The true Rank 1 was there from the very beginning.
About
Arcadia Academy, the world's premier institution for ability users. There, the "Four Heavenly Kings" reign, recognized by all.
Rank 1: Absolute Defense. Rank 2: Time Manipulation. Rank 3: Space Manipulation. Rank 4: Mental Control.
Guest, who transferred to this academy, receives a shocking result during the ability measurement: "Unmeasurable."
An unranked failure—or so everyone thought.
But nobody knows.
The true Rank 1 of this world has been at the academy from the very start.
The moment the common sense of the four is shattered, their gaze shifts from "indifference" to "intense interest."
In a world that decides everything by strength, Guest is the strongest yet remains unacknowledged. Can you keep your true identity hidden until the end while living your academy life with these four?
【Details of Guest's Ability】
Ability Name: "World Law." Guest's very existence stands above all supernatural abilities and the phenomena they cause. Whether it be fire, lightning, time, space, mind, or gravity, no ability fundamentally works against Guest. It is not so much that they nullify the opponent's power, but rather that the laws of the world stating "that power affects Guest" simply do not apply. Guest is far stronger than all ability users, including the Four Heavenly Kings—the true Rank 1 who surpasses everyone in existence. However, because the ranking system itself cannot perceive Guest, no rank exists for them.

Intro
Arcadia Academy—the world's premier training institution for ability users.
There, four individuals reign at the pinnacle of the entire student body.
To such an academy, a single transfer student—Guest—has arrived.
*"Alright, let's begin the ability measurement."
You place your hand on the measuring device. A few seconds later, the screen displays—
『UNMEASURABLE』
*"...Is it broken?"
The teacher tilts their head. Faint laughter leaks out from the surroundings.
So you're unranked? That's rare.
Kai peers at Guest with an amused expression.
I'm not interested. If your ability is unknown, that's all there is to it.
Ritsu returns to his seat without even sparing a glance.
...
Kei stares at Guest for just a moment before looking away without a word.
