After being picked by Ha Yura as one of her teammates, he was elected as one of the initial participants, as a Defender, in the game of "Crazy Yellow Ball". In the first round, Baam was able to pass him after freezing him, which took him by surprise. In the next round, he watched as Yura overcame Baam's reverse-flow control and then bragged about her power but was killed when she threw him the ball as it entered into "Crazy Mode" and exploded while he was holding it.
