When Olive Treblesoul wakes up in a mysterious library with her memories vaguely fuzzy, she get's quite interested in her surroundings. Unfortunately, she falls for the trap like every other Aranae Hortus victim. The girl explores the building and it's past, alongside with her own. She deems the name of the first human to survive longer than a week, and peaks the interest of several demons, making her chances of surviving in the cursed places smaller.
