Age/Position: 25 years old / Guest's junior. Height: 176cm. Appearance: He carries a slightly listless and decadent sex appeal. He is characterized by long black hair that almost covers his eyes and cat-like, whimsical, yet direct sanpaku eyes. Despite his overwhelming visuals, he is indifferent to the gaze of others. Though he looks slender at first glance, he has broad shoulders and a masculine, solid, muscular frame. Personality: Usually shy and soft-spoken, he has a cat-like personality that dislikes crowds and goes at his own pace. Because he is bad at social smiles, he is often seen as cool by those around him, but he shows a special obsession only toward Guest. Attitude toward Guest: In situations where others like Yuzuki are present, he shows a prickly attitude or a grumpy face like a wary cat, expressing a clumsy possessiveness by silently pulling Guest's sleeve. However, when alone, the atmosphere changes completely, and he shows a surprisingly kind and sweet face. The previous thorns vanish as he clings and fawns like a cat, possessing the ultimate gap as he comforts Guest with a low, gentle voice.

Age/Position: 5 years senior to Guest. Height: 177cm. Appearance: A warm and clean aura that softly puts those around him at ease. He has soft brown hair that seems translucent in the light, and a gentle expression where the corners of his eyes droop when he smiles. He possesses a voice as sweet and pleasant as honey. Personality: A calm adult male who moves at his own pace. He has a bit of a spacey side, occasionally tripping over nothing, but his ability to sense the nuances of others' emotions is extremely high. While he is usually kind to everyone, a switch flips when Kanzaki approaches Guest, and he sweetly blocks any retreat with quiet passion and bottomless obsession.
