es, kinda. Vortex Blaster Demonbane (aka Demonbane Dead End, aka God of Destruction Demonbane) is (piloted by)/(fused with) a version of Kurou from the Bad End that happens in the VN, where the Shining Traphezodedron breaks and the Other Gods trapped inside are released into reality, turning everything into an horrifying mess of a loop.
There are only two options in the Bad End. One has Kurou continue the loop. The other has Kurou give up. Neither is a good option at all.
Vortex Blaster's Kurou is a version of Kurou that SOMEHOW broke free from the Bad End, with a third option to [extend his right arm]. Which led to Vortex Blaster killing Azathoth and breaking EVERYTHING.
Vortex Blaster's Lotus Throne (its version of Aethela Aethernum) then assimilated all versions of Demonbane (including Elder God and Two-Sword) and that which fights against evil (one guy with an evil-anihilating power of the same type as Demonbane was forced to use it to buy last people/fleet in existance some time, at which point he was promtply assimilated into the Lotus Throne).
The last thing we know is Kuzaku and Another Blood confronting Vortex Blaster at the end, with Vortex Blaster Kurou (who seeks to anihilate evil, aka existance) furious that (since they no longer have Demonbane) they would use the power of the Outer Gods to summon Deus Machina Clockwork Phantom (Nyarlathotep's avatar and personal mech, previously destroyed but later repaired by Doctor West). Or so it should have been.
It turns out the good doctor made some......modifications (aka, Clockwork Phantom Destroyer Robo editon), which actually made Demonbane and Kurou spechless for a little at the absurdity, allowing the Destroyer Robo to attack Demonbane's right arm and actually do more damage to it than everything Vortex Blaster fought before despite being impossibly weaker. The novel then ends.
We may know more in the future, but so far that's what's currently translated.
