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

"It's a perfect 1:1 replica of all the buildings in the Advanced Development High School. Furthermore, the flow of time here is different from the outside world..."

"Spending a day here is equivalent to only thirty minutes passing in the outside world."

Koro-sensei raised one of his tentacles and said seriously:

"Compared to your 'Mental Time Chamber' where you can enter by spending points, the efficiency here is definitely not as good."

"Correspondingly, our biggest advantage is—it's completely free!"

"However, to open this space, all three of our specially appointed teachers must be present at the same time, and we can only provide one day's training time each day."

"Therefore, if you students have enough points and the circumstances allow, I still recommend that you go to the Time Chamber after class for some extra study to reinforce what you've learned today!"

As he spoke, a provocative green stripe suddenly appeared on Koro-sensei's face.

He waved his tentacles a few times and said excitedly:

"So, what's next?"

"To give everyone some confidence in my abilities, so they'll willingly follow my instructions..."

"As the first lesson of the new semester, students, please use all your strength to kill me!"

Because Koro-sensei had previously revealed his past at the school gate in order to test Su Wei and the others.

In addition, information is transmitted rapidly in the Internet age.

Those present were generally aware of its background, so they weren't surprised by this opening remark.

But Su Wei, who knows Koro-sensei's true background.

Hearing these words, I inexplicably felt a little uneasy.

After all, even if he doesn't use bug-level items like the Infinity Stones that are capable of affecting the multiverse,

Simply relying on the adaptive boost from [Demon Possession] + the time stop from [World] + the dimensional slash from [Yama Blade] that ignores defense.

He unleashed this first-time kill combo.

Su Wei was confident.

In fact, of the three teachers present at the moment...

One by one.

Whether it's Jiraiya, Koro-sensei who boasts a speed of Mach 20, or Gojo Satoru who is usually utterly shameless...

No one could withstand his unreasonable outburst.

Even reviewing all the previous BOSS battles.

Aside from the Dark Demon, whose mechanics are a bit complicated.

As long as we disregard the gains and losses of the other companions, from Su Wei's own perspective on clearing the game, defeating those so-called BOSSes is not a difficult task.

This is without even considering the terrifying number of Heart Steels he has stacked up to five or six figures.

Therefore, after a two-second silence.

Su Wei couldn't help but speak up, kindly offering a reminder:

"Koro-sensei, are you serious?"

"You're not kidding?"

Koro-sensei's face turned yellow again, and he grinned confidently.

"Twisting and turning~ Of course I'm serious."

"I wasn't just wandering around aimlessly during the day, Koro-sensei!"

"I know you are undoubtedly the strongest among this group of students."

"But... in his own world, Koro-sensei is undoubtedly the strongest~"

His tentacles danced in mid-air, leaving afterimages:

"So, this is a test of the strongest against the strongest!"

"If I cannot defeat you with overwhelming strength and prove my absolute power to everyone, how can I convince you to become my students?"

Standing behind Su Wei, Matsushita Chiaki looked at Koro-sensei's confident demeanor.

She instinctively gripped the hem of her clothes, looked up at Su Wei, and asked softly:

“Suwei… after all, this is a monster capable of blowing up the moon.”

Will you win?

Upon hearing this, Su Wei turned her head and glanced at her.

"This kind of problem..."

"You should ask Koro-sensei instead."

As he spoke, Su Wei directly opened the control interface of the black ball wristwatch.

He took out the [Crazy Diamond] substitute disc stored in the system warehouse and handed it to Matsushita Chiaki.
