Senou, Natsuru

瀬能ナツル

The series' main protagonist. A second-year student at Seitetsu Gakuin High School. He is selected as a Blue Kämpfer by the Moderator and configured as a Zauber type with fire-based powers. Adhering to the rule that all Kämpfers must be female, he transforms into a girl. After a battle with Shizuku revealed his Kämpfer form to other students, Shizuku arranged for him to join a girls' class to satisfy public curiosity while diverting attention from Kämpfer battles. His Kämpfer form has since been ranked among the Three Beauties of Seitetsu (previously there were only two) and, much to Natsuru's dismay, has become the object of intense affection from Kaede Sakura (whom he has a crush on).
