I'm doing a crossover anime/manga project, and I'm creating a new kind of "Moonlight&

Could he be an ally of the benefactor on the Otherworld Front?

But what is he doing at this gathering of important figures who secretly protect humanity?

Could it be...

Hachiman remembered that Rosser had just said he really needed his help.

So, could he actually be his parents' adopted son? Is his true identity the posthumous child of the Heavenly Lord? Or the only son of the previous Demon King of the Demon Realm?

He possessed immense hidden power, and the man before him had recognized him and was trying to recruit him.

Or perhaps a world-ending crisis resides within him, and the fate of the world hangs in his hands...

Incidentally, he prefers the former to the latter.

That means Komachi wouldn't be his biological sister anymore...

(Kousaka Kyosuke: So what if she's your younger sister? Is this all the love you have for your sister, as a Chiba native?)

Hikigaya Hachiman.

I graduated from high school less than two years ago with chuunibyou (middle school syndrome).

There were once seven gods in the world. On the surface, he appears to be an unsociable middle school student, but his true identity is the strongest and most solitary god among the seven...

Forget it, forget it, that embarrassing history!!!

At this moment.

"coming!"

Roser stood up, looked at the somewhat hesitant boy at the door, and waved: "Over here, over here, Ayanokouji-kun."

Hear the words.

The figure finally stopped pretending not to see and resignedly walked over: "Good afternoon, Professor Rosser."

"teacher?!!"

Hikigaya's voice even changed in an unbelievable way.

He's a teacher. Isn't your principal afraid he'll ruin your students?

Kiyotaka Ayanokoji looked at him expressionlessly.

Invisibly.

Hachiman seemed to understand something, and his eyes immediately showed pity.

He was like this when we first met, and this guy in front of me...

"Alright, everyone, sit down. It's time to eat and replenish your nutrition. This place is expensive, but at least the food isn't too bad."

Rosser waved his hand generously, gesturing for the two victims to sit down.

"Wait, did I hear that right?"

But as Hachiman eagerly stuffed it into his mouth, his expression immediately calmed down, and he chewed slowly.

Knew it.

It doesn't justify its price at all.

That makes sense, since this is mainly a place for listening to music...

"So......"

Sitting at the other end of the table, Rosser's demeanor completely changed, as if all his wicked humor and frivolity had simply vanished as a disguise.

Solemn, earnest, with a majestic aura as if a mountain were rising from the ground.

"...Let me introduce myself, Rother..."

Gulu.

Hikigaya swallowed hard.

"...Chaldea High Investigator, Mage of the Celestial Department of the Mage's Association!"

What is the Magic Association?

Is there an association for magicians to study magic tricks?

But what is astrophysics?

And the name Chaldea sounds familiar... Wait, isn't that a ridiculous virtual reality game from a few days ago?

He turned his head to look at the new boy and found that the other boy was calm, obviously already knowing.

So, they're also companions from the other world?

"Yes, that's right..."

Rother chuckled, but the smell of battle emanating from him seemed to linger, as if he had fought a thousand battles and returned from the brink of death, making Hachiman almost unable to breathe.

Even Ayanokoji's pupils contracted slightly.

There's no mistake, this is definitely the atmosphere of a battlefield.

He had felt this before from the veterans who taught him how to use firearms, but this was the first time it had been so intense, so tangible.

(Rother: Guess what I'll play now that you've been given 100% realistic simulation?)

"...The story in that game is all true."

"Is it all true...?"

Hikigaya's pupils contracted slightly as he felt a shiver run down his spine.

The story in that game is all about the destruction of the world.

Every time that ritual called the Holy Grail War is held, the world faces a death sentence.

Volume 1: Chapter 29 Lostbelt Invasion!

There are those who deeply love humanity but believe humanity is beyond saving and want to burn human history.

Some people pursue peace and create a grand illusion to let everyone dream together.

Some feel the human world is too dirty and want to destroy humanity to create a new kind of human...

The various world-destroying tricks are so elaborate they make people dizzy and overwhelmed.

In the past, he wouldn't have believed a single word; he was a staunch atheist.

But this atheist almost died just now!

I almost got killed by a monster!

It was as if she could read his mind.

Rosser suddenly asked, "What do you think that thing was?"

Hachiman was taken aback and tentatively asked, "An evil spirit?"

just?

Evil spirit?

Kiyotaka Ayanokoji, who was trying to keep a low profile, was also taken aback and looked at Hikigaya with a probing gaze.

He was covered in sweat and his face was pale, as if he had overexerted himself.

So he was harmed by an evil spirit and then saved by Professor Rosser?

He wasn't surprised at all that his teacher could exorcise demons.

After all, the thing that almost annihilated him was far more terrifying than any evil spirit.

But what the teacher means is that the world also...

Thinking of the various hilarious and outrageous apocalyptic disasters in the game, Ayanokouji's expression suddenly changed.

It's fun in games, but not so fun in real life.

"No~"

Rosser said softly, "That kind of thing isn't just a simple evil spirit."

"A strange story?"

Kiyotaka Ayanokoji's voice trembled.

"It's not that bad yet."

Rosser shook his head: "It can only be considered a derivative of some kind of ghost story."

Hachiman looked completely bewildered.

what are you guys saying?

He and Ayanokoji each only knew half of the information.

Rosser glanced at him.

"Tell Ayanokouji how you encountered that thing."

soon.

Hachiman recounted in detail his encounter with the evil spirit.

It is said that ordinary people cannot see it at all, but evil spirits repeatedly verify whether they can see it or not, as if there is a rule that cannot be harmed if it cannot be determined, and there is not just one or two such things.

Along the way, Hachiman vaguely saw parks, shopping malls, convenience stores, schools, etc., almost everywhere.

Ayanokouji's face had turned ashen.

Pit father ah.

Besides ghost stories, there are ghostly things everywhere in this world, and seeing them almost always means certain death.

Who can guarantee that Professor Rosser will be able to save them at the crucial moment next time?

"Don't panic..."

Just as the two were starting to feel relieved, Rosser paused for a moment and continued, "Panic won't help, and those kinds of evil spirits generally don't have the same kind of coercive power that Hachiman faced with that one."

Of course, some evil spirits also possess the ability to forcibly cross the boundaries between two worlds.

Hachiman, on the other hand, seemed to have come to terms with it first, or rather, given up: "Mr. Rosser, are you implying that the end-of-the-world risk for our world is evil spirits and ghost stories?"

"Evil spirit?"

Under their gazes, Rosser scoffed, exuding an air of domineering arrogance: "You dare to challenge me?"

Before the two could ask any further questions, he simply pulled out a stack of documents and pushed them across the table.

Do you really think that ghost stories are native to this world?

What do you mean?

Hikigaya took a look and his pupils immediately contracted sharply.

"That can't be..."

Ayanokoji Kiyotaka's hand trembled slightly.

This information is very simple.

It's just some files.

Archives of various events from the 1970s to the present.

In August 1972, the Black Hole opened, connecting two worlds. A twisted entity called the "Stand" descended upon Mount Yomi...

In July 1994, the Black Hole opened... A twisted entity known as the "Grim Reaper" descended upon Beika Town...

In 2001... a monster that resembled a human but fed on humans appeared...

In 2005...

In 2024..., a giant at least fourteen meters tall descended upon Saitama Prefecture, causing seven deaths. After being killed by local police, it turned into steam.
