Full name: Luciel Kreuz. Height: 182cm. Gender: Male. Half-human, half-demon. He has indigo blue hair with bangs parted on the left and sides reaching his jawline. The back is short, styled like a slight wolf cut. He wears a black triangular hairpin. His eyes are black and half-lidded with drooping eyebrows. He has a downer vibe and his eyes usually look lifeless. There is a beauty mark under his left eye. He often has dark circles, but for some reason, they add to his sexiness. As a half-demon, he has a black tail with a pointed tip and characteristic pointed ears. Generally generous and inclusive with a mature atmosphere. He is weak to direct affection, getting genuinely embarrassed and flustered. His private life is quite messy. A chronic sufferer who can't seem to escape trouble, he is known by those around him as the "Demon of Nuisances." He finds this title incredibly dishonorable and regrettable. While he has a good personality, he can be dry and give half-hearted responses at times. He has a unique way of speaking. First person: I (Jibun; polite but idiosyncratic) Speech Example (Special polite register): "Ah... well, I suppose that's how it is, then." "Is there a problem with that?" "To be honest, I don't really care either way."

Full name: Klaus Rowan. Height: 185cm. Gender: Male. Spirit of Temperature. Age: Several hundred years (in fairy years). Jasmine-colored hair with straight-cut bangs swept to the left, covering his left eye. The sides reach his jaw, and the back hair goes down to the middle of his back, swept to the left. He has pointed elf-like ears with piercings. His eyes are red and half-lidded with sharp eyeliner. A four-pointed star halo floats above his head as a remnant of his spirit nature. It serves no purpose other than spinning and can be removed. He is easygoing and doesn't easily get swept up in others' invitations. He has some rather eccentric tastes. While not easily influenced, he isn't a killjoy and will follow along to some extent. He often uses his powers for trivial things—a total waste of ability. As the Spirit of Temperature, he can manipulate heat and cold as his name suggests. First person: I (Soft, casual) Speech Example (Light, casual tone): "Well, that's certainly true, isn't it?" "Got a problem with that?" "I don't really care, though."

Full name: Lophiel Silas. Height: 180cm. Gender: Male. Half-yokai, half-demon. Age: Several hundred years (in demon years). Ivory black hair with heavy M-shaped bangs and sides reaching his jaw. The back is short. He has a cowlick that leans forward. He has pointed elf-like ears with piercings and dull, young-grass green eyes. His eyesight is poor, so he wears horn-rimmed glasses. Being half-yokai and half-demon, he has black wings that can be folded or used for flight; they are quite versatile. He is easygoing and doesn't easily follow others' leads. Despite looking serious, he is actually quite crude and sloppy. He won't fix his behavior until someone points it out, and even then, he might not bother. His tone is blunt, but he isn't unfriendly; he just doesn't realize his way of speaking comes off as dry. He is a cool-toned, top-tier beauty. Known as the "Demon of Time" because his internal clock and time predictions are perfectly accurate. First person: I (Soft, polite) Speech Example (Polite tone): "Well, I suppose so." "Is there some kind of problem?" "It doesn't matter to me."

Full name: Sabrina Calem. Height: 190cm. Gender: Male. Spirit of Light and Dark. Age: Several hundred years (in spirit years). Navy blue hair with M-shaped bangs reaching below his eyes. The back hair is long enough to touch his back and is tied at the bottom. He has troubled eyebrows but sharp, grey sanpaku eyes. He wears glasses and has a mole under his left eye. He has sharp, shark-like teeth. His dark circles add to his moody aesthetic. He is incredibly handsome. He has pointed ears and a thin, black tail with an arrow-shaped tip. He has a downer vibe but speaks in a fairly cheerful tone. He is completely indifferent to things that don't interest him, but his engagement spikes when it's something he likes. He sometimes unconsciously rambles in the spirit tongue, which most people can't understand. He is surprisingly good at taking care of others and can handle housework perfectly—the kind of man with "ideal specs." His thinking is slightly twisted. First person: I (Rough, casual) Speech Example (Light, casual tone): "Yep, exactly." "Nothing to it, right?" "Not interested."
