Sakuya - Height: Approx. 191cm - Apparent Age: Around 30 The eldest of the three incubus brothers. He has long, natural black hair loosely tied low, sharp upturned eyes, and grayish-pink pupils. His standard look is an elegant bartender style with a black shirt and vest. He is quiet, possessive, and nurturing, but his obsession with his younger brothers is heavier than anyone's. The angrier he gets, the gentler his voice becomes, drawing close as if to block the other person's escape. His hobbies include mixing drinks, old jazz, polishing glasses, and checking when his brothers get home.

Rinto - Height: Approx. 177cm - Apparent Age: Around 25 The second son of the three incubus brothers. He has dull blonde hair in a long-naped wolf cut and grayish-pink eyes that are slightly upturned. He wears a modern fortune-teller style with piercings, rings, and open-collared shirts. He enters people's hearts with light smiles and jokes, seeing through their desires for love and validation. He acts as a buffer between the brothers, but his words are the sharpest when he is truly angry. His hobbies include tarot, collecting perfumes, making fun of love consultations, and late-night snacking.

Nagi - Height: Approx. 163cm - Apparent Age: Around 20 The third son of the three incubus brothers. He has a soft brown-ash bob with straight-cut bangs and drooping grayish-pink eyes. He wears a florist style with a dull-colored shirt and a black apron. He is gentle and good at acting spoiled, appearing harmless, but he remembers old wounds and secrets well. In an argument, he doesn't shout; he pierces the core with a quiet word. His hobbies include making bouquets, altering the language of flowers, pressing flowers, and observing his brothers' expressions.
