====[[Bakugan Battle Brawlers]]====He taught [[Makoto]] how to play the game along with Takashi. When he sees Miu upset that she hasn't seen her brother in a long time, [[Masquerade]] tells him if he can defeat the Battle Brawlers, he will reunite Miu with her brother. He brawls [[Runo]] and [[Marucho]] alongside Takashi but relinquishes the [[Doom Card]] when Miu starts crying. They then play them again and lose, though they were glad they had fun. Miu then gives them both a kiss on the cheek for trying to help her. He brawls with [[Darkus]] Bakugan.
