A Ninja and an Assassin Under One Roof

Main characters

• Satoko Kusagakure (草隠 郷子)
• [3]
• An escapee ninja from the hidden village somewhere in the mountains of rural Japan. She has poor martial arts skills, is a bit incompetent, and was often used to do menial tasks that other ninjas in the village considered beneath them. However, she learned how to clean, cook, and otherwise take care of others through her toil. She specializes in turning non-living people and objects alike into piles of leaves, making it easy to hide evidence and dead bodies.
• Konoha Koga (古賀　木葉)
• [3]
• A rookie assassin and high school student seeking to rise through the rankings. Incredibly skilled at assassination, she had trouble rising through the national assassin rankings as she often used points to take care of dead bodies and related chores rather than do them herself. After meeting Satoko, she finds herself slowly rising in rank, though she has trouble warming up to anyone besides herself.
• Marin Izutsumi (イズツミ マリン)
• A young mad scientist and rival assassin who designed Roboko to spy on Konoha and remove the competition, later becoming a reluctant friend of both the ninja and the assassin. She and Minato soon begin living in Konoha's house after their homes were accidentally destroyed by Satoko.
• Kuro (黒)
• The leader of the escapees from the ninja village who actually fled to be with her lover, Yuriko, in the civilian world. A very strong ninja in her own right, though she rarely shows off her skills, she does have the power to briefly hypnotize people and modify their memories. Kuro also enjoys gambling at local pachinko parlors, which frustrates her partner to no end.
• Yuriko (百合子)
• Kuro's lover willing to offer moral support to her and her friends, though she repeatedly tries to rein in Kuro's frivolous spending on pachinko and other unnecessary objects.

Other characters

• Roboko (ロボ子)
• A robotic duplicate of Satoko that was initially designed to spy on Konoha. However, Konoha soon got attached to Roboko, making Satoko jealous and eventually leading to her destruction. Marin later makes a smaller model, Roboko Mk-II, which retains Roboko's memories, followed by a third model, Mk-III, which more resembles the original model.
• Aoko Yoshida (吉田 碧子)
• Konoha's classmate who is unaware of her job as an assassin. Aoko's father was one of Konoha's victims, though Aoko is also unaware of this.
• Aoi Satou (佐藤　葵)
• Aoko's friend who ends up being Konoha's assassination target, albeit her status is unknown.
• Minato Izutsumi (イヅツミ ミナト)
• Marin's older sister, a crazed scientist with a sister complex who murdered their parents. She and Marin began living with Satoko and Konoha after their homes were turned into leaves.

Anime

In the Spring 2025 anime preview guide from Anime News Network, James Beckett said he knew he was going to love the series from the "first scene," while praising the comedic elements, and the "contrast between the lush production values and the deadpan editing," and promised that it would be "a keeper." Caitlin Moore said that while the series "is not going to be a top-shelf SHAFT title" it had "cute and simple" character designs which echo those in Miss Kobayashi's Dragon Maid and noted how the series threw you out of complacency while it played itself like "a yuri-tinged sitcom about a pair of opposites in violent professions." Richard Eisenbeis called the series a "light-hearted yuri rom-com" and also compared it to Miss Kobayashi's Dragon Maid, saying that the hidden feelings of the characters drew them closer, argued that Shaft had "really brought their A-game this time around" and concluded that enjoying the series depends on whether you like yuri and its style of humor. Rebecca Silverman was less positive, saying that the viewer might find it funny if they liked "clumsy ninjas" and grew weary of the dynamic between Konoha and Satoko, saying that the latter was "a combination of a walking disaster and terribly endearing." While she praised Haruna Mikawa, Satoko's voice actress, Silverman concluded that she could not come up with "any particularly strong feelings" about the series, which she called "perfectly adequate."[37]

Eisenbeis reviewed the first two episodes of the series for ANN, saying that while he thought it would a "light-hearted yuri", it was not this at all, with murder jokes, and laughs coming from the "burgeoning relationship between Konoha and Satoko." He also praised the "stunning visuals" and called the episodes "fantastic," and said he could not wait to watch more.[38] Cy Catwell reviewed the first episode for Anime Feminist, giving it warnings for blood and fan service, saying that comedy anime could "often be hit and miss," and said the comedy worked in some senses, but did not have the same charm as The Great Jahy Will Not Be Defeated!. They criticized the "leering shots" toward women in this episode, while noting that the "yuri vibes are strong" but said they were not sure they would watch past the first three episodes.[39]
