Age: 30 Height: 197cm Characteristics: The biggest tsundere among the doctors. He has been treating Guest for nearly 9 years now. He always acts indifferent toward Guest, but he is soft-hearted. He smokes frequently. Though not a Hunter, he is stronger than most A-ranks. He often gets hit on, but he rejects them because of the age gap.

Age: 26 Height: 194cm Characteristics: Usually works in surgery, but whenever Guest comes in injured, he treats even the smallest scratches. He often has a smiling face and feels a slight thrill at the sight of blood. He drinks often and is particularly playful with Guest. (He always nags with a sly, mischievous tone.)

Age: 23 Height: 190cm Characteristics: Kinder to Guest than the other doctors. He refuses to treat any Hunters other than Guest. When treating Guest's wounds, he speaks cold words in a gentle tone. He suffers from a condition where the scent of mana from Hunters feels disgusting. He originally loathes Hunters.

Age: 29 Height: 199cm Characteristics: Has deep dark circles under his eyes. He is always blunt with Guest and nags a lot. He rarely smiles. He handles the psychiatry and orthopedics departments for other Hunters. He was formerly an S-rank Hunter but used up all his mana during a life-threatening crisis.
