I still love this crossover · 3:17am Oct 14th, 2020
Basically, Guts from Berserk saves the cursed Magical Girls from Puella Madoka Magica.
In Puella Madoka Magica, the girls make a Faustian bargain with an alien being for a single wish, but in exchange for this wish they are forced to kill Eldritch Abominations they deem as "Witches".
