3rd Person POV:

All of class 3-E got into their positions around the lab and waited for Ritsu to give them the all clear. Ritsu was of course in charge of this to make sure everything was clear which now it was. Ritsu gave them the All clear and 3 groups went inside whil one stayed outside and started taking out any guards around the building.

The entire building was in a circle shape with a long hallway that loops around. Nagisa's group would have to go to the other end of the building to go though an elevator to the bottom level. Very inconvenient if you think about it. Nagisa thought to himself.

Karasuma went with the group heading away from Nagisa to take down the radio system. While Irina and Koro-Sensei went with the other two who ran as fast as they could to the elevator.

A few guards came out of their posts ready to take down the intruders. What they weren't expecting was a barrage of BB's sending them into a deep sleep. A few students stoped and tied of the Guards before catching up with the group again.

"Ok they have signaled for some support so group 4 get ready out there. You should be expecting 20 or so to arrive. Group 3 take down their communications fast!" Ritsu said over their phones. "Don't worry I took it down just now. No more talking or reinforcements." Itona said.

Nagisa had finally arrived at the elevator and his group instantly got in and headed down. "Be aware group one that at the bottom of the elevator their are 4 guards at each end of the hallway." Ritsu said. "Thanks for the heads up. Guess we can test out these smoke bombs." Karma said with a grin.

The elevator opened up and Karma threw out a smoke grenade hiding their presence. Each one of them stepped out and rained bullets hitting all 8 guards. "Obstacle one taken down. Now it's time to find Yanigasawa." Nagisa said. Ritsu pulled up a map on Nagisa's phone that showed where Yanigasawa was located.

As they ran down the hall they saw a man standing there. The same one that knocked Karma and Nakamura out. "You finally got here. Took you long enough. Listen even if you are a couple of kids I have a reputation to uphold so let's make this quick." The assassin said. "Didn't I already tell you that you wouldn't lay a hand on my students?" Koro-Sensei said as he approached the man.

"I'm sorry but you don't scare me anymore. I am the assassin know as death wish don't think your going to win easily!" Death wish said with a smirk. "Oh well this sure will be fun. The second highest ranking assassin in the world going against the reaper! How do you think this will turn out?" Koro-Sensei said with green stripes curving around his face.

"This makes sense now. I GUESS IM GOING TO HAVE TO KILL YOU THEN!" Death wish screamed as he injected the serum into his body with the intent to kill the reaper. "Go on ahead students he won't harm you now. He has his full attention on me." Koro sense I said as he got into a fighting position. "Let's begin your first lesson then shall we?" Korosensei's said as he charged forward.

Death wish swung the anti tentacle knife cutting off a tentacle. Not before being hit by a tentacle going Mach 20. After the first contact Koro-Sensei stopped for a second and grew back his tentacle. But to his surprise the assassin didn't move at all. And before he knew it he was shooting a barrage of bullets at him.

Koro-Sensei had barely anytime to dodge. He kept getting closer while dodging the incoming projectiles. When he went for the attack death wish grabbed his knife and cut a tentacle straight off.

Koro-Sensei instantly fell to the ground and knocked three tentacles against the assassins legs knocking him to the floor. Ok perfect know I need to knock him out Koro-Sensei thought. But before he could go in he had two tentacles get cut off instantly. And he had to jump back to regenerate.

When Koro-Sensei jumped back death wish instantly charged in with another attack ready to take him down for good. Instead he was met with a bright light that fired knocking him to the ground. Death wish instantly got up only to find The reaper in front of him with all tentacles grown back.

He was instantly thrown down again but this time he shot at Koro-Sensei who was charging like a bullet. He missed all shots and instantly got thrown upwards and fell straight back to the ground.

Death wish for up but his movements were slowing. Once he wobbly got back on his feet Koro-Sensei I was already there. He managed to cut off another tentacle but was instantly thrown to the ground with a tentacle plunging towards his face knocking him out.

For good measure Koro-Sensei grabbed several sleeping bullets with a napkin and launched them fast enough to make them work. He needed a break. So Koro-Sensei leaned against the wall and rested for a few minutes getting ready to back up his students

Mean while Nagisa with his group had arrived at the room where Yanigasawa was. "Kanzaki, and Sugino stay out here and keep watch. We're going in!" Nagisa said before he opened the door and charged in. Okuda threw a noise bomb making 4 guards look in its direction.

When they were distracted Fuwa and Nakamura shot them sending them straight to sleep. Nagisa and Karma ran foward and slashed two more guards knocking them out.

All that was left were two final guards. Okuda threw a smoke bomb while fuwa, and Karma went to the edges of the room and shoot the guards knocking them out.

One guard came from the roof surprising them all but was by Kayano who was safely In her battle pocket.

"H-Hey we can talk about this can't w-we?" Yanigasawa stuttered out. As the students stepped closer Fuwa and Karma got hit in the heads sending them plummeting to the floor. Nakamura and Nagisa tried to fight back but were hit in the heads knocking them out too. Even Kayano got knocked out after Nagisa fell on the floor.

"What an easy victory" the girl said allowed. Not before being attacked by a tentacle from behind sending her flying into a wall next to Yanigasawa. "Oh if it isint my guinea pig! Back for more are yo-" Yanigasawa was thrown into the wall before he could finish his sentence.

Koro-Sensei charged up to him and started unleashing all the rage he had against him knocking Yanigasawa unconscious. Koro-Sensei got up slowly with a sad grin after remembering Aguri's death at the hands of Yanigasawa. He looked towards his students and realized Nagisa and that female were missing.

He realized that that girl must be an assassin and is here to kidnap Nagisa. This entire raid was a trap. "Karasuma, and Irina lead your groups to the bottom level! Theirs an assassin who has a hold of Nagisa and is making a run for it!" Koro-Sensei yelled into his phone.

As the assassin ran threw the hallway with Nagisa in her arms. she quickly got surrounded by two groups of students. She quickly had to get out so she used a smoke and noise grenade and with Nagisa in hand climbed into the vents to get on the first level.

She hopped out of the vent and started making a mad dash to the exit. Not before being met with another group of students ready to take her out. "Give us back the little squirt or else!" Terasaka said with a menacing voice.

"Sorry but I can't do that. It's nothing personal just business!" The assassin said with a smile. She charged at Terasaka kicking him to the floor. Okano and Maehara went in for an attack kicking her but to no avail. Chiba and Hayami shot a barrage of bullets but the assassin quickly ducked and knocked them both over.

The assassin got up and finished taking down Mimura, Hazama, and Hara. She was heading out when she felt a sharp pain in here chest. She pulled out a mini BB and realized she just lost right at the end. "Sleep B...B?"

Kayano had gotten up and quickly shot the assassin knocking here out and saving Both her and Nagisa. Koro-Sensei came flying through the hallway Only to see group 4 the assassin and Nagisa all on the ground passed out.

Kayano slowly wiggles out of her battle pocket and told Koro-Sensei "Mission successful!".

————————

Yanigasawa the two assassins and all the quads were put under arrest and taken away. Of course Nagisa and Kayano got some revenge in the form of a whole lot of wasabi.

"Now then class you've all had a rough day. But most importantly you all did extremely well and deserve a celebration! So tommorow we who'll have a more relaxed class. But for now all of you should head home and get some rest." Koro-Sensei said.

A/N I realized I am suuuuuuuper bad at keeping track of time. If it helps the raid happened on Wednesday. Now then I'm going to go back and edit more chapters so as always tell me if I made any grammar or spelling mistakes and I'll fix them! Bye Bye!!!
