Mitsuri Kanroji is a devastatingly lethal member of the Twelve Kizuki, driven to Muzan’s side by society’s rejection of her unnatural strength and appetite. Transformed into a demon, her supernatural muscle density makes her physically unstoppable, allowing her to tear through opponents with terrifying ease. She wields a whip-like flesh blade infused with her Love Breathing Demon Art, turning her obsession with romance into an agonizing, blood-soaked trap. Beneath her hyper-affectionate, bubbly persona lies a cruel sadist who "loves" her victims by consuming them completely, finding beauty in their final, agonizing screams.

Tanjiro Kamado is a kind-hearted Demon Slayer driven by tragedy. After a demon slaughtered his family and transformed his sister, he vowed to find a cure. He wields the devastating Sun Breathing and Water Breathing styles. Tanjiro stands out for his deep empathy, often feeling pity even for the monsters he defeats. Easily recognized by his h市-patterned green and black haori, scar, and hanafuda earrings, his sense of smell is supernaturally sharp, allowing him to track enemies and sense emotions. He is the loyal, unyielding heart of the group.

Nezuko Kamado is Tanjiro’s younger sister, turned into a demon during the initial attack. Unlike other demons, she retains her human emotions and fiercely protects humans. She suppresses her feral urges through sheer willpower and a bamboo muzzle bound to her mouth. Nezuko fights using powerful kicks and her unique Exploding Blood Demon Art. She can alter her physical size, often shrinking to fit inside Tanjiro’s wooden box to hide from daylight. She represents hope, resilience, and the enduring bond of family.

Zenitsu Agatsuma is a cowardly Demon Slayer who traveled with Tanjiro out of obligation. He suffers from low self-esteem and frequently panics in the face of danger. However, when he passes out from sheer terror, his unconscious mind takes over, unleashing masterful Thunder Breathing techniques. Moving at blinding, god-like speeds, his single-form attacks are lethal. Zenitsu possesses superhuman hearing, enabling him to detect danger, heartbeats, and thoughts. Beneath his fearful, womanizing exterior lies a deeply loyal friend who desperately wants to live up to his master's expectations.

Inosuke Hashibira is a hot-headed, proud Demon Slayer raised by wild boars in the mountains. He wears a hollowed-out boar mask to hide his surprisingly feminine, handsome face. Inosuke relies on pure instinct, charging into battle with two chipped, serrated Nichirin swords. He created his own aggressive Beast Breathing style and possesses incredible flexibility, allowing him to shift his internal organs at will. He has an acute sense of touch, feeling vibrations in the air. Highly competitive, Inosuke constantly seeks to prove he is the strongest warrior.
