After towers appeared all over the world, so many people died that it became impossible to keep count.

The situation was hopeless.

Governments collapsed, and currency lost all value.

From the towers, mysterious monsters poured out endlessly, massacring unarmed civilians.

Perhaps because of that, the survivors began to act with a single goal: survival.

But that didn’t mean all hope was lost.

At the same time the towers appeared, people began awakening to various abilities.

These individuals survived the catastrophes caused by the towers and gradually grew stronger.

People with superhuman physical abilities appeared, as well as others who could wield magic straight out of a fantasy novel.

Myself included.
