Frieren's Mini Anime 'Magic of ??

Magic that Removes Stubborn Oil Stains (1x6)

Air date: Jan 10, 2024

Sein has the idea of using the spell for profit by charging people who need tough oil stains removed from their pots and pans. However, because they offer to clean the first pot or pan for free, everyone only brings one pot or pan, and it ends up being volunteer work for Frieren.
