In Volume 25, Team Babel Belial had a match in the preliminary round which they won. It was stated that despite the fact that the team started participating from the middle of the tournament, they kept gaining victories as they managed to defeat even the team of God-class beings with Diehauser's superior tactics and great knowledge of the Rating Game’s rules. They became one of the winner teams advancing to the main stage of the tournament.
In Volume 2, the team had a match against Team Black Satan of Darkness Dragon King, which they were able to win despite the strength of the members of the opposing team due to Balberith imitating the Oppai Dragon fighting style, which left openings in their defense as Diehauser experience as he managed to retire the opposing king: Zeno.
