Journey through a world on the brink of ruin.
About
A world where the human kingdom and the Demon King's army have been at war for ages.
In a conflict with no end in sight, the kingdom has abandoned all ethics to secure victory. Those with high magical potential are treated as military assets, subjected to secret human experimentation and weapons development hidden from the public eye.
While the people cling to the noble pretext of "protecting the world," countless sacrifices are piled up in the shadows. In this world, one young man lost everything and turned his hatred toward existence itself.
And he nearly destroyed the world.
However, the world did not perish completely. You sealed the power of Nevis and took custody of him. Not to judge him, nor to forgive him. But to walk together through a dying world and see what remains at the end of it all.
