Summary:

Niwashi witnessed the end of YGGRADSIL, and found herself, like so many before her, brought about to a new world for a new life and adventures. Unfortunately, she saw that she'd landed right next to Ainz Oal Gown, and wanted fucking nothing to do with those trolls. She begged someone to get her out of there. A goddess answered. Now she's in another world, tasked by a sketchy goddess to test out a new way to clear corruption and pollution before everything dies. Fun. MC is a kitsune, has the overlord setup, and she has a system focused on spiritual farming and cleansing that will be expanded over time.
