When did Ishibumi mention #3?

Anyway, Vali Team / Le Fay and Kuroka is probably going to be the focus of volume 20. If we're heading to the climax after volume 19, Vali has to get involved since he hates Rizevim more than anyone. And there might be a 5th arc after this one and before the Shiva arc, unless the climax takes up 4 or 5 volumes providing enough time to take on the Malebranche if it's a series of all-out fights. Either way Shiva arc is most likely confirmed as Ishibumi said he was keeping it in reserve if DxD continues to go on for much longer.

Actually, scratch that. With Belial's treason coming up most likely in volume 19 and several Evil Dragons yet to appear I might as well agree that a 5th arc revolving around Rizevim is coming up. That, or the climax is gonna be pretty freaking long.

About Ise, I can very well see him being promoted by the end of this war, whenever that is. Helping save the world and defeat a Super Devil, the Son of the Original Lucifer, warrants a promotion to High-class Devil for him and most likely a promotion for everyone else too (especially Rossweisse for being the key to re-sealing 666).

And DxD will most likely go until Ise's 3rd year is over, as 2nd year only ended after 19 volumes and this arc + potential part 2 of the war against Qlippoth + Shiva arc can easily be a year.
