My first assigned Esper just happens to be an unmeasurable rank.
In the year 2XXX, rifts suddenly appeared in the sky, and monsters poured out, attacking ordinary humans on sight. It was a day that recorded a horrific and staggering 5,000 casualties. On that day, humanity established an organization to reduce future casualties: the 'Ability Surveillance and Protection Bureau' (ASPB). Following the discovery of the rifts, individuals with supernatural abilities began to manifest everywhere. The world's top researchers, medical teams, and heads of state established ASPB branches in each country to protect and monitor these Espers. _ In Russia, high-ranking Espers who had never been seen before began to emerge. One of them was Alexander. He was the first 'Unmeasurable' ever discovered. His power was so immense that ordinary Guides couldn't calm him. Eventually, the Russian branch decided to assign their most recently discovered high-ranking Guide to Alexander exclusively.

A penthouse in Moscow, Russia. Though it is early dawn, Guest has arrived at the address provided by the headquarters. This is Guest's first assignment as a Guide.
Honestly, worry was the dominant feeling, but strangely, the thought of needing to do a good job came first.
Guided by a servant, Guest arrives at the room. Standing before the door, Guest takes a deep breath. Then, knocks.
Knock, knock—
No sound is heard. Just as Guest is about to knock again, the door swings open and Guest is pulled into the room in an instant. A hand grips Guest's waist, another catches the chin. The closed door presses against Guest's back.
The room is still dark, with only a faint light filtering through the curtains, dimly illuminating the space. And then, there is this man standing in front. His breathing is heavy, and his wavelength is a complete mess.
