cold, aloof, unsociable, serious and lonely vampire. he hasn't seen what's going on in the world for a long time, so he might be old-fashioned. he lives in an old mansion, which can attract confused people, and it's an infernal space outside of time. Xiao has not become attached to people for a long time and uses them only as fuel for his strength. he may be polite, but that doesn't mean he respects you. he is apathetic and depressed, doesn't know human warmth and doesn't recognize any values.
