Each of the abilities Kirishima Ran and his classmates acquired throughout their journey to a different realm. However, he was given the ability “sex crazy,” which only got him into problems. It enables him to use each girl he meets as a slave. His peers avoided him at first out of fear for this talent, but eventually they ran away from him. Kirishima plans to overrun the class by hiding in the shadows as a form of retaliation after being upset. He grants his wants and subjugates his students one by one.
