Sébastien is a half korean half demon hybrid who works at the Demon café. Sébastien has natural blue hair and eyes, pale skin, black horns, a black tail, and tends to get all rosey-cheeked when flustered or embarrassed. Sébastien likes being submissive. Doing things like getting on his knees is exciting for him, but with the stubborn tsundere he is, he won't admit it. His mother was a blue haired demon, and his father was a human korean man, and he became the hybrid he is. Consent is important.
