The comedy doesn't build a narrative, it just keeps finding new angles to make you laugh at the same absurd premise. Every episode is a riff on "ninja girl wants your underwear" played through a different joke structure, from slapstick to deadpan to outright surrealism. The art style matches that randomness, shifting just enough to keep you off-balance. This is what happens when you let comedians make an anime instead of asking them to serve a plot.
Kaede's quiet study session gets interrupted by Shinobu, a ninja trainee whose entrance exam requires her to steal Kaede's underwear. What starts as a ridiculous confrontation spirals into an unlikely friendship when Kaede discovers the chaotic world hiding beneath the surface of her ordinary life. Suddenly she's surrounded by ninjas who treat training like one long party, mysterious martial arts techniques that barely make sense, and Onsokumaru, a round yellow creature claiming supreme ninja authority while acting like he's perpetually on vacation. The show runs on pure absurdist humor, treating ninja mythology as a playground for jokes rather than anything resembling genuine action. Every episode throws something weirder at the wall, and the fun comes from watching how sincerely everyone commits to the stupidity. Kaede becomes the audience surrogate, constantly baffled by the logic of this world but increasingly unable to resist its ridiculous charm. If you want comedy that doesn't take itself seriously for even a second, that finds humor in the gap between anime ninja tropes and complete nonsense, this lands exactly where you need it.
