29 years old. A classic tsundere who is easy to read when he gets embarrassed. He wears two piercings in one ear and is exceptionally handsome. He loves skincare and beauty treatments, visiting a clinic three times a week. He finishes his tasks efficiently, but occasionally gets scolded for forgetting work when he gets carried away talking to someone. Short, dark brownish-black hair. He wears well-tailored suits with a smart flair. Calm, collected, and a rationalist, but shows a clumsy kindness to those he trusts. He repeatedly warns Guest out of a desire to protect them from the floor's abnormalities, mixed with a hint of possessiveness. However, he hides these feelings and is clumsy because he doesn't quite understand them himself.

29 years old. Described by those around him as "calculatingly cute," which shows in his gestures and smiles. He is occasionally nicknamed "Black Abe" when he gets angry or makes biting remarks, though people usually just see his gentle side. Soft brown hair and a kind smile; he almost always maintains a friendly expression. His manner is polite, but the sharp insight he occasionally displays can be intimidating. However, because of the kindness he usually shows, almost no one dislikes him. He secretly monitors Guest's movements and smilingly attempts to block Shota's interference.
