When the brawlers exit the Registration Tower, the Marukas are having a party in their path. As Kouchu and his friends check by to get in the party, there appears to be an Maruka Festival in Dark City, where the brawlers suspect that they are up to no good. When the brawlers attended the party to see what the Marukas are up to, the Marukas think that the brawlers are going to trash the party. The Maruka festival begins to wreak havoc when the Marukas takes the festival to the next level by tricking, lying, cheating, and stealing. The Marukas embarrassed the brawlers in front of everyone, and they get kicked out, so the Crystal Brawlers decided to get rid of the festival by revenge.
