Volume 1: Chapter 257 Intelligence from the Heavenly Guild, Reunion in Hell

In the back room, on a floor with an unknown floor number.

The dim fluorescent lights flickered overhead, and the musty smell seeped from the yellowed wallpaper, making one feel involuntarily irritable.

"Pfft—!"

An exaggeratedly wide black greatsword swept across like a whirlwind, severing in two a long-armed, faceless entity that lunged out of the shadows.

The black blood splattered on the wall, but was quickly absorbed before it could leave a trace.

Guts, the black-clad swordsman who had been wielding his sword, took a deep breath and flicked away the shavings from his blade.

Beside him, a skeleton knight riding a skeletal warhorse stood silently on guard, while the little witch Shrek gripped her staff tightly, sensing the movement of the surrounding air.

Horikita pushed up his slightly reflective glasses and looked down at the black ball controller unfolding on his wrist.

After briefly confirming the physical characteristics and score of this floor, I took out my special notebook and made a note in the floor file above.

Not far from him, the machine girl Shuvi was floating in mid-air.

“Confirmed that the surrounding entities have been cleared,” Hugh said expressionlessly.

"Thanks for your hard work."

Horikita nodded slightly, his feelings somewhat complicated.

To be honest, their original plan was to follow Clockwork Demon's footsteps to see what happened to this mysterious merchant and what his behind-the-scenes operations were like when he was offline as a member of the Heavenly Guild and not taking exams.

Unfortunately... plans can't keep up with changes.

Although it only took a little time when Gojo Satoru called them over.

However, when they followed the clockwork demon into the back room, they had already lost track of him.

'If I had been a little faster...maybe I could have made it.'

Horikita Manabu sighed silently to himself.

But he doesn't intend to waste time complaining.

Since we've missed our chance, we can continue searching for a new breakthrough in the back room.

Anyway, we'll meet again someday in an exam.

Subsequently, in this process of exploration, they witnessed many original worlds that had not been completely swallowed up and assimilated by the back chamber.

There is a modern world where steel behemoths battle Kaijus in the Pacific Ocean;

There is also a Digital World composed of data, evolving and devouring itself...

Every world is magnificent, yet it struggles on the brink of destruction, having no time to pay attention to the back room behind the door.

However, Horikita Manabu did not come away empty-handed.

Putting aside the fragmented technologies of the various worlds copied by the Machine Gundam, the discovery in the Pacific Rim world alone was enough to excite him.

After helping the military of that world kill three level-five Kaiju that broke out of the sea.

Horikita Manabu noticed the familiar green hourglass-shaped icon on the arriving mech, which was exactly the same as the one on the mysterious merchant from the beginning, as well as the symbol of the Craftsmen who appeared in the Chainsaw Man world!

After questioning, and combining the intelligence obtained by Hughie from hacking into the local database, it was found that...

Horikita Manabu's guess was correct; the other party was indeed from an organization called "Tian Gong Hui".

According to them, the Celestial Union is an interstellar, cross-species law enforcement agency.

He seems to jokingly refer to himself as a "plumber who repairs leaks," specializing in plugging all sorts of unusual cracks that appear in the universe.

That world, twelve years ago, was able to build a giant mech capable of resisting an alien invasion and stabilize its defenses with the technical assistance of a "plumber".

in this way......

'As long as the Heavenly Craftsmen are indeed active in various worlds, following the intersection of the back chambers will eventually lead to contact with them again.'

'If we were to actually meet them, given their modus operandi, it wouldn't be far from impossible to glean some confidential information from them.'

Horikita Manabu gathered his thoughts and made a suggestion to the group.

"Let's go, prepare to enter the next door."

Then, the moment he pushed open the wooden door in front of him and stepped over the threshold...

The salty, fishy smell of the sea waves disappeared, replaced by a gloomy and heavy atmosphere.

Horikita Manabu raised his head.

There was no sky above, only countless doors of various shapes, hanging upside down in mid-air.

Beneath my feet stretched an endless grassland, but the breeze brought only an eerie heat.

"Is this... hell?"

It is not the abyss of judgment after death as depicted in religious mythology, but rather a demonic realm born from human fear.

Aside from the strong sense of déjà vu brought about by the high-scoring red dots such as "Forgotten Demon" and "Hungry Demon" displayed on the black ball controller.

A large part of the reason is that...
