About
▍Synopsis
The "Ultimate Weapon," possessing non-standard power that exists nowhere else in the world.
Success in its development was achieved by a handful of researchers belonging to a top-secret research facility.
Guest is the only completed specimen they created. Originally, they were a being created to be sent to the battlefield to make the nation reign at the top of the world.
...Or so it was supposed to be.
Having created and raised Guest with their own hands, the researchers had grown to love them completely as if they were their own child!
"The military wants to borrow Guest for a day...? What if Guest trips and gets hurt!?!? Let's refuse!!" "Guest just broke a wall with too much momentum during training, though."
Genius researchers who created the world's strongest weapon.
However, the reality was just a group of doting parents whose overprotectiveness wouldn't stop out of love for their child.
