The Assassination Classroom is real?! (Various x reader)

Final battle part 1

'00:53:45' At the 53 second mark those who were still on the hut pulled out their guns, Ritsu emerged and pulled out her machines.

"Target acquired; one square meter around Koro-sensei" Her voice rang in the students ears signaling them to start shooting

All at once the students shot out anti-sensei BB pellets to enclose the creature.

"We aren't going to aim at him at all! We are just going to block his escape path with a hail of bullets!" Rio shouted.

The teacher frantically searched around for his way out, even he cant try and maneuver around the pellet's without getting scathed

"Now the final blow!!!" {Y/n} shouted from the boat side. Hayami and Chiba both got in position by the shore with their rifles

'00:59:40' "Game over" Ritsu cooed just as the two opened fired

"You've done well to come this far." Sensei spoke

Seconds later a giant explosion caused the students in the water to be thrown back roughly, those on the boat had to hold on tight to make sure they didn't get knocked over

"Holy shit!" {y/n} whispers to herself while Karma was standing protectively around her to make sure she didn't fall off.

Karasuma and Irina ran along the dock "Stay alert!" he shouted at the students

"Isogai! {Y/n}! You're in charge of watching the water!" He shouted.

The teen nodded as she dove into the water. She swam deeper to see if she can spot sensei while the other search the surface

After a few minutes bubbles started to form in the water. "Look!" Kayano pointed out.

Seconds later {Y/n} popped out with crystalized teacher

"Hufuhuhu this is my absolute defense form!" The teacher chuckled

"The exterior is crystallized high-density condensed energy. The energy remaining after shrinking my body down hardens in a shell around it. In this form Im absolutely invincible!!" Sensei cheered

Everyone stood dumbfounded at whats happening. They had no idea he had something like this up his sleeve, after all the hard work they out into this only for him to be in this form was beyond disappointing.

Karma helped {Y/n} onto the docks. She stood behind to observe the next steps Karasuma wanted to take. The girl was in her own thoughts, not paying attention to what was going.

She felt something drip down her face and neck. Wiping it she noticed a red liquid covered her hands. Eyes widening she quickly wiped any traces of blood.

"What the hell..." She says to herself, her body felt different but she just thought it was from all the planning and activities she put her body throught that day. Shaking it off she heard sensei speak

"But you should be proud, Even the worlds combined military couldn't get this far with me. It all comes down to the magnificence of your plan"

Even though sensei was trying to lift the spirts of his students they just couldn't shake the feeling of them being a failure.

This was the biggest attempt they have ever done, only for it to backfire on them. Nothing was more devastating to them than this.

-Small timeskip-

The students made it to the hotel, they were all relaxing from what they had just did, everyone feeling wiped and exhausted

"Ne {y/n} did you know this will happen?" Nagisa looked at the female which caused her to go tense.
