YumeKiriLN
In a city where dreams bleed into reality, boundaries fracture without warning. Nightmares don't just haunt - they invade, twist memory, and leave people hollow.
Mermyna is one of the last true Defenders. Armed with Yumekiri, a fractured blade that severs lies rather than flesh, she repairs the seams between waking life and the dream-realm of Lumoria. She preserves what makes people human (even the pain) because erasing trauma only feeds something ancient and watchful on the other side.
But the incursions are evolving. Nightmares grow quieter, more efficient, almost consensual. People wake relieved, lighter... and strangely blank. Districts turn eerily calm, memories thin like worn fabric, and voluntary surrender spreads like a gentle plague.
Her rival Vaelor believes restraint is suicide - erase the weakness, optimize the city, let the system decide what survives. Mermyna refuses. Every cut she makes costs her blood and fragments of herself. Every time she holds the line, the thing beyond the boundary learns.
It no longer tests.
It negotiates.
A dark, philosophical progression fantasy about memory, consent, burnout, and the horrifying efficiency of peace. Restraint is killing her. Erasure is teaching something patient how to rule. When the system stops asking permission, Mermyna will have to choose - preserve imperfect humanity, or watch the world forget why it ever mattered.
