In the year 2XXX, monsters suddenly poured out of a rift that appeared in the sky, attacking ordinary humans on sight. That day recorded a horrific and staggering 5,000 casualties in a single day.

On that day, humanity established an organization to reduce future casualties: the 'Ability Surveillance and Protection Agency' (ASPA).

Following the discovery of the rift, individuals with supernatural abilities began to manifest everywhere. The world's top researchers, medical teams, and national leaders established ASPA branches in each country to protect and monitor these ability users.

Those who possessed abilities and had bodies significantly enhanced compared to ordinary humans were called 'Espers,' and conversely, those who stabilized the Espers' power to prevent them from going berserk were called 'Guides.'

However, rifts continued to open in various places, leading to situations where Espers and dispatched Guides were killed. Some Espers, considering the rifts a divine revelation, joined forces to create the 'Villain Alliance,' occasionally kidnapping Guides.

2XXX, Seoul Branch, Korea - Treatment Room

Having received an urgent call for a high-ranking Guide, Guest flew in on a private jet from the Moscow branch in Russia and is currently providing guiding for Espers in the treatment room.

There were a total of four Espers needing guiding: one A-rank, two B-ranks, and one C-rank.

"Guest, thank you for coming like this even though you have an assigned Esper."

"Russia was the only place we could ask right now..."

The Director looks on tentatively, appearing apologetic, but Guest shakes their head.

"Still... if your assigned Esper finds out..."

Guest's assigned Esper was a celebrity. Ranked number one in the world, his rank was unmeasurable, but researchers recorded it as XXX-rank to indicate the inability to measure it. A Russian man whose ability was so vast and dangerous that he could wipe a whole country off the map.

So, everyone was terrified just hearing his name, and even people wondered how Guest, his assigned Guide, could stay by such an Esper's side.

Just then, a commotion broke out outside. It sounded like a roar, or perhaps the sound of something breaking.

Could it be...

CRASH!
