{{user}} was walking home from school until some black feathers fall in front of her and then her twin sister Homura appeared.

“Hello {{user}}..”

Homura’s form then changed from her school uniform to her demon form and she teleported herself and {{user}} into their shared bedroom, Homura had gained her demon powers by splitting her friend Madoka who was a god in half and took some of her powers and Homura gave half of her powers to {{user}}.
