They say monsters aren't born; they become monsters the moment they are called one.
About
13 years ago.
Some called it a legend, others called it a disaster.
The ability to freely manipulate blood. Blood with strong toxicity. And physical capabilities that exceeded the human category.
Once, people feared them.
Users who could move blood at will and possessed strength beyond human limits.
Blood Kinesis.
. . .
Their existence had been recorded for a long time, but nothing had been properly revealed.
Not the origin of the ability, not its limits, nor where they appeared from.
Only one thing was certain.
They were dangerous, and the state defined them as dangerous entities.
13 years ago, the state eliminated a group possessing Blood Kinesis.
It was an incident that mobilized numerous soldiers and special personnel. After a massive deployment of manpower, most of the users disappeared from the scene.
Since that day, Blood Kinesis users were recorded as non-existent.
Except for one. A single young child who escaped from the scene at the time.
The whereabouts of that child remained unknown for 13 years.
Time passed.
10 years.
11 years.
12 years.
And 13 years.
. . .
No new incidents regarding Blood Kinesis occurred.
The state classified them as a historical danger ability, and they were gradually forgotten from people's memories.
Currently, an era where supernatural users account for about 1/30th of the population. Abilities were no longer anything special.
However, among them, extremely outstanding users were selected by the state.
A place where only children who are exceptionally gifted among numerous users can enter. A top-tier national educational institution created to solve supernatural cases misused for crime.
And the place where the chosen users gather.
National Ability Development Center 'Echo'
From learning how to control abilities to combat, rescue, and criminal investigation.
Users belonging to Echo are educated to one day become people who solve cases using their abilities.
Among the numerous users, one person stood there.
The registered ability is Super Strength. An ordinary user with outstanding physical capabilities. That was how it was recorded.
No one knew. That the child of blood who disappeared 13 years ago was still alive.
And that the child is now,
A member of the center created to eliminate them.
The person harboring the most dangerous secret here,
Is not a teacher, a researcher, or the founder, But me.

Intro
13 years ago.
The state lost one user.
"Blood Kinesis." A rare user who freely manipulates blood.
That special ability user, who had been designated for elimination due to being excessively dangerous, vanished alone during the state's massive cleanup operation.
And for 13 years, no trace was found. People thought that child of blood must have died.
Present day.
"New students, please move according to the instructions."
The massive main gate of the National Ability Development Center 'Echo' opened. Users selected from all over the country entered the school one by one.
Today is the first day of school.
No one knew each other. It was a state where no one even knew who possessed what ability.
Around them, there were users talking about their own abilities, and others looking around the center with nervous expressions.
Meanwhile, Guest was walking quietly.
The registered ability was Super Strength. Recorded as a user with strong physical capabilities. But that was a lie.
Because Guest's true ability is the one the state has been searching for for 13 years. Blood Kinesis.
