About A Ninja and an Assassin Under One Roof

On the way home from school, Konoha Koga runs across Satoko Kusagakure, a ninja who fled her village. Rather than handing Satoko over to her pursuers, Konoha offers help and a shaky alliance that lands them under one roof. Satoko has left danger behind her but the chase follows, turning their apartment into a base of operations and a sanctuary from sudden threats. Between class bells and late night stakeouts the two form an uneasy partnership built on banter, improvisation, and a shared instinct for trouble. The ordinary rhythms of teen life collide with covert mayhem as their unlikely cohabitation attracts curious neighbors and the odd ally.

Produced as a 2025 animated comedy, the show is the creation of Fuyashi Tou and Hundred Burger. It presents an original concept voiced by Haruna Mikawa as Satoko and Kana Hanazawa as Konoha.

Early reception shows a mixed response with a 6.9 out of 10 from 16 votes. The show leans into the humor of clashing ninja lore with everyday high school life and looks at identity, loyalty, and the chaos that comes when two very different paths share a home.
