Shiromajo-san to no Henkyougurashi: Saikyou no Majo wa Nonbiri Kurashitai

Synopsis

After getting fired from his adventuring clan for his lack of combat ability, Tori wanders around and runs into the city's strongest adventurer—the White Witch! Since he has nowhere else to go, she hires Tori for his exceptional skill in...handling chores?! With his talent for cooking, cleaning, running errands, and other domestic odd jobs, he's the perfect fit for taking care of the extremely lazy White Witch and the garbage dump she calls her house. Follow Tori as he grapples with his new job as the caretaker of the beautiful White Witch and her three familiars. Perhaps once he has cleaned up the place, he can finally live a cozy life in the woods with his new employer! (Source: J-Novel Club)
