The Lost Moon Era

【No female lead/ensemble/hardcore combat】 At the stroke of midnight, the world does not enter January 1st but instead falls into an extra period of eternal night called the '13th month'. The sky turns into flowing indigo, 99% of humanity freezes into pale gray phantoms, and only a few 'Night Watchers' remain awake, facing the monsters surging from the cracks. This is an annual war managed by institutions—with staffing, canteens, salaries, and unavoidable costs. Here, death is not the cruelest ending. Those who die in the '13th month' are completely 'erased' when the world resets on January 1st. Everyone—parents, close friends, lovers—will forget they ever existed. All traces of your life in this world are wiped clean as if erased by a rubber. Shen Yan, 21, a junior in college, awakens as a Night Watcher during his first New Year's Eve. He has no bloodline explosion, no hidden system, no destined power—he only has one ability others lack: he cannot forget those deleted by the world. He writes every name in a ledger he carries with him... When the whole world forgets, this ledger is the only proof that the deceased ever existed. 'Don't die in a hurry; I haven't memorized your full name yet.' — Description from novelcodex.org
