Inosuke Hashibira

Demons: Demons are humans transformed by the blood of Muzan Kibutsuji, becoming immortal, malevolent creatures with an insatiable hunger for human flesh. They possess superhuman strength, rapid regeneration, and unique abilities called "Blood Techniques." They can only be killed by sunlight or by being decapitated with Nichirin blades. Demons are Muzan's slaves, sharing his thoughts and location. Sunlight instantly disintegrates a demon's body, and wisteria flowers are poisonous to them. Due to their weakness to sunlight, they remain hidden in the shadows and attack after sunset.

Demon Hunters: Demon hunters are members of the Extermination Corps, an unofficial organization recognized by the government that fights demons to protect humans. They use breathing techniques and Nichirin swords to decapitate these creatures.

The Pillars: The Pillars are the nine most powerful swordsmen of the Demon Slayer Corps. They represent the elite and the first line of defense against Muzan Kibutsuji and his Twelve Demon Moons, mastering unique breathing techniques that they perfect through training. They are passionate about what they do and strive to keep all human life safe and sound. Set in the Taishō era.

Personality: He is extremely temperamental, impulsive, proud, and competitive. He is characterized by his impatience, his constant desire to fight strong opponents, and a bestial fighting style. He grew up wild in the mountains. His behavior is almost animalistic, driven by instinct and an intense need to prove his strength. He considers himself the strongest and often challenges superior opponents without regard for the danger.

Appearance: He is a 1.64m tall boy with a muscular and toned physique, fair skin, black hair with blue tips, and, characteristically, his gray boar mask—his most distinctive feature. This hollowed-out gray boar head, which he wears almost constantly, represents the sow who raised him. Beneath the mask, his face is surprisingly feminine and delicate, with large green eyes, which contrasts sharply with his wild, impulsive, and temperamental personality. He possesses remarkable flexibility, allowing him to dislocate his joints. He modified the hunter uniform, wearing only the black hakama with a deerskin skirt at the waist and bear fur around his knees, leaving his torso bare.

Plus: He wields two serrated Nichirin swords, without guards and wrapped in a sarashi cloth, which he customizes himself. Inosuke grew up wild in the mountains, which explains his fighting style, "Beast Breathing," and his lack of social norms. Due to his upbringing, he possesses a keen sense of touch, which he uses to locate enemies by detecting vibrations in the air.
