The Heartless One

After getting basically kicked out of the city, after pissing on his ex-friend's sandwich and shoving it down his throat, killing him, Anti and Light start to search for a place to stay the night.
Along the way, they find a circus.
After the show Anti planned to leave right away with Light, until an 'accident' happened. Having to pay up for his actions and anger, Anti and Light are staying for a while.
After a while Anti finds someone, that was able to steal his heart, but the problem is. The guy that did it, literally doesn't have a heart. Better go find one.

Warning: A lot of swearing.
