It was explained that around 500 y.o. demon king starts to decend into madness, but if he is granted name he will live for thousand years longer so a span of 500-7500 years seems consisntent.

So, if Reene gives him a name, she's sent back home - end of story. If she doesn't, this world ends - end of story. Man, this is one steep, treacherous cliff we're hanging off. And poor Noel gets shoved back into the shadows again while the important shit is going down.
I'm sure the story will still somehow find a way to ship those two together be it in this world or her original world. These kinds of shoujo stories always end more or less the same.
@Nightwave Well that would be anticlimatic... It would basically be cheating in the ultimate world's final test ? @AlmondMagnum And that would be so hilarious if it actually happened! I can already picture, with the dukes wondering if they didn't screw up their sacred ritual with their legendary god-like demon king being named "Pochi" ?
