After a series of unfortunate events, young ninja Satoko has found herself sharing a house with the deadly assassin, Konoha. On the run from her village due to a misunderstanding, she's relying on Konoha's murderous skills to keep her safe from the ninjas seeking to kill her. But Konoha isn't the easiest to get along with and is only tolerating Satoko due to her excellent skills at cleaning up messes--both from Konoha's work and in her home. Somehow, these two will find harmony in their new life together while keeping ninja attackers at bay! So long as they can survive each other, that is.
