Demon Slayer: I Became a Demon and Went into Hiding, and My Fiancé Is the Water Hashira

[Fated Love Polygon] [Otome] [Demon Slayer: A Faithful Story Told Like an Otome Game] [Ensemble Growth] [Female Demon Protagonist] [Everyone Survives] [Strong Female Lead's Growth] Against the raging tide of their era, a group of boys hardened by suffering find equal acceptance in the heroine, and in turn develop feelings for her and form deep bonds. They support and accept one another. Everyone's feelings are unrequited, and their affections are left to fate rather than deliberately encouraged. The story is firmly rooted in the original Demon Slayer world. Its core values, the Hashira's mission, the demons' nature, and the distinction between good and evil all align with the original spirit. The characters' behavior and principles are not overturned. The original heroine is a half-demon, and the conflicts and moral choices all unfold within the original framework. The Hashira's duty to slay demons and their responsibility to the people always come before their personal feelings. There are no love-struck, out-of-character changes to the story; this is an earnest, serious narrative. Shen Miaomiao, a shut-in who prefers to laze around, transmigrates one day. Her entire family is slaughtered, leaving her as the sole survivor. She becomes a rare kind of demon who does not eat people, but sustains herself on human presence and recovers through rest and seclusion. Her only wish is to hide away in the mountains and live alone. She wants only to protect herself, with no desire to get involved in the killing or be caught up in fate. But disaster strikes from the heavens, and Muzan hunts her relentlessly. What she never expected was that fate had already bound everyone tightly to her. Time and again, she finds herself in mortal peril, forcing herself to face every challenge. From wanting only to protect herself, she eventually grits her teeth and shoulders the burden of keeping everyone alive. The Hashira of the Demon Slayer Corps silently protect her, drawing her into a subtle, restrained love polygon involving everyone. Note: 1. The heroine grows over the course of the story. 2. Everyone's feelings develop gradually, with no sudden affections. Every show of special favor has a clear reason behind it. 3. The writing leans toward a weighty sense of fate, with ensemble bonds and personal growth...
