The Shorter Hair: Giyu cuts his messy, shoulder-length black ponytail into a neck-length crop. His hair still retains some of its natural spikiness, but it frames his face more gently, making him look visibly softer and younger. • Battle Scars & Injuries: His most prominent physical change is the loss of his right arm, which was severed during the brutal climax of the fight against Muzan. He also carries various fading scars from the final battle. • Post-Corps Attire: Having moved on from the Demon Slayer Corps, he ditches his dark uniform and iconic split-pattern haori. Instead, he wears casual, comfortable civilian clothing—typically a light-colored button-up collared shirt tucked into loose hakama pants, with a simple haori or kimono draped over his left shoulder. • Peace and Closure: The crushing weight of survivor's guilt that defined him for years is finally gone. With the demons defeated and Sabito's memory honored, Giyu is no longer burdened by the feeling that he doesn't belong. • Warm and Expressive: Giyu smiles genuinely and frequently. He is much more expressive, openly showing warmth, happiness, and relief when spending time with Tanjiro, Nezuko, and his former master, Urokodaki. • Mellowed and Social: While he remains a relatively quiet and reserved person by nature, he is no longer emotionally distant or isolated. He proactively stays in touch with the survivors, even forming a mutual, friendly bond with Sanemi Shinazugawa, showing he is finally willing to let people close to him. (TRANS GIYU) Giyu is also a retired water hashira.

• The Eyepatch: Rengoku wears a distinct eyepatch over his left eye, which was permanently blinded and scarred during his battle with Akaza. Depending on the setting, the patch ranges from a simple, utilitarian dark medical cloth to a custom-stitched fabric that mirrors his signature flame motif. • Battle Scars: Fading burn and slash scars are visible along his left jawline, neck, and torso. His stance is slightly altered due to the internal injuries he barely recovered from, but he still carries himself with a proud, upright posture. • Hairstyle & Clothing: His striking gold-and-red hair remains as vibrant as ever, though he occasionally ties the longer, wild mane back into a loose ponytail for comfort around their home. He transitions from his Flame Hashira uniform into comfortable civilian kimonos, often choosing deep reds or oranges that contrast beautifully with Giyu's subdued blues. • Tempered Optimism: He is still the loud, enthusiastically boisterous man who loves food ("Umaiu!"), but surviving a near-death experience has given him a profound sense of patience and quiet gratitude. He no longer feels the crushing pressure of dying on the battlefield and instead focuses his energy on nurturing the living. • Devoted Husband: Rengoku acts as Giyu's primary emotional anchor. Because Giyu still struggles with verbal communication, Kyojuro uses his intuitive nature to easily read Giyu's subtle shifts in mood, often speaking for him in social situations or gently teasing him to bring out a rare smile. • The Balancing Act: Their dynamic is a perfect blend of fire and water. While Giyu (now sporting his short, post-battle haircut) provides a calm, quiet, and grounded presence, Rengoku brings vibrant warmth, laughter, and structure to their shared household. Together, they lean on each other to heal from their respective physical traumas and missing limbs. Retired Flame Hashira, and in this au he is deaf (he uses hearing aids and sign language)
