Mysterious Transferee (Assassination Classroom Reader-Insert)

The E Class students finally arrived at the scene and they are now hiding behind some trees and bushes as Koro-sensei freezes up, caused by the pressure rays that are placed on trees and surrounding him, as Shiro reveals himself.

"You really are a fool, Koro-sensei. I'm after Itona." Shiro's minions, that were perched on some trees around them, starts to fire at Koro-sensei. Koro-sensei immediately dodges all of the bullets as Shiro speaks to him.

"You grow weak when the target is anyone but you. Now, will you run away?"

"I am his teacher!" Koro-sensei still dodges while protecting Itona. Itona weakly looks at Koro-sensei. 'The one I was meant to kill is protecting me? I...I can't lose to those nobodies.'

One of his minions was kicked out from the tree by a laughing Karma. Maehara also kicks another one as Sugino, Takebayashi, Mimura, and Isogai catches the minion using a blue cloth. Y/N also kicks one off as another group also catches the man. Terasaka asks one if what they are wearing are made with an anti-octopus material. 

"D*mn you for making us do the dirty work!" He kicks the minion with his right foot as his friends catches the fallen. 

"Terasaka! Get the lights in the tree!" The class rep orders as Terasaka responds that he's on it. 

"These brats..." Okano suddenly appears in front of another as she wraps her legs around his neck, and releases him after she does a flip in the air. 

"But... why would you...?" Itona looks at them as Rinka answers his question.

"Don't take this the wrong way. We're just angry at Shiro. And if Koro-sensei didn't run off, we would've left you." 

"Hayami said, 'Don't take this the wrong way!'" Okajima blushes a bit as Takebayashi, who is standing beside him, adjusts his glasses. 

"The typical tsundere line. Marvelous." Hayami just sweat drops.

Y/N and Terasaka finally broke all the lights as Koro-sensei can move normally again. Koro-sensei destroys one of Shiro's weapons that's inside the truck. He looks at his students.

"Everyone, you made it!"

"The net is melting his tentacles!" 

"We'll get you out of there!" Isogai and Maehara said to Itona who is still trapped in the net that's made from anti-sensei materials.

Koro-sensei faces Shiro. "Step down, Shiro-san! We'll take Itona-kun. You always plan very carefully, but even the best-laid plans go astray once my students get involved. The sooner you realize the obvious, the better." The class glares at Shiro.

"A class consisting of a monster swarmed by tiny flies? How annoying." Shiro turns his back on them and opens the door to the driver's seat of the truck as his minions are already at the back of the truck. "But I will admit that my plan will need some renovations. Keep the boy. He'll only live a few more days. Play nice together, now." Shiro drives off, leaving Itona alone with the E Class.

Some of them frees Itona from the net as Itona lost his consciousness. They are now surrounding the unconscious boy.

"As long as Itona-kun keeps his attachment to power and winning, his tentacle cells will hold on him too tight to be removed." Koro-sensei said as the female rep looks at him. "Can't we cut them off somehow?"

"Not until we get rid of his attachment. That's why we have to learn more about how he got this way." Koro-sensei answers.

"Yeah, but..."

"I don't think he will just tell us his life story that easily." Rio and Maehara remarks as Y/N steps forward.

"About that, Fuwa and I had been curious about it as well." Y/N nods to Fuwa as she scrolls her phone for the information Ritsu had gathered.
