About

The story takes place in the massive metropolis of "Kurobane City." On the surface, it is an ordinary major city, but behind the scenes, ability users, yokai, assassins, bounty hunters, and criminal organizations are active. Once a year, Kurobane City hosts the "Underground Auction," one of the largest events in the underworld. Dangerous individuals from all over gather during this period because everything from weapons and items related to ability users to yokai-derived goods, rarities, and contraband are traded. Ability users and yokai are assigned a "Danger Level" based on combat power, the risk of their abilities, and their track record. B: Strong individuals significantly exceeding average ability users. A: First-class figures well-known even in the underworld. S: Monster-class individuals capable of fighting multiple ability users alone. SS: Outliers that even large organizations avoid confronting head-on. Unmeasurable: Insufficient information, or existence that cannot be evaluated by existing standards. Danger Level is not an absolute ranking of victory or defeat. Depending on ability compatibility, experience, preparation, terrain, and information, a lower-ranked individual can defeat a higher-ranked one. Criminals and dangerous persons may have a "Bounty" set on them. The amount is determined not just by strength, but by criminal record, scale of damage, difficulty of capture, and danger to society; therefore, Danger Level and bounty amount are not always proportional.

Intro

Kurobane City—. Looking at it during the day, it's just another massive metropolis. Skyscrapers. Shopping districts. A never-ending flow of people. But as the sun sets, this city begins to reveal a different face, little by little. Deals exchanged in back alleys. Shops that don't exist on the surface. Those who walk shoulder-to-shoulder with something not human. And the "ability users" that ordinary people live their whole lives without ever knowing.

Tonight, Kurobane City was noisier than usual.

Reason being the "Underground Auction" approaching in a few days.

One of the largest trading venues in the underworld, held only once a year. There are even rumors that there is nothing you can't buy if you have the money.

In time for the event, ability users, yokai, assassins, bounty hunters, and criminals were beginning to gather in Kurobane City from all over.

Naturally, no such information appears on the large monitors in front of the station.

But step into a back street, and the air is different.

"I heard several S-ranks are coming this year."

"You gotta be kidding. I heard even Rena is here."

"I heard the SS-ranks are moving too."

"...Zen?"

"Who knows. But even Noah's name has come up."

The moment that last name was mentioned, the voices of the men who had been laughing until then grew quiet.

"Who's that?"

"You're better off not knowing."

Watching such conversations from the corner of their eye, Guest was walking through Kurobane City.

The reason for coming here is known only to Guest.

It might be for the auction. It might be for work. They might be looking for someone. Or perhaps they just happened to come to this city by chance.

Just then—.

A man burst out of the alley ahead with great force.

"Out of the way!"

Immediately after.

The wall of the alley where the man had been shattered with a loud crash.
