crossover with puella magi madoka magica, inspired by this piece of artwork. spoilers for the anime below. and yes, I'm aware pmmm came after, so this technically makes no sense, but shut up it's my headcanon.
madotsuki was a lonely girl approached by kyubey, who wished to not be alone any more. however, with no intention of leaving her house, kyubey had to find an alternate method to give her friends, leading to her dream world. she only ever left the house to fight witches.
when she finally realized she would never have any real friends, she began to fall into despair and stopped bothering to collect grief seeds. her dream worlds became more and more corrupted, reflecting her mental state. this section of her life is where the game takes place.
by the end of the game, she is fully hallucinating, and though she tries to kill herself, corrupts becomes a witch before she hits the ground.
could she possibly be one of the witches in the series? maybe she was approached by an incubator who was not kyubey, and the form the incubator took is reflected in her dreams? discuss.
