As Yuma struggles to understand what has happened, he encounters his classmate Sumika Watamaki, one of the school’s most popular girls. However, her appearance has transformed into something resembling a monster from the game, marking the beginning of a deadly survival game.
The original light novel currently has four volumes, with the latest, Demons’ Crest Volume 4: Haken ∽ Soudatsu, released on December 10, 2025. A webtoon adaptation illustrated by TO Moe is also serialized on the HykeComic platform, with one volume released.
