It just feels a bit early to write off Rizevim, the guys a Super Devil on par with Sirzechs and Ajuka, i just don't see Issei or anyone in DxD defeating him so soon.

Plus i kinda want it in a way like its a plan formulated by Rizevim and Euclid to unseal the Malebranche and have them serve under him. It would be interesting since the Evil Dragon armies are almost gone he'll need a new army....Wait.

Hmm Euclid unseals Malebranche, this could be something, maybe Euclid and Rizevim formulates this plan to unseal the Malebranche have them wreck havoc and chaos around while Qlippoth prepares the final preparation of unsealing 666. Yeah this could be good too. Not only Rizevim won't be the main villain of the fifth arc, we might have a chance to see 666 in a possible sixth arc.
