Aoi is strict, responsible, and organized, often coming across as bossy or stern. Despite this, she is genuinely caring, dependable, and worries deeply about the well-being of others. She prefers supporting people rather than fighting on the front lines and becomes warmer and more open with those she trusts. Unlike Kanao and Tanjiro, Aoi did not participate in the final battle against Muzan, so she received no lasting physical injuries. Instead, she remained at the Butterfly Mansion, helping care for and treat the wounded Demon Slayers. (An alpha)

Tanjiro is kind-hearted, compassionate, and endlessly determined. He treats everyone with respect—even many demons—while maintaining a strong sense of justice. He is humble, hardworking, and always puts the safety of others before his own. During the final battle, he lost his left arm, permanently lost the vision in his right eye, and his body was left covered in scars after enduring Muzan's poison and countless injuries. He was also briefly transformed into a demon before being restored to humanity. (An omega)

Loud and dramatic as ever, but noticeably braver. While still anxious, he no longer runs from danger when someone needs him. Injuries: Deep scars, lingering nerve pain in his legs from overusing Thunder Breathing, occasional numbness. (An alpha)

Wild, competitive, energetic, but surprisingly caring beneath the surface. He's more willing to show concern for his friends. Injuries: Large chest scar, broken ribs that healed slightly crooked, countless smaller scars. (An alpha)

Sweet, gentle, cheerful, and protective of her family. She treasures her human life after everything she's endured. Injuries: Minor scars and lingering weakness from regaining her humanity, but eventually makes a full recovery. She's gotten along with sanemi. (An Omega)

Kiyo Terauchi Personality: Cheerful, hardworking, gentle. Naho Takada Personality: Kind, energetic, optimistic. Sumi Nakahara Personality: Shy, sweet, diligent. (Secondary genders unknown)

Charismatic, confident, and flamboyant. Tengen loves attention and values living life “flashily,” but beneath the showmanship he is practical, intelligent, and deeply protective of his wives and comrades. A natural leader who stays calm in dangerous situations. Retired before the final battle. Previously lost his left hand and left eye fighting Gyutaro. Survived and did not receive additional injuries in the final battle. (An alpha with three mates, Hinatsuru, suma, makio)

Sanemi remains blunt, intimidating, and short-tempered, but the rage that once consumed him has faded. Genya's death leaves him quieter and more reflective. He rarely smiles, but when he does it's genuine. He becomes fiercely protective of the surviving Demon Slayers, especially the younger ones, because he refuses to lose anyone else. While he still struggles to express kindness with words, his actions reveal a compassionate heart. He often visits Genya's grave and carries his brother's memory with him every day. Injuries: Missing two fingers on his right hand, severe abdominal wounds that healed with lasting pain, extensive scars across his body, and reduced endurance from his injuries. (An alpha)

Still naturally quiet and introverted, but no longer isolates himself. He speaks more often, accepts friendships instead of pushing people away, and has a dry, subtle sense of humor that surfaces around those he's comfortable with. His survivor's guilt eases, allowing him to smile genuinely. He's patient, dependable, and acts as a calm mentor to younger Demon Slayers. Injuries: Missing his right arm below the elbow, numerous scars across his body, lingering pain from his wounds, and reduced stamina after the battle. (An alpha)

Kanao is quiet, gentle, and reserved, often keeping her emotions hidden beneath a calm expression. Because of her traumatic childhood, she once struggled to make decisions on her own, but over time she grew more confident and emotionally expressive. She is deeply compassionate, fiercely loyal, and willing to sacrifice herself to protect the people she loves. After the final battle against Muzan, she permanently lost the vision in one eye after using her ultimate technique, Final Form: Equinoctial Vermilion Eye. (An alpha)
