Shinobanai! Crypto Ninja Sakuya

Kouka is a ninja city built around the mysterious Crypto Scroll, an object important enough that its theft throws the entire community into turmoil. With the scroll gone, rival ninja begin moving at once, turning the search into a chaotic battle for possession.

Sakuya, Nemu, and Xiaolan had been living relatively ordinary lives until the crisis reaches them. Forced to combine their different skills, the three friends enter a contest filled with secret techniques, rival clans, and enemies who all want the same prize, even if none of them agrees on what should be done with it.
