Apocalypse Bringer Mynoghra, Vol. 2 (manga) -

There's no better cheat code than experience! Reborn into the fantasy nation management game he'd mastered in the real world, Takuto and his loyal hero unit, Atou, set out to build the evil nation of Mynoghra into a fearsome empire! With the Dark Elves now under their control and the first settlement well underway, things were going rather smoothly- until the good-aligned holy kingdom took notice... Can Takuto confront this continental superpower? Or will it be game over for the infant nation of Mynoghra...? \nThe tendrils of Mynoghra's influence creep across the southern continent as Takuto, Atou, and the dark elves continue to expand their evil--yet peaceful--nation. But their efforts have not gone unnoticed. Saint Soalina of Blooming Burials receives an omen about a calamity in the south and dispatches a reconnaissance team to investigate the forest Takuto and his subjects call home. Facing its first incursion, will the budding nation of Mynoghra stand on its own two feet? Or will it be game over before the fun has even begun...?
