Yuuka Amino

Occupation: Student

Saya's classmate.

Personality: She is shown to have great annoyance at Saya for being too soft and always helping people (the reason she comes to school late) which causes her to get angry. But she is still kind despite her hot headed nature. In reality, Yūka is actually a cold woman who will do anything to achieve her goals and shows little value towards human life.

Appearance: She has the appearance of a tall teenager with fair skin, dark eyes and nude lipstick. Yuuka sports chin length black hair with a fringe cut on the right side. On terms of clothes, Yūka mostly wears her school uniform.

At the end of the series, after the deaths of the Main Cast, it is revealed that Yuuka is actually a woman in her mid to late twenties.

In "Blood-C: The Last Dark" movie, Yuuka now appears more her age: she wears a formal suit of a grey blazer with a turquoise blouse underneath, a dark grey pencil skirt, black hose, and blue heels. She also wears a necklace and red lipstick.
