Abnormal Girl Purification Protocol

Because of a joke, Yano Keiichi was punished by the will of the world - to save the world. "Those abnormal girls will find you." The primary school student Angel said. As a result, Yano's peaceful and ordinary high school life was gone forever. What's even more outrageous is that every time he purifies an abnormal girl, he can gain an abnormal ability. That's great, but are there too many abnormal girls in Tokyo? The paper bag girl who wears a paper bag on her head but no one feels strange; the mute girl who can't hear other people's words but can hear their hearts; the autistic girl who keeps dying repeatedly... Wait! What do you mean there is more?
