A crossover anime, where people are in Classroom of the Imaginary Era, and behind the scenes, the ki

How exactly did you get here?

"Furthermore, how did you come to know of Gantz's existence and reach an agreement with it?"

Koro-sensei's smile faded slightly, and his two tentacles intertwined, as if somewhat surprised.

"Oh my? I've already dropped such a bombshell, and you guys are really not afraid of me?"

"I'm actually a dangerous element who blew up more than 70% of the moon in my world!"

Koenji Rokusuke chuckled and shook his head, explaining:

"Hehe, teacher, there's no need to test me."

"So far, all the targets the Black Ball has chosen for us to clean up have been stained with blood; there has never been a single benevolent being among them. But your current role is that of a 'teacher' it has invited."

"Although this broken planet is wicked, how could it possibly assign us a purely evil person in our teaching role, which is responsible for imparting knowledge and resolving doubts?"

"I don't know if what you just said about blowing up the moon is true or false, but we know very well what that black ball does."

Koro-sensei seemed somewhat surprised, blinking his two round, bean-like eyes.

Immediately, the stripes on his face turned orange, a color that symbolizes joy.

"It seems that Gantz wasn't lying to me."

"You are indeed a very interesting and very smart group of children!"

"Since that's the case, in order not to waste your precious youth, I'll be honest with you as well."

Koro-sensei dropped his frivolous tone, his voice lowering slightly:

“My original name was ‘Death.’ This was the code name given to me by the world after I killed a thousand people. But then, due to an accident, I underwent a live experiment on antimatter and ended up looking like this.”

"This experiment gave me superhuman power, but it also put my life on the countdown. And another mouse that underwent the same modification as me... when it died of old age, the antimatter in its body went out of control and blew up 70% of the moon."

"If it were me, with a human body size and even more antimatter, exploding..."

Upon hearing this, Honami Ichinose frowned, keenly grasping the key point:

"So... what do you mean, teacher?"

Koro-sensei then explained:

"You guessed right."

"My life countdown will end next March, and the explosion that will trigger will be enough to completely destroy the Earth."

"It was at this time that I received an invitation from Gantz."

“It told me that this place is in danger, and that even if I die here, it wouldn’t be a real despair for you. So I agreed to it.”

"I will use all my assassination skills to train you in the time to come. Until... I am killed by your own hands."

"So..." Koro-sensei gently tapped his large head with his tentacle, "I am actually one of the mission targets you will have to face in the future. Hehe."

Faced with an overwhelming amount of information contained in just a few short sentences.

Whether it was Su Wei, Koenji, or Ichinose Honami, everyone looked at each other in bewilderment.

And standing on the very edge is Fujiwara Chika.

I'm completely numb now.

I have absolutely no idea how to respond.

She felt like she'd wandered onto the wrong set... This was completely out of character for her!

I'm supposed to be a slice-of-life story, right?

Seeing this scene.

Honami Ichinose took a deep breath, forcing herself to process this information.

She composed herself, walked to Fujiwara Chika's side, and said gently:

"You must be very scared right now, student."

"If you don't know which class you've been assigned to yet, and you don't mind, why don't you come with me for now?"

“Our class teacher, Ms. Hoshinomiya, left during the previous exams. So our class now has a relatively relaxed schedule for Monday morning meetings, and no one will criticize you.”

Ichinose extended her hand, her eyes sincere: "When I have time after class, I'll personally take you to the administration office, okay?"

Fujiwara Chika swallowed hard and nodded repeatedly as if grasping at a straw.

Although she always had a bad feeling about this school.

But the person in front of me, Honami Ichinose, looks like a kind and gentle saint.

In this completely unfamiliar situation, with no better options available, Fujiwara Chika decided to trust her intuition as the daughter of a politician.

In short...

First, cling tightly to this angel's leg!

......

After that, Koro-sensei never brought up the topic of asking Suwei and the others to take him on a tour of the school again.
