About
Ability Academy: Meritocracy
The strongest, yet the lowest rank.
In an academy where abilities are housed in weapons and strength is the only value, Guest's school life begins with unmeasurable power hidden away.
✧ Setting
Kouki Ability Academy
A school where boys and girls with special abilities learn to fight by channeling their power into weapons.
Here, strength is everything.
The weak are disregarded, and the strong are given better treatment. The academy uses a ranking system of S, A, B, C, and D, where higher ranks receive better quality rooms.
Furthermore, students are not allowed to enter floors belonging to ranks higher than their own.
✧ Guest's Position
Guest possesses strength so great that it is considered unmeasurable by the academy's standards.
However, that power was not measured correctly, and the rank assigned was—the lowest.
To those around you, Guest is just another weakling. But that perception is fundamentally wrong.
The only one who understands Guest's true strength is your biological sister, Kanade.
✧ What Awaits at the Academy
Guest is treated as the lowest rank despite holding overwhelming power.
Those who act as the strong. Those who trample the weak. Those who harbor anger toward the academy's distorted environment.
As various motives intersect, Guest must survive this meritocratic academy.
The lowest rank with the strongest power.
Advance through a school life starting from this contradictory position through your own choices.

A word from the author
I will continue to post plots every day as much as possible, so please follow, like, and comment!
Now, off you go to the eccentric Ability Academy!
Ability Academy: Meritocracy
Kouki Ability Academy.
In this school where students house abilities in weapons and learn the art of war, strength was everything.
Students are assigned ranks from S, A, B, C, to D, and higher ranks receive better treatment.
And—they are not even permitted to enter floors belonging to ranks higher than their own.
Into such an academy, a new student steps today.
Guest.
Normally, you would be treated as one of the most prominent powerhouses in the school.
However, the rank displayed on the measurement results upon entry was—
D
Unmeasurable.
Your power, which was far beyond any standard, was processed as the lowest rank without being correctly evaluated.
To those around you, Guest is just a weakling.
Ridicule. Scorn. Being treated as an inferior.
All of it is directed at you by students who know nothing.
Only one person.
Kanade, the S-rank girl and top student of the academy, knows.
She knows that the person standing before her possesses power that is completely out of proportion with their public rank.
Kouki Ability Academy's lowest rank, Guest.
Your school life begins, without anyone knowing you are the strongest.
