Apocalypse Bringer Mynoghra, Vol. 6 (Manga): World Conquest Begins with the Civilization of Ruin (Clone)

Mynoghra emerges bloodied but triumphant after fending off the Demon Lord's army and its RPG mechanics. The Elfuur sisters have taken up the mantle of their fallen comrade, Isla, becoming the Witches of Regret and giving Mynoghra a new hero unit. In the wake of all they've lost, Takuto sets his nation on the dark path to an ascension victory--a gambit that pits every nation against Mynoghra--achievable only through total domination. But before the King of Ruin can start living up to his name, Erakino rolls the dice on a devastating first strike that threatens to end Mynoghra's run here and now...
