Ninja to Koroshiya no Futarigurashi

From Seven Seas:
Satoko, a runaway ninja with zero street smarts, just wanted a quiet escape from her secretive village. Instead, she ends up crashing at the apartment of Konoha. A high school girl who moonlights as a lethal assassin.
What starts as an awkward roommate situation quickly spirals into a chaotic blend of dodging deadly pursuers, navigating high school drama, and figuring out who’s supposed to do the dishes. With razor-sharp comedy and nonstop hijinks, this odd couple is anything but ordinary.
