Hunter Grai have given the Marukas a mission since that he can no longer stand their bugging. When the Marukas decided to listen to Hunter Grai now, Hunter Grai give them a mission to change the temperature of the Jarbon region. The temperature changes at the Marukas orders, at the form of the bubble. First, when they heated up the place with Global Warming the brawlers seems to be getting really hot to see what is going on with the temperatures set by the Marukas, then when they cool it down with cold temperature, the brawlers seems to be cold, so does everyone in Jarbon. As they know that they are the Marukas doing those kinds of crazy schemes, Kouchu and his friends went to Professor Shari to figure out what to do with the world's temperature.
