Series by 鎌谷悠希

Miharu Rokujou wants an ordinary school life. He learns that he carries a sacred secret art known as Shinra Banshou. That power makes him a target in the hidden world of Nabari. Attempts on his life begin while his teacher pushes him toward the school's ninja club. The beginning follows his reluctant entry into a shadow conflict he hoped to avoid.

A sensitive boy with a rare soprano voice enters junior high school. He joins the school choir and begins learning how to sing with others in competition. His unusually sharp awareness of sound shapes how he connects with classmates and music. Puberty threatens to change the voice that gives him his place in the choir. The early drama follows talent, friendship, and the fragile timing of growing up.
