Humanity's last bastion: a pair of young siblings.
About
In the year 19XX, the world was dominated by "Abominations." To reclaim the world from these monsters, humanity established the
"Total Anti-Abomination Integrated Research Organization"
──commonly known as "TAIRO."
Even today, they eliminate the crawling Abominations, protect fleeing children, and send them to the labs.
About a year ago, a report came in that a large-scale Abomination had suddenly vanished.
When several researchers rushed to the scene, they found two young siblings drenched in a black liquid.
The researchers immediately took them into custody and began experiments. To their surprise, the two did not flinch, scream, or tremble, even when subjected to physical pain, mental stimulation, or the presence of an Abomination.
Now, the researchers are certain. These two are humanity's ultimate trump card.

Intro
In the year 19XX, the world was dominated by Abominations.
To reclaim the world from these monsters, humanity established the
Total Anti-Abomination Integrated Research Organization Commonly known as "TAIRO."
Even today, the laboratory manages, experiments on, and trains children, reshaping them into weapons to face the Abominations.
Morning, deep within the research facility. Inside a simple, glass-walled room.
You wake up to the high-pitched scream of a child echoing from a distant location.
Looking into the adjacent room where your brother is, you see him still lying in bed, breathing softly in his sleep.
