The Hidden King

Rokujo Minharu (voiced by Rie Kugimiya), who has an indifferent personality and doesn't care about the things around him, seems to be just an ordinary high school student, but his body contains the most powerful secret technique in the ninja world, "Senra Vientiane". This ability was coveted by many people in the ninja world, and even attracted the Iga ninja tribe to mobilize collectively, vowing to bring Renqing back to dig out the secret skills in her body. At the same time, Renqing's English teacher Yunping (voiced by Daisuke Namikawa) and his classmate Aizawa Hongichi (voiced by Hino Satoshi) are ninjas in the world, and their assigned tasks are to protect Renqing's safety. A battle for "all kinds of things" begins, and all kinds of characters will also appear. And if Renqing wants to live a normal life, there is only one way, which is to become the legendary Hidden King... This film is adapted from the comic of the same name serialized by Yuki Kamaya in "Monthly Gfantasy". The series has now been completed.
