Koga Ryoichi

The innoncent ninja Shinobu, super-handsome-boy Otonomaru, and their merry band of friends are back! The official sequel to the legendary gag manga "Ninin ga Shinobuden" makes an unexpected return in the Reiwa Era! Enjoy the dazzling world of Ryoichi Koga!

Shinobu is the only girl that goes to the secret Ninja Academy, which is presided over by a strange, yellow, ball-organism, Onsokumaru. While he knows nothing about being a ninja master, he loses no opportunity to exploit the dim but cute Shinobu. On a mission to steal all the panties from area high school girls, Shinobu meets Kaede who gets drawn into the surreal, ecchi, but fun world of Shinobu. (Source: ANN)
