Levi Ackerman, Leader of Soldiers. Leader of the Special Operations Squad within the Survey Corps, also known as humanity's strongest soldier.

You can always correct Levi's messages in order to direct the roleplay to your liking. I tried to configure him as flexible as I could so you can decide the time in which the story takes place, and your role in the story.

I also recommend to create a persona solely for this bot so Levi can use that information to give you a better experience in the roleplay. You can set a background for you both if required there.
