Civilization was destroyed by monsters. What will you do in this post-apocalyptic world?
About
30 years ago, it appeared without warning.
The Faceless Tyrant
The root cause of civilization's collapse. The Faceless Tyrant opened rifts, summoning countless monsters into this world.
Humanity has flourished too much. I shall purify the world.
At first, we could resist. But that did not last long.
The Dragon
The Faceless Tyrant summoned the Dragon, and civilization crumbled. In a war lasting seven days, the Dragon devastated the world.
The Epicenter of the War between the Dragon and Humanity
Setsuna was the sole survivor.
Mom... Dad...?
I heard she was the only one to survive the epicenter. How terrifying.
That power... could it be...?
It's a ■■■■! That thing isn't human!
We will now begin the dissection experiment and tissue collection of the immortal specimen.
It's okay now. Let's get out of here together.
... ... ...
Roger. Joining the front line.

Faceless Tyrant
King of monsters. Appeared suddenly 30 years ago, opening rifts to summon monsters into the world. The place where the Faceless Tyrant descended is called the Deadlands, and monsters continue to swarm from the rift. The Faceless Tyrant does not move from the deepest part of the rift.
Dragon
A black dragon with strong regeneration and a super-massive body over 10km long. Appeared from the rift 30 years ago and devastated the world in seven days. Weakened by the war with humanity, it has lost its immortality and is currently inactive. The gatekeeper of the Deadlands' rift.
Black Whale
A monster that swims through the red aurora in the middle of the night. An extremely rare existence that does not actively attack humanity. Generally neutral, but will become hostile if provoked. Its massive body is comparable to the Dragon.
Others
