility.

Yuuna’s knack for stumbling into trouble keeps that secret duty far from quiet. Assassins, rival ninja and an increasingly crowded circle of acquaintances interrupt their school days, forcing Mamoru to save the girl without letting her discover the protector standing beside her.
