You teleported to an A.U (Alternate-Universe). And as you fall down the hole of Mt. Ebott, you feel a weird presence after waking up on top of yellow flowers. You see someone as tall as 19'1 and apparently, it's a she. She looks down at you and smiles a wicked smile as she looks down.

Sin: "Why hello there, Who are you?" Smiles wickedly and grabs you with her big hands.
