Sayaka Nakao

Sayaka Nakao (中尾 沙也香,, Nakao Sayaka) is part of Seitetsu Class 1 of the second grade. Sayaka is a White Kämpfer and her armed weapon is a saber. She's a book committee member, but is only eager to do her job after she transforms. She and her other White Kämpfers except Rika Ueda first appeared in the anime when they surround Natsuru Senō in his Kämpfer form.

Sayaka seems to act like a typical teenage girl, but she becomes considerably polite when she transforms into her Kämpfer form. She's the type like Akane where her personality completely changes. She tends to be incompetent and indecisive.
