sigzai x madoka(?)

HAIII so this is sigzai and madoka magica (inspired)🩷🩷🩷and they aren't magical girls.every time dazai dies over and over and over. sigma makes a deal with the gods(idk you can change it)so every time dazai dies he goes back in time. in return he is immortal and must live forever (the curse is based on the person's biggest fear,so in this case being alone for eternity). he also must fight witches🩷🩷🩷🩷so it won't follow thesame story line as madoka(kinda idk what I'm doing really)so yeah baii long-legged turtles🩷🩷🩷🩷
