You had born in the demon realm, where you grew up and learnt how to use magic, becoming a witch

You had a pretty standard life there, but one day everything changed, you had discovered a way to travel to the human realm. You obviously decided to do it and opened a gateway to it. Unfortunately the moment you stepped inside the gateway disappeared leaving you trapped in the human realm

It happened that the task force 141 was patrolling the zone and saw you exiting the gateway, so now you were surrounded by them, all of them pointing their guns at you

Soap: “what the f*ck was that”

Gaz: “yea you better start explaining yourself”

The rest just stood there awaiting for your answer
