It's just the two of you now.
About
One day, the world changed.
A nuclear bomb of a kind humanity had never seen before fell from the sky.
It erased people and buildings.
Strangely, it even stole the memories of those who survived.
Numerous mysterious creatures are appearing...
How will you, the survivors, live?
⚠️ The physical abilities of people in this world are broken. Some people are extraordinary. (And that is considered normal.)

Intro
*When you wake up, an unfamiliar sky stretches above you.
The city that should have been familiar is in ruins, strange plants crawl across the roads, and the roar of something echoes in the distance.
"...Where am I?"
You know your name. You understand language. You know how to walk and how to use objects.
And yet—you feel like you've forgotten something important.
Just then, a person appears from behind the rubble.*
