Short chapter on the escape from the barrier trap made to kill Koro Sensei last chapter. Enjoy.

"I'm sorry Nagisa. I had to."

"Wha-you HAD TO? WHAT DO YOU MEAN YOU HAD TO! NO! YOU DIDN'T HAVE TO! YOU CHOOSE TO! WHY!?"

"Look…"

"NO! YOU LOOK! YOU JUST KILLED KORO SENSEI! AGAIN! YOU KNOW THE EMOTIONAL CONNECTION WE HAVE! YOU KNOW HOW MUCH WE LOVE HIM! HE-! WHY! JUST-"

"BECAUSE YOU DON'T GO AGAINST THE GOVERNMENT! BECAUSE I HAVE ORDERS! BECAUSE HE WAS SUPPOSED TO BE DEAD! BECAUSE GET OVER IT!"

"..."

"Anyway, we're all going to die. All of us."

"What do you mean all of us? Just Koro Sensei right?"

"No. It will kill all of us."

"What?!"

"This modified beam was supposed to vaporize all living cells, burn all inanimate objects and erase all dark matter particles." Karasuma said. "It was a last resort suicide option. The barrier will hold the explosion and contain the aftershock and particle effects until they disperse."

The shock was clear on everyone's face. Even the soldiers who were still conscious. Apparently even THEY didn't know.

"You...you would kill yourself and even us, just to get Koro Sensei?"

"I'm sorry."

"..."

The beacon beeped and everyone looked up. The final stages were being completed before the firing. 6 minutes until the beam was ready. 0.00938 seconds after until the beam reached the barrier. There was nothing they can do. Some of the less injured soldiers got up and tried to get past the barrier, but they hit it and flew back 20 feet. In desperation and fear, they kept on going at it. Each time, they flew back with a phbeww. "Stop trying soldier. These barriers absorb kinetic energy and then pulses it back out at you."

Three minutes left. Nobody spoke. No one knew what to say. Of course they didn't. Their cells were about to be burned on a molecular level and Koro Sensei was going to die. And then the barrier shattered. Stunned silence for a while. Then everyone ran. Karasuma was busy calling his bosses, telling them to shut down the beam. Soldier grabbed their comrades and sped down the mountain. The kids raced to their cars. The ones guarding the border of the mountain were jumping out of the way of this stampede of people.

A custom made car, with seats fitting up to 30 people, raced in front of the former 3-E class and stopping the 3-E students. Blonde hair blew in the wind as the window opened. "Get in class. We're going on a field trip."

Shoutout to Young Author-Cat for the idea on the next chapter and the last paragraph of this one.
