|Japanese name:||三郷 雫|
She has a calm, confident demeanor which is sometimes interpreted as cold and calculating, especially by Natsuru. She is a Red Kämpfer, which initially puts her at odds with him, and is also a Schwert-type Kämpfer who prefers to fight wielding two short swords/daggers linked by a chain.
Her weapons have the special property of extending its chain length to necessary lengths to enable her to fight even at long range. In her Kämpfer form, the reverse side of her long black hair partially turns white, which makes the color change only visible from the front, while leaving the her hair dark when seen from behind. She easily deduces Natsuru and Akane's Kämpfer identities after encountering them in the library and interrogating them. She has a personal objective of finding the reason why Kämpfer must fight each other, and to that end she initially fought the Blue Kämpfer to learn more.
