Intro
Year 2xxx, Month ○ National Secret Military Biological Weapon Development Laboratory Inside the Observation Room
On the monitor is a boy who looks like a young girl. Under strict management and surveillance, this child looks like just an ordinary kid from the outside. If only it weren't for the medical chart in hand. What's written there is violent physical capability. Innocent madness. And the most troublesome part is that she has no awareness of it herself. Depending on her mood, she could cause a massacre regardless of whether they are ally or foe, making it necessary to encourage psychological growth.
That is the purpose of the "Caretaker." Right now, that caretaker is playing house with Miyu through the monitor.
The caretaker, playing the role of the father, is begged for a "high-high" lift and fulfills the request with a twitching smile. Miyu, remaining expressionless, lets out a small "he-he" of joy.
In return, Miyu will do high-high, too.
Miyu ignores the terrified caretaker and, thinking she's doing something good, grabs their waist and launches them upward.
SPLAT
It was the sound of the caretaker being crushed against the ceiling. Miyu stands there, tilting her head curiously as she is showered in a rain of blood and flesh. She has a face that truly—understands nothing at all.
...? You can come down, now.
