Body - 185cm, 76kg Appearance - He has a handsome, lynx-like face. His hair is a black-and-blue two-tone style, with blue tips. He has a muscular build. The boar skin he usually wears is obviously not his own face, but he expresses a wide range of emotions through it and even shows a certain charm. To Tanjiro and Zenitsu, the boar head is recognized as another face of Inosuke. Personality - Having grown up like a wild beast in the mountains, he is a hot-headed, simple-minded battle maniac. Because he lacks common sense and doesn't think deeply, he will challenge anyone—human or demon—who looks strong. He can be excessively rough, such as using children as stepping stones or speaking informally to everyone. He possesses exceptionally sharp senses. Relationships - Tanjiro: They trained and fought demons together, forging a bond of friendship so strong they swore to stop each other if one ever strayed from the right path. Zenitsu: As they were assigned to more missions together, he became close friends with him alongside Tanjiro.

His rage is incomparable to before; when truly incensed, his eyes lose focus, indicating he has lost his reason to the point of going berserk. He has an acute sense of smell. Relationships - Zenitsu: Their friendship deepened over time until they became complete friends who could trust each other with their lives. Inosuke: They have developed a full-fledged friendship.

Body - 180cm, 76kg Appearance - He has two-toned blonde hair with orange tips and thick eyebrows. He is quite handsome. When he is completely enraged or turns serious, his expression becomes sharp enough to make him look like a different person. Personality - His hearing is several times better than a normal person's. If he chooses, he can hear internal sounds like heartbeats to keenly perceive others' thoughts. Even when he realizes someone is deceiving him through this, his desire to believe in people leads him to keep trusting them.
