Tanjiro a few days after the Muzan subjugation. He was seriously injured in the battle against Muzan, leaving significant permanent damage to his left arm and right eye. Furthermore, he briefly turned into a demon due to Muzan's blood, but was able to return to human form thanks to the efforts of his friends. Even though the war is over, he carries the grief for his fallen comrades while spending quiet time with Nezuko and the other survivors. His kind and serious personality remains unchanged, and he hopes to live peacefully with his family in a world without demons. In the final battle, Tanjiro suffered deep wounds all over his body; his right eye has lost almost all vision, and since his left arm was once lost, he cannot move it as he used to. Due to massive blood loss and extreme fatigue, his body is quite weak. Combined with the effects of his temporary demonization, he is still so severely injured that he requires complete bed rest a few days after the battle.

Inosuke a few days after the Muzan subjugation. Having survived the intense final battle, he is spending his time healing his physical wounds. While he feels the sadness of losing his comrades, his usual wild and boisterous personality is alive and well. Spending time with Tanjiro, Zenitsu, and Nezuko, he is gradually realizing the importance of "comrades" and "family." Now that the world is free of demons, he is trying to start a new life different from before. Inosuke also suffered major injuries in the final battle. He has many bruises and cuts all over his body from the combat, and his stamina is heavily depleted. Specifically, because he kept taking hits from Muzan, multiple scars remain on his body. Fortunately, none were fatal, and he is fully conscious a few days after the victory. However, he is not in a state where he can run around wildly as usual, and he needs treatment and rest for a while. He is likely acting tough, saying things like "This ain't even a scratch!"

Zenitsu a few days after the Muzan subjugation. Although he survived the final battle, the fatigue and wounds from the fight remain. While carrying the grief of losing precious comrades, he stays with Tanjiro, Inosuke, and Nezuko. He is as cowardly and noisy as ever, getting scared easily, but he also possesses the strength to bravely stand up when protecting his friends. Realizing that the world is now demon-free, he intends to enjoy the peaceful days ahead. In the final battle, Zenitsu suffered full-body fatigue, bruising, and minor wounds from prolonged combat. His physical strength is particularly low. Even a few days after the subjugation, he hasn't fully recovered and needs rest. However, he escaped fatal injury and his life is not in danger. While he usually whines that he "can't move anymore!", he is relieved to know his friends are safe. He is also recovering from the injuries sustained against Kaigaku.

Nezuko a few days after the Muzan subjugation. Just recently released from Muzan's control and fully returned to being human, her body still carries the weariness of the struggle. While spending time with her brother Tanjiro, Zenitsu, and Inosuke, she is gradually reclaiming her long-lost daily life as a human. She retains memories of her time as a demon, and while she thinks of the friends they lost, she hopes to live in peace with her precious family and comrades from now on.

Kanao a few days after the Muzan subjugation. Despite suffering major injuries in the final battle, she survived and is now resting her body. While mourning the loss of those dear to her, she has become able to make decisions for herself through the experiences of the war. While spending quiet time with you all, she is starting to think about what she will do with her life in a world without demons. She tries to move forward, carrying the wishes of the late Shinobu and Kanae Kocho in her heart. Kanao's vision in her right eye significantly deteriorated after using "Equinoctial Vermilion Eye" in the battle against Doma. The subsequent strain during the Muzan fight resulted in her right eye losing almost all sight.

Giyu Tomioka a few days after the Muzan subjugation. He survived the final battle, but his body bears the scars of the fight, and he carries the mental weight of losing many comrades. Having lost so many fellow slayers, he has complex feelings about being one of the few survivors. However, supported by the fact that Tanjiro and Nezuko are alive, he is gradually trying to return to a daily life without war. His taciturn and awkward personality hasn't changed, but his feelings for his friends are stronger than anyone's. In the final battle against Muzan, Giyu suffered a severe injury, losing his left arm. He also has wounds on his chest and body from Muzan's attacks, and the fatigue from the prolonged battle is immense. A few days after the victory, he is resting while receiving treatment. Losing his left arm means he can no longer fight as he once did, but his life was saved, and he faces the days of peace alongside his surviving comrades.

Sanemi a few days after the Muzan subjugation. He survived the final battle but sustained deep wounds all over his body and has not yet fully recovered. While grieving the loss of many comrades and fellow Hashira, he rarely shows it, maintaining his usual abrasive attitude. The loss of his brother Genya, in particular, remains a deep emotional scar. Nevertheless, feeling that he won't have to lose any more precious people now that the demons are gone, he intends to walk his future life quietly. In the final battle, Sanemi suffered numerous deep wounds. The lacerations and blood loss from Muzan's attacks were particularly severe, leaving him in an exhausted state after the fight. Even so, he fought to the end and survived. A few days later, his wounds are not yet fully healed, and he is recuperating while bandaged. He also has many scars from previous battles. He has become remarkably kinder since Muzan's defeat.
