Chapter 18: Infiltration?! Let's make it assassin ways!

After the students finished changing their clothes to more comfortable one, the teachers ushered them to their destined car and ready to go to the said black hotel. The students getting more and more nervous as they getting near to their destination, well it's their first assassination without Koro-sensei after all.

As soon as they're arrived Koro-sensei star giving them a briefing, even though he had a little argument with Karasuma-sensei, in the end they still going in because of Koro-sensei words and the class already proofed their skills to Karasuma-sensei.

The students start to climbing the cliff, it made Karasuma-sensei and Bitch-sensei shocked, "Karasuma-sensei, we still haven't had a practice how to fighting an unknown foe in an unknown hotel. I know it won't be easy, but could you be our commander?" ask Isogai.

"As you can see, they're no ordinary students. You have a fifteen-member special forces unit at your command, don't forget about Ritsu, nurufufufu," said Koro-sensei

"Now, there's not much time left," continue Koro-sensei and finally Karasuma-sensei made a decision.

"Attention! Our objective is the top floor of the hotel at the summit! Our mission will shift from a stealth infiltration to a surprise attack! We'll use the same hand signals and link-ups from training! The only difference is our target! You have three minutes to memorize the map. We begin at 2150!" Command Karasuma-sensei.

"Aye sir!" replied the students.

When they arrived at the top of the cliff they're doing final checking for the hotel map. First, they can't use the elevator because it required a pass-card to use it so they must take the stairs, but the stairs is scattered throughout the hotel so they have to cover some distance on foot. From what Chiba said it look like a TV station and finally their mission started as soon as Ritsu opened the backdoor of the hotel.

On the first floor, meet with heavily guarded lounge that make them stopped and hiding behind the walls.

"There are more guards than I'd expected," said Karasuma.

"It'd be too difficult for us all get past," said Nagisa.

'Should only a few of us go on from here?' thought Karasuma-sensei, 'No, multiple enemies make it too risky.'

"What are you thinking about? Just go through," said Bitch-sensei suddenly.

"Eh?!" shocked the class.

"How are we supposed to make it past those guards?" ask Kimura, but Bitch-sensei just walking through them and look for the current situation.

"That's why, just go through," said Bitch-sensei and walk to the lounge.

The 3E's students see Bitch-sensei acting like a drunk person, the class can't hear the conversation clearly but they do aware that their teacher disguising as a pianist when she started to play the piano. As if she cast some magic, all the audience in the hearing range is captivated by her and not long after that she gave a code that she will be give them 20 minutes to go.

'What a beautiful teacher that we have,' thought Nagisa and giving one last glance to her English teacher.

With Bitch-sensei helping, now they can continue their mission to the next mission. Form what Karasuma explained, they don't have to worry about Irina because she one of the top honeypot master in the world.

Finally, they arrived at the third floor.

"Now, we're finally past the stringent entrance checks, we should be able to pose as regular guests," said Karasuma.

"Guests? How can we do that? Did they allowed groups of junior-high kids come here?" asked Sugaya.

"Plenty, from what I heard many spoiled entertainers and millionaires kids come, in the outside they maybe look innocent but behind their parents they're aiming for darker pursuit," Karasuma explained to them.

"Right! So walk around acting like those kids, looking down your noses at the whole world!" said Koro-sensei excitedly. Well, in turn out to be a total chaos and funny because the class don't know how to act like that. To be exact, the look more like a group of gangster rather than an arrogant rich kids.

"Okay, you guys can stop," said Karasuma and the class stopped their hilarious action.

"So, what should we do, sensei? As you can see, just now…," said Kimura.

"Nurufufufu, maybe Karma can give you an example, after all he's the most familiar with that kind of group," Said Koro-sensei and he look at Karma, "Is that right, Karma?"

His statement make the class give a curious look to Karma and the said red head just give him a sigh, "Well, if you say so, sensei. Now, let's continue," he said and suddenly the aura around him change.

He look more tall and refined, look like a whole new person.

'Whoa, he look like a whole new person,' thought the class.

'It's been a while for him looking like that, usually I only see him like this in his family gathering,' thought Nagisa.

"It's a good thing right, Nagisa-san?" asked Koro-sensei.

"Yes, sensei," replied Nagisa and give him a smile.

They started to walk and Koro-sensei warned them about the enemy, "Before that, we don't know our opponents face. He might even attack us while posing as a regular guest, we must proceed with plenty of caution," said him.

"Aye sir!" replied the class.

Meanwhile, Okuda and Takebayashi diligently treat their sick classmate. They give their classmate a compress in head to keep them cool and to avoid any brain damage form the fever.

"Sorry, Okuda… Takebayashi," said Sugino weakly.

"I-it's okay," replied Okuda.

Not long after that suddenly a group of man and woman with white coat come to their place. Look's like they're a medic group, but one person is really caught their sight with his vibrant green hair and the weird item that look like a piggybank in his hand.

'Who are they?!' thought the class.

"So, this is it, nanodayo," said the weird green person and look around at them.

'and what with that nanodayo?!'

"Who are you guys..?" asked Takebayashi.

"Did Akabane not informed you guys, nanodayo?" The green haired person asked back.

"A-ah, I remember you guys are the help that Karma called, right?" said Okuda.

"Yes, my name is Midorima Shintarou and this my lucky item for today from oha-asa is a piggy bank, nanodayo" said the now Midorima.

"Lucky item?! Why this guy is so weird?! Karma what kind of help did you get for us?!' thought Sugino.

'I-is he a tsundere? And lucky item?' thought the others.

The said person suddenly sneezing, "Looks like I'm must make someone suffered," with a evil glinting eyes and give people around him a scare.

"Can one of you give me an explanation, while my people is checking on your friends, nanodayo?" said Midorima.

"I can," replied Takebayashi.

"So, this virus will not spread, because Okuda and I are still okay even though already contacted with our friends who's been attacked by the virus for a while. It's likely transmitted orally, it's have to be mixed into food or drink or something," Explained him.

"I see, in conclusion this virus it's only for you all, nanodayo" said Midorima while corrected his glasses.

After done thinking, Midorima looked at his team, "Your job is to finished the antidote within 15 minutes and I don't want to hear any mistakes, nanodayo," command him.

"Yes, sir!" replied them and they started to work on the antidote.

"W-what?! Make an antidote in 15 minutes?! Is that possible?!" shocked Takebayashi.

"Of course, Akabane already give me an explanation before what I need to know how the virus is spreading and for me something like this is nothing, nanodayo," said Midorima.

"O-kay," replied Takebayashi.

"Speaking of which, where is Akabane? It's not like I care about him, I just want to know where he iwent even though he's the one who's calling me through Akashi, nanodayo," said Midorima again.

"H-he's in some kind business with the remaining person in our class, maybe he will be back around 15 minutes again," replied Okuda.

"I see, nanodayo," said Midorima and look a bit suspicious to them.

'What kind of a mess that you guys get to me in here, Akashi, Akabane?!' thought Midorima irritated at the two devils.

At the same time two red head sneezes.

In the infiltration group, they finally meet some problem. They finally meet one of their enemies.

"Terasaka-kun! Watch out!" warned Fuwa when she saw the man that walk right in front of them.

Fortunately, Karasuma have faster reflects. So, he can pull Terasaka dan Yoshida to behind him before the purple gas get them. He closed his mouth and nose with his hand and then he kicked the gas cartridge away from their enemy hand.

"Karasuma-sensei!" shout Kayano worriedly.

Karasuma jump backward after that and the gas started to disappear.

"Why can you tell? I show no bloodlust as I pass by. That happens to be my speciality, miss helmet-head," said the enemy.

"Because, aren't you the one who gave us our welcome drink?" said Fuwa.

"Then was it you who gave everyone that virus?" Asked Kayano.

"Your Evidence is pretty weak," said the enemy.

"No, Kayano is right. For today we ate and drink the same thing only in two times. One is the drink that you give to us and the second is on the shipboard dinner. But, with Okajima and Mimura who worked on video through dinner getting infected too it made the time narrowing to those daytime drink. And that means, the culprit is you!" explained Fuwa.

Her explanation made the enemy shut his mouth and the class praises Fuwa for her accurate detective deduction. But their happy moment just stayed for a while, suddenly Karasuma going down as if he doesn't have any power in his leg.

"I guess you guys successfully uncovered my identity and for introduction, my name is Smog," said Smog.

"But, aren't that already too late? Look at your teacher," continue Smog with a smug face, "My gas is very deadly one sniff and the enemy will fall like a living statue. Now, there's no way you guys can breakthrough from this problem. Negotiation have broken down. Guess I'll have to tell my boss."

His path blocked by Chiba, Kataoka, Terasaka and Isogai when he wanted to walk back, 'They're fast!' thought Smog and he observed the current situation.

'When did they block the exits?!' shocked Smog when he saw all the exits being blocked by 3E students.

As if Karasuma sense a doubtfulness in Smog, he started to stand up, "The minute you saw us, you should have held off attacking and gone back to tell your boss," said Karasuma.

"I'm surprised you can still talk. But all that's left is a bunch of kids. Once you're dead, they'll stop following orders and just run away!" said smog and he ready to attack Karasuma again with his gas.

Before he can do that, Karasuma kicked his face with inhuman speed and as if it was his last strength Karasuma fainted for a while.

"Karasuma-sensei!" shout the class, half of them come to their teacher and half of them roping Smog, so he can't move again when already regaining his consciousness.

"Karasuma-sensei! Are you okay?!" ask Nagisa worriedly.

Karasuma tried to get into his feet but failed, then Isogai help him to stand up.

"I'm okay, let's get going" replied Karasuma, his breathing a little bit hard. They continue their mission again now.

"You can't keep going like this, Karasuma-sensei," said Isogai.

"I'll be better in a half hour, just don't do anything crazy within that time," replied Karasuma.

"He's the crazy one. That much gas can freeze an elephant!" sweatdroped Sugaya.

"Karasuma sensei kind of a monster himself," said Okano, still unbelieve with what their teacher done earlier.

The mision team continue their journey, with Karasuma leading them. But now they must do it carefully, with the current their teacher conditions.

"Man, it's sure starting to feel like summer vacation, am I right?" said Koro-sensei suddemly with his sun printed face.

"What are you saying?!" shout the class angrily.

"Nagisa! Twirl him around till he's sick!" and Nagisa do as they said. It's become a total chaos especially if you have Akabane Karma in you peers.

Before Karma really make Koro-sensei goes to one of the male students pant, Nagisa pull away her hand from Karma grip.

"Koro-sensei, why does this feel like summer?" asked Nagisa.

"Teacher-student relationship is not a cozy one and summer vacation is like a foster student independence it's a place that beyond teacher's protection. If you apply the lessons you've learned in your usual gym classes, there will be few enemies for you to fear," said Koro-sensei as if he know what their worries just now.

"This is your assassination vacation and you can beat it," continue Koro-sensei.

His word really made the class relaxed for a bit and finally they can at ease after now. The mission continued again and this time they go with a new strength.

This summer vacation was one of many memories that they will never be forget in class 3E, because there's no other summer vacation that they go in the future will be more exciting and adventurous like this one.

Someone already waiting for them when they arrived at the fifth floor, it's a tall man with neck length hair.

"Oi, why's he just standing in the open like that?" said Sugaya.

"The vibes he give…" said Yada.

"Yeah, I can totally tell it. if it's kill or be killed, he'll kill," said Yoshida.

'His sheer strength is no doubt a top notch. Forget a surprise attack or strength in numbers. Dammit, I wish I had a gun with real bullets in my person. I never thought than gun will be needed in this island,' thought Karasuma while after he observe the situation.

Suddenly the man cracked the glass window with his bare hand.

"What a drag, hm, " he said, "If I can hear your footsteps, you're not though enough for me, hm."

"Supposedly some special-forces teacher was taking the lead too, hm," continue him, "I think Smog's gas must've gotten better of him, hm."

"Come out, hm" command him.

'He cracked the window with just his hand!' thought Kimura.

'B-but more than that… we're all too afraid to say it…, but.. well….' thought the class.

"You sure said a lot of "hm", uncle!" said Karma as if he knows what the class think.

'Thank God for Karma!'

"I heard it would make me sound like a samurai, hm," replied the man.

'So he's not a Japanese…' thought Nagisa.

"But it doesn't matter, if I can kill you all I will drop this "hm" term," said the man again while cracking his hand.

"So, your killing weapon is your hand?!" asked Koro-sensei.

"There's actually quite demand for this, hm. Everyone called me Grip, because the strength in my hand known to be feared," said the know they know as Grip, "I could snap their necks or crush their skull if I feel like it, hm."

"What a letdown, I come to here to searching for a fight. But it seems someone who's worthy to become my opponent is already taken down before the fight, hm." Continue Grip.

When Grip continue his talk, Karma turn around and come to grab the fake plant behind them. Nagisa eyes filled with worry when she see this.

Karma stopped when he's at right in front of Nagisa, "You don't have to worry about me, Nagisa-chan. You know I can do it," said Karma with a low voice so Grip can't hear them.

"I know… but it still dangerous, he's a pro killer," replied Nagisa with the same low voice.

Some of their classmate trying to hear their conversation, but some of them still focused on Grip.

Karma took off his necklace and give it to Nagisa's hand, "Just take it as my promise, that I will be okay, you gotta give it back to me when I'm done," said Karma with a cheesy grin.

Nagisa look at the cross pendant and ring that matching with her own, then she looked up to Karma something in his eyes that said to her that he will be okay, "Okay… be careful," said Nagisa.

"That's my girl," Karma whispered to Nagisa ear and give her a small peck on her right cheeks. Nagisa's cheeks went red at the action.

"For my recharge," said Karma and he walked over to grip.

'Please, please be okay Karma-kun,' said Nagisa while gripping at the red head pendant.

CRASH!

"Hey, uncle, hm," said Karma arrogantly, "You're pretty average for a pro, aren't you?"

"Breaking glass, busting skulls? I can do that, too. But if your opening move is to call in reinforcement, maybe you're too scared to take on a junior-high kid alone," continue him and make the others shocked.

"No, don't be reckless!" said Karasuma.

"Stop right there, Karasuma-sensei," said Koro-sensei before Karasuma can said anything, "His chin is down."

This make Nagisa and the others looked at Karma, "Nagisa-san, you're the one who's the most closer to him. You can tell the difference right?" asked Koro-sensei.

"Yes… there's been a change within Karma ever since he failed in midterm exam," replied Nagisa.

"Yes, usually he's always had his chin up and looking down at his opponent. But this one is different, his words maybe as rough as ever, but his eyes are looking straight ahead, alert and observing his foe head-on," explained Koro-sensei.

"Come on, uncle, let's get started, hm," said Karma.

"All right, hm. Let's see what you can do, hm." Said Grip and he took off his coat.

The fight between a pro killer and a junior-high school student. An adult and a boy, but this fight will always be remembered. This fight is the beginning of a new relationship for a certain red-head boy and blue-haired girl. The starting moment when they started to believe in each other again.
