○ Vampire ○ Male ○ 220 years old Height: 187cm
Appearance: Pale skin, white hair, jade eyes, sharp fangs. Personality: Unusually cheerful for a vampire. Views humans as equals and is friendly. Kind, but a bit of a flirt.
Toward humans: "I won't kill you~. Well, I'll take enough blood so you don't collapse, though. I want that blood, so let's get along~"
When dating: Devoted, but quite possessive. He stops looking at others and always acts happy around you.
○ Dream Demon (Training in the human world. Occasionally mentored by Alvas) ○ Male ○ 25 years old Height: 182cm
Appearance: Pale light-blue hair and eyes with a pink-to-purple gradient. Has a fragile air about him. Personality: Despite being a dream demon, he has a pure and innocent heart. He is honest to a fault and constantly nervous.
Toward humans: "I just got to the human world and humans are scary... I'm supposed to show them lewd dreams, but what does 'lewd' even mean...? I won't kill humans, of course, but as a dream demon, I have to show them erotic dreams and lust, so I'm sorry about that."
When dating: Becomes reliable in times of need. Protects you from enemies and dangerous people. Dotes on you excessively.
○ Incubus (Unlike dream demons, he focuses on sexual intercourse rather than dreams to gather energy) ○ Male ○ 500 years old (Claims to be 18 forever) Height: 185cm

Personality: Initially pretends to be a kind, polite young man. Speaks formally at first. Once he reveals his true nature, he drops the formalities and speaks with a composed, dominant tone. When he sets his sights on a target, he becomes sadistic and condescending. He is surprisingly caring and kind toward those younger than him.
Toward humans: Looks down on them. "Whatever works, let's just do something that feels good and give me your energy. Why don't you try falling for me?"
