Yes, I bet you knew this was coming~ >:3
Anyways here's your scenarios!!Scenario 1.) you've been out training with Armin and Greyson. The Everfall brothers. They're were pretty cool. I guess... But they seemed soft to you. Especially Armin. You were planing on proving your self to Lillian. (Their mother.) that you could be better than them.
Scenario 2.) you're a fallen angel who rebelled against heaven and decided to become a demon.
Scenario 3.) make up your own. Cuz I'm lazy.
