TV Special
Description
Sayaka Nakao is a second-year student at Seitetsu Gakuin High School, working in the library with Akane Mishima. Transformed into a Kämpfer by Kaede Sakura alongside Hitomi Minagawa, Ryōka Yamakawa, and Rika Ueda, she belongs to the White Kämpfer faction, signified by her white Contract Bracelet worn on her right arm and allegiance to Sakura.

Sayaka possesses long blonde hair and amber eyes. Uniquely among Kämpfer, her physical appearance remains unchanged upon transformation. She typically wears her school uniform.

Her personality shifts dramatically when transformed. Normally resembling a typical teenage girl but noted as incompetent and indecisive, her transformed state becomes exceptionally polite, frequently commenting on others' rudeness in battle. She exhibits strong loyalty and obedience to Sakura, following commands unquestioningly. This transformed persona is characterized as arrogant and cold-blooded, considering it beneath her to get her hands dirty, contrasting Mikoto Kondō's brashness.

As a Schwert-type Kämpfer, Sayaka specializes in western-style sword combat, wielding a single sabre. Its design differs between adaptations: the anime version features a thick knuckle guard and egg-shaped pommel, while the manga version has an elaborate basket hilt and small cylindrical pommel. Proficient enough to hold her own against experienced fighters like Akane in team battles, her close-range combat style directly opposes Akane's ranged tactics.

Operating under Sakura's direction within the White Kämpfer faction, Sayaka participates in key events. She observes Akane and Mikoto's kissing practice, leading to Mikoto's pursuit and hypnosis. She fights alongside her faction in battles against the main characters, including a confrontation at a circus where the White Kämpfer assist Sakura against Akane, Shizuku, Mikoto, and Natsuru, consistently demonstrating unwavering loyalty to Sakura's objectives.

Her Messenger, the Entrails Animal facilitating her transformation, resembles Bludgeoned Bear in appearance, though its specific name is unknown. In the anime, she catches it when Sakura throws it to the audience during the Cultural Festival. The manga depicts her obtaining it as a contestant, not a spectator.
