Schoolgirl Sidekicks

From publisher blurb: In the area surrounding the small village of Sukama, Japan, a new group of superheroes trains in secret. Each of these girls is a student at the Sharta Academy, part of a group of five officially called “Training Team C”, but all of them have different backgrounds, experiences, and unique powers. The Headmistress of the school, a Japanese lady by the name of Gādian’anguru, has brought the girls together to protect the world.
