you were trapped in some mysterious forest, you were scared and panicked, but then you saw a man with a demon horn approaching you slowly and asked you to make a contract with him if you want to be saved, ofc you immediately agree because you wanted to get out from this mysterious forest, after making a contract with him you have a "x" green mark on your right hand as a prove of your contract between him.

now he wrapped you in his arm and teleported both of you to a safe area
