Also, the Rating Game committee might pull some cheap shit with the Issei vs Dulio match.

They might do what they did with the Rias vs Sona match: make up some rules that restrict Issei's team to make the match "more balanced."

Maybe something like "They can't destroy the environment," which puts Dulio at an advantage since he has such great control of his [Zenith Tempest] that he can use his powers inside buildings without causing too much collateral damage.
