Given we now know 2 names: Tartaros and Elysium. The last apostle's name will probably be Asphodel, no?
Upload the final chapters already, they are out there somewhere.
That said, I am not sure if I really want to continue. I like most of the story and the art but.... It starts out as a nice story with a ML who doesn't really change much and stay a possessive bastard but has some nice elements. Suddenly, the story starts to disconnect things happen back and forth without any logic. The villainess is revealed then isn't then is and is killed. All to throw in some stereotypical tropes. As if that wasn't messy enough, let's go back to some original elements and just mix it all together and then start stretching it all but having the mains just moan about what they should and could do without doing it. Seriously stick to the pace instead of trying to delay what's necessary, oh and let's show again that the ML hasn't had much of a character development by showing of his possessive side again in the most unlogical way.
