The popular manga series A Ninja and an Assassin Under One Roof (Japanese: Ninja to Koroshiya no Futarigurashi), penned by HundredBurger, is set to conclude with its seventh compiled volume. The announcement came from the sixth volume of the series, indicating the impending finale for the black comedy and slice-of-life narrative.
The Journey of Satoko and Konoha Nears Its End
A Ninja and an Assassin Under One Roof, also known as NinKoro, began its serialization in ASCII Media Works’ shōnen manga magazine Comic Dengeki Daioh “g” in February 2021. The series quickly garnered attention for its unique premise and comedic tone, revolving around an unlikely cohabitation between a runaway ninja and a high school assassin.
Plot Overview: A Deadly Domestic Duo
The story centers on Satoko Kusagakure, a naïve ninja who flees her village under unclear circumstances. Without money or connections, she finds herself in a precarious situation until she is rescued by Konoha Koga, a seemingly ordinary high school girl who secretly operates as a professional assassin. Their partnership forms out of necessity: Konoha offers Satoko shelter in exchange for the ninja’s unique ability to transform non-living objects into leaves, a skill proving incredibly useful for discreetly cleaning up after Konoha’s assassination jobs and tidying her messy apartment.
As the two navigate their dangerous yet domestic life, they face threats from ninjas dispatched by Satoko’s former village, rival assassins, and the everyday chaos of their unusual living arrangement. The manga explores themes of found family, comedic hijinks, and the challenges of maintaining a semblance of normalcy amidst deadly professions.
English Release and Anime Adaptation
Seven Seas Entertainment has licensed A Ninja and an Assassin Under One Roof for English publication, bringing the unique duo’s story to a broader audience. The first English volume was released on December 16, 2025.
The manga’s growing popularity also led to an anime television series adaptation, produced by Studio Shaft. The 12-episode anime aired from April to June 2025, further expanding the reach of HundredBurger’s creation. Crunchyroll streamed the anime as it aired.
The Anticipated Conclusion
While the sixth Japanese volume confirmed that the seventh will be the final installment, the precise release date for the concluding volume in Japan is currently anticipated.
