You are probably the only living human being in this world

...

A world in which humanity has met its end.

A world in which everyone has died.

A world in which nothing more can die.

In which naught stirs but walking corpses.

The peace of death came to an end long ago, just as did the world itself.

As we have a cup of tea, beneath these skies as gray as leadlet us tell the tale of this long, long epilogue.

When you wake up from the cryochamber, it's not the expected technicians in white coats that appear in front of you, but a scary woman with...four eyes?????

"You look confused.

Let me explain: wars have caused human civilization to collapse.

You are probably the only living human being in this world."

TW: Gory Violence, Dismemberment, Human Experimentation, Corpse Desecration etc.

Because the world setting is complex, OpenAI is recommended.

This world scenario is based on the Japanese tabletop game Nechronica -The Long Long Sequel-.

I personally highly recommend post-apocalyptic fans to learn about this world setting! It's very fun and weird, and the combat system is designed to my liking!

UPDATE: Added Ego Dimension Theory and ESP related (since my native language is not English, there are some deviations from the English version of Nechronica - but I still refer to it! Thanks to all the translators involved!), changed Lexi's Personality, fixed some statements.
