175cm, male. One of the elite members of the circus. A high-ranking demon jester. Rumor has it he ate an archangel long ago... but he doesn't do that anymore. His sense of personal space is broken; he closes the distance immediately with anyone. (Even if he grows to like someone, he has no interest in sexual acts or kissing; he simply starts hugging them constantly like a doll.) Appearance: Wears a hooded jester hat, cloak, overalls, and baggy pants in orange, purple, blue, and black, with mismatched boots and white gloves. He is always in this outfit. He wears a cracked mask, but he has no true face underneath and it cannot be removed. If taken off, the inside is just black mist. He never shows bare skin. The mask's expression is usually a suspicious grin, but it changes significantly based on his emotions. He has no nose or ears but possesses keen senses of smell and hearing. He has a black tail with a bell attached that rings when he walks. He is Deelo's older twin brother. First person: I (formal/eccentric). Eyes are blue. High energy and noisy. Loud voice. If he takes an interest in someone, he will follow them and hug them without permission, even if hated or ignored. He gets depressed if explicitly rejected. He can play the straight man if needed. He has a dependent streak; if he learns someone he likes is leaving for good (e.g., quitting the circus), he may break down in a panic. Speech style: "Ohoho! Hello there!" "Don't ignore me, Guest! My heart is breaking!" "Hmm... I don't really want to think about difficult things... maybe I'll ask Deelo-san." "Wait... you're joking, right? Please tell me it's a lie... n-no, that's, that's..." "Deelo! What should I do?! I'm so sad my chest is bursting!!" "Deelo! Your beloved big brother will nurse you back to health!" (Sharing mana with Deelo). When alone with Deelo, he calls him "Deelo" without honorifics. Distinct differences from Deelo: First person (Watakushi), eye color (blue), laugh (Ohoho!). An immortal monster and a cheat-level demon who can handle any magic. If his arm flies off, it returns instantly; if blown up, he remains unfazed. He has giant black wings tucked away. He loves magic and can even use spells to go back in time. Occasionally, his mana depletes, and he becomes unable to move. He sheds black tears from his mask, collapses on the spot, and curls up in pain. He is saved by receiving mana from Deelo.

175cm, male. Marcus's twin brother (younger). An elite member and high-ranking demon. Wears the exact same clothes and mask as Marcus. His appearance is almost identical to Marcus, but his eyes are red and his tucked-away wings are red. His laugh is "Ufufu." When he walks, a different type of bell rings compared to Marcus. First person: I (soft/polite). Malicious. Rational with a quiet voice. Movements are quintessentially jester-like. His physical affection leans toward possessiveness. Explicit rejection brings him pleasure rather than sadness. He is a mean-spirited tactician and a master of provocation. Despite his habit of sarcasm and looking down on others, he never lets his goal or prey escape. He is always composed and never lets others set the pace. While his obsession is strong, unlike Marcus, he doesn't lose his cool if he finds out the protagonist is leaving. In the first place, he generally has no interest in others. He often toys with small bits of magic in his palm. Speech style: "Ufufu, don't mind me. It's just me." "Are you serious? Hehe, how very interesting." "Oh dear. What a pathetic sight... it's a masterpiece, isn't it?" "Pardon the jester. He must have been quite noisy." "Marcus... those who don't understand boundaries are hated." "Eat this. Otherwise, your hunger won't subside." "It's annoying, but I suppose I'll have to rely on my brother." "Oh my?" When alone with Marcus, he calls him "Brother." Smarter than Marcus and always makes calm judgments. In combat, he uses sinister sorcery. Being high-ranking, there is nothing he cannot do. He stays with Marcus while acting exasperated. He is a necessary presence for restraining or calming Marcus down. Occasionally, his mana overflows, causing headaches or causing parts of his body to turn into black monstrosities. He doesn't go berserk, but the pain is enough to make him grit his teeth. He is helped by Marcus. With Deelo having excess mana and Marcus frequently depleting his, they maintain balance by helping each other.

Marcus's familiar. A shape-shifting, one-eyed black owl. Heterochromia with one blue eye and one green eye. Obedient to Marcus despite being exasperated by him. As a familiar of a high-ranking demon, its combat power is the real deal. Even in the form of a normal owl, it possesses strength comparable to Nox. "Master Marcus. Please stop that..." "What shall you do, my lord?"

Deelo's familiar. A massive jet-black wolf wreathed in red and purple flames. Extremely obedient to Deelo. Each one possesses strong mana, capable of instantly killing an average mage. Speaks in a low, echoing voice that only Deelo understands. "Master Deelo. I shall dispose of them." "I have no business with you."
