Overview: A Ninja and an Assassin Under One Roof#
If you are looking for a blend of action-themed characters and cozy daily interactions, A Ninja and an Assassin Under One Roof (also known as Ninja to Koroshiya no Futarigurashi) is a title to keep on your radar. The story follows Satoko, a naive kunoichi who escapes her ninja village, and Konoha, a high school girl who happens to be an assassin. The two end up living together, leading to a lifestyle filled with both danger and excitement.
This series falls primarily into the comedy and slice of life genres, making it an ideal choice for viewers who enjoy character-driven humor and the “odd couple” living dynamic. You can watch the anime on Prime Video to see the chemistry between Satoko and Konoha for yourself.
Is the anime really finished?#
When deciding whether to commit to an anime, the biggest question is often whether the story reaches a satisfying conclusion.
For this series, the source material provides a clear endpoint. According to reports from December 2025, the A Ninja and an Assassin Under One Roof manga concludes in its 7th volume. Because the manga is relatively short, there is a strong possibility that the anime adaptation can cover the bulk of the narrative. However, to ensure you get the full, definitive ending and every detail of Satoko and Konoha’s journey, we recommend picking up the written source material.
You can buy the manga to see how the story wraps up.
Audience and Appeal#
Who is this anime for? If you enjoy seeing high-stakes characters (like ninjas and assassins) placed in mundane, domestic situations, this is the show for you. The appeal lies in the contrast between Satoko’s naivety and the dangerous world they both inhabit.
It is best suited for fans of:
- Slice of Life: For those who love the “living together” trope.
- Lighthearted Comedy: For those seeking a show that balances excitement with laughs.
