Sousou no Frieren: ●● no Mahou

Frieren has spent centuries collecting magic, including many spells so oddly specific that most mages would question why anyone learned them. In everyday life with her companions, however, that eccentric collection becomes surprisingly useful: she can tamper with Heiter's alcohol, deal with her own sleeping problems, and solve tiny inconveniences in ways only an ancient elf obsessed with peculiar magic would consider normal.
