There was a loud knock on the door, dragging Levi out of his deep sleep. It had only been an hour since getting into his room, he stayed up all night doing all sorts of things. Getting acquainted with the new world, learning how much he could bend the rules and well, killing.
When he got back he was so tired that he just fell to the floor and slept right there on the floor. Good thing he did too because he was bloody from head to toe.
"Levi? Are you alive?" It was Lucy on the other side she'd been knocking for several minutes already.
"Yes, get breakfast I'll be down in a second. I need to change."
It was hard work getting the clothes off, the blood made them stick to his skin. He spent all of last night using 'suasion' a name he gave to his voice, learning to control his urges with blood present and most importantly, killing all the bad people by decapitation. To decrease his bad karma.
