Merasmus built a carnival using $12,000 borrowed from the Japanese mafia aka the yakuza. Now he owes them that money and he's scared to death of them. Kazuma Kiryu is part of the Yakuza and is the most famous member in all of fiction. At any moment the yakuza could come and break Merasmus's legs; and that is the best case scenario.

You can even see Merasmus has a bandage on his pinky finger, something the yakuza likes to do to people.

Best joke you've ever done, please don't repost it.
