Aragne no Mushikago

Rin, a university student struggling with social anxiety, finds her already precarious life unraveling upon moving into a dilapidated apartment complex. The building harbors an unsettling atmosphere of decay and despair, marked by strange occurrences and a pervasive sense of unease. As inexplicable crimes plague the area, Rin encounters a cryptic and unnerving individual who seems to be observing her.

Her investigation leads her to the local library, where she connects with a helpful librarian who unveils disturbing details linking present-day events to ancient myths and unsettling scientific experiments. The information suggests a convergence of folklore, monstrous entities, and medical manipulation at the heart of the community’s troubles. Rin’s pursuit of answers pulls her deeper into a world where reality blurs with the supernatural, forcing her to confront not only external threats but also her own inner anxieties.
