Changes

[[Masquerade]] manipulates two boys, [[Kosuke]] and [[Takashi]], into using his [[Doom Card]]s against the [[Battle Brawlers]]. He tells them that if they defeat the Brawlers, he will reunite their friend [[MiuMui]] with her brother. Wanting to help their friend, the boys track down [[Runo Misaki|Runo]] and [[Marucho Marukura|Marucho]], who were at the airport picking up [[Alice Gehabich|Alice]], and challenge them to a battle. Meanwhile [[Dan Kuso|Dan]] is lost in the airport and runs into [[Makoto|MiuMui's brother]], who notices that he is talking to [[Drago (Dan Kuso)|Drago]]. The battle heats up between the two Brawlers and Kosuke and Takashi with the Brawlers not doing that well. Luckily, Alice, who is quite skilled in battle techniques, guides them to victory. It is unknown if Miu Mui is reunited with her brother, but Dan, who is annoyed that he missed a brawl, is reunited with Runo, Marucho and Alice.

In response to [[MiuMui]]'s plead to end the way the battle was being played (sending [[Bakugan ]] to the [[Doom Dimension]] ), [[Takashi ]] and [[Kosuke]] both return their [[Doom Card]]s. They was going to admit their loss and quit but later agreed with [[Runo]] and [[Marucho]] to start a new battle just for fun.
