Ninin ga Shinobuden

Kaede expects a quiet evening of studying, not a visit from an aspiring ninja who is hopelessly bad at sneaking. Shinobu's absurd examination assignment brings the two girls together, and her guileless enthusiasm soon wins Kaede over despite their disastrous introduction.

Friendship with Shinobu opens the door to a ninja community where parties and foolish schemes regularly take precedence over training. Presiding over it all is Onsokumaru, a small yellow creature whose claims to mastery far exceed his dignity. Between his outrageous ideas and Shinobu's earnest mistakes, Kaede discovers that common sense may be the rarest ninja skill of all.
