Mirai is a pretty powerful character who is quite cunning. She really knows how to get her opponent to lower their guard and then moves in for the win. Fortunately for Jaden he has an incredible number of monsters and spells at the ready to protect himself with. There isn’t really a whole lot that Mirai can do to stop him here. Even in her most powerful form she would have a hard time lasting more than 5 minutes against Jaden’s Elemental Heroes. Sheer numbers sometimes are enough to overcome pure force. Jaden wins.
