Synopsis
Ninin ga Shinobuden centers on Kaede, an ordinary student, whose life takes an absurd turn when Shinobu, a ninja trainee, bursts onto the scene with a peculiar mission: to steal Kaede's underwear as part of her ninja exam.
This bizarre encounter sparks an unlikely friendship between the two girls. Kaede is drawn into Shinobu's chaotic world filled with unconventional ninja antics.
The story follows their adventures as Kaede navigates this new reality, encountering strange characters like Onsokumaru, a self-proclaimed ninja master who resembles a yellow Pac-Man. The anime promises a comedic blend of everyday school life and bizarre ninja training.
