Cao Cao was obvious and the second match can go either way. Now we know Vali vs Tobio in Dx 6(possible) or higher. Depending there's a good chance True volume 5 can be this year. If I had to guess between October and December. Its Ravel's turn so I'm guessing its about her family or its the next match on how she'll help Issei's team overcome the champion.
