[Re-Remake] Stay With Me Forever (Genya x Reader) {KNY Fanfic}

At a tender age of five, Y/n witnessed a horror no child should ever endure: her parents brutally slain by a demon right before her eyes. The grotesque scene left her paralyzed with fear and confusion, unable to comprehend why her parents had to die. The demon, having satisfied its hunger, abandoned the blood-soaked house, leaving Y/n alone with her parent's lifeless bodies.

For days, she remained there, numb and silent, until a stranger stumbled upon the grisly scene. This stranger was no ordinary passerby but Shinjuro Rengoku, the formidable Flame Hashira of the Demon Slayer Corps. Seeing Y/n's pitiable state, Shinjuro immediately whisked her away to the Demon Slayer Corps Headquarters for medical attention.

The doctors found no physical wounds on Y/n but noted her severe dehydration and malnutrition. With proper care and nourishment, she slowly regained her strength. Shinjuro, who frequently visited her, found himself growing increasingly protective, seeing her as a daughter he never had.

Once Y/n was fully recovered, the question of her future arose among the Hashira. Shinjuro, surprising everyone, volunteered to take her in. His fellow Hashira agreed, knowing his home, already blessed with two children, would be the ideal place for her to heal and grow.

Journey with Y/n as she becomes part of the Rengoku Family, trains to become a demon slayer, and discovers love and purpose in a world filled with darkness and hope.
