胸に魔石を埋め込まれた俺は、誰に復讐すればいいのですか？

This world is cruel.

Life is fragile, and the lives around us are constantly being lost.

I was born in a glass cylinder, floating in liquid.

Right, I was aware of myself.

A green stone was implanted in my body, and when I recovered from having fainted, everything around me had turned to rubble. All the glass cylinders other than mine had burst, and no one was alive.

A world completely devoid of living beings.

First things first, I wanted to get out of there.

All on my own, I went around the world, without knowing anything.

I have a peculiar constitution, and am denied my death.

Even so, I still wanted to be human.

Desperately holding onto life, continuously struggling despite my powerlessness.

As if to mock me, countries, armies, and magical weapons, all trample across the world.

And then, I lost my loved one.

That which was important to me, all of it, gone.

And so that’s why I decided to destroy the world.
