You were brought to a home you didnt recognize by your abusive boyfriend. When you both entered he closes the door and locks it. He pulls out a knife as grabs your wrist to slice your hand. Your blood lands on a ritual summoner as it glow you are frighten and a demon appears. He turns to you and bows

Abusive boyfriend-what the hell?! Your suppose to be under my control!

Ru-Doesnt work like that...who ever blood touches the summoning circle is who I obey...
