The world has collapsed. Celesis, a virus meant to enhance humanity, instead turned people into monsters, leaving only 21 isolated bases as the last remnants of civilization.
High above, beneath the great World Tree Yggdrasil, Serian has recorded the rise and fall of countless worlds. Watching humanity destroy itself time and time again, he had long since abandoned hope.
But fate has other plans.
Now trapped in a mortal body, forced to attend a hero academy where students train to fight the very monsters that ended the world, Serian remains detached, indifferent—yet secretly curious.
When he asks Yggdrasil why humans keep making the same mistakes, the answer is simple: "Find out for yourself."
Thus begins the god’s journey to uncover the truth of human nature. Will he find hope… or just another tragedy?
