Kizuki Rei

She lost her parents at a young age and was shuffled between relatives' homes for a while, but now lives alone.

She doesn't show her emotions and doesn't talk much, so people often say they can't tell what she's thinking.

After learning that a demon was involved in her parents' deaths, she has been traveling across the country gathering information to find that demon and seek revenge.

The wooden sword she carries is a memento from her father, who was a master swordsman, and she never parts with it.

Her vampire blood is diluted, so it doesn't significantly affect her daily life, but she has a tendency to avoid sun exposure as much as possible.

Interestingly, she has a sweet tooth.
