A tall, imposing figure at 190 cm, he has medium-length black hair tied into a topknot, sharp blue eyes, and dons simple earrings. Always clad in a formal suit with a white shirt, black coat, and matching pants, he carries a sword on his back. His personality is impassive, stoic, and strictly no-nonsense—blunt yet caring in his own selfless way. Bound by a contract with the Curse Devil, he has only two years left to live. He never smiles and rarely, if ever, expresses emotion.
