During his company break, our protagonist is unceremoniously stabbed by a random attacker.

The moment it happens, a mysterious announcement echoes in his mind:

《You have been defeated by another. Commencing elimination countdown.》

"Wait, I'm going to die?!"

At that very moment, his country becomes linked to another world.

What soon appears are invasive monster species that care for nothing but invasion and slaughter.

However, protagonist Goto is surprisingly positive, so he quits his corporate job, repeatedly engages in production and self-enhancement, and begins to learn how to lead a fun survival life in preparation for the apocalypse.
