Day three: karma time

Outside of the building for 3-E Class a P.E. lesson, like the class the lesson wasn't about the normal things as they were holding the knives that could harm koro-sensei. Anyway with the students learning how to hold and swing the knives properly, there was one that was watching from afar.

Blue eyes were scanning each student taking in how stupid they looked while shouting out 'one, two, three, four' altogether the student that was missing thought it was pointless as they don't have the right build for the job... but what is he saying, he hates using knives when he has his claws.

A sigh left the boy as boredom over comes his mind, not liking to be bored he jumped out of the tree, where he was watching the class, as he started to make his way over to them. Wondering who this male is? well its no other than Killua, the ex assassin. As Killua was making his way over he failed to notice that karasuma-sensei was watching the young male and that killua had caught nagisa's attention since in the mornings killua normally isn't in school until later on, maybe second period if they were lucky.

Anyway, when killua got closer he could hear that koro-sensei was complaining that he felt left out and that the students like his P.E. lessons more than what they were doing. Personally, killua thinks that P.E. itself was a waste of time but he knows that no one would listen, apart from nagisa and the koro-sensei after all he doesn't talk to any of the other students so why would they listen to him if he doesn't listen to them?

"Yea, right. Your physical abilities are too far out there."

"Don't you remember what happened last time?"

Both Sugaya and Sugino said with slight frowns on their faces as they plus the whole class remembers, minus killua who wasnt there at the time, killua slightly sweat drops as he watches koro-sensei sulking. He soon blocks his hearing when the students started talking to karasuma-sensei about training how to kill koro-sensei when he was around. Anyway, thinking this was a great time to try and assassin him, killua slowly made his way over to the sulking octopus, with a smirk killua puts his plan into action as he started to use the assassin technique he learnt from his family.

With one of the techniques Killua has learnt is one that is called 'Rhythm Echo' which allows Killua to have afterimages of himself to confuse others as the afterimages and killua look the same as well as being silent. Anyway koro-sensei looked up from making some type of a sandcastle that started to form, Killua ignores that the others could be watching what happens, the yellow octopus didn't have time to think what had happened when one of his tentacles had been cut off and that the afterimages of Killua had disappeared.

Before Killua could get him again, koro-sensei had used his speed of mach-20 to 'defeat' Killua, a shout was heard making the rest of E class look behind karasuma-sensei to see Killua with his hair tied back but also with his claws painted.

"What the hell Koro-sensei!?"

"Hehe, Killua you should really keep your hair like that~"

Koro-sensei giggles at the blushing Killua as the young male started shouting at koro-sensei before shaking his head to get the headbands out of his snowy hair, karasuma-sensei shakes his head at the immature teacher before turning his attention to the rest of the class infront of him.

"Isogai-kun, Maehara-kun, step forward"

Karasuma-sensei sharply said making the two males step forward to their teacher as they wait for the command from the P.E teacher.

"Try to strike me with those knives."

"A-are you sure?"

"As a team?"

Isogai and Mashara asked him as they were shocked and slightly off guard when karasuma-sensei ordered them to do since they didn't want to harm their teacher but karasuma-sensei was able to calm their nerves down by saying that the knives were harmless to humans. Though seeing that they weren't going to strike him without hesitation so instead of pushing the matter by keep saying they won't harm him nor other humans he decided to strike a deal by saying that if they were able to touch them even lightly, they'll be able to go home for the day.

Killua sighed as he gave up by arguing with his unusual teacher as he was sitting down a few feet away from the group to watch what would happen. It wasn't long when is Isogai lunged at him but karasuma-sensei did a side dodge making Isogai tilt forward, it wasn't long when Mashara decided to have his go but instead of going forward like his friend, karasuma-sensei had dodged but also gripping on the boys wrist and shoulder as the teacher pushed him away.

Mashara And Isogai kept on attacking karasuma-sensei only to have him dodge and counterattack slightly to the attacks the two teenagers did while talking how little training even karasuma-sensei can handle the knives of two amateurs. The reaction the teacher got from Mashara and Isogai were sharp grunts as they look away ever so slightly in embarrassment while the class were shocked what their own teacher had said. Not liking to be looked down on the two teenagers charged at karasuma-sensei only to be flipped onto their backs harshly making them groan and grunt in pain.

"If you can't even hit me, you haven't got a snowball's chance in hell against our Mach-20 teacher."

Even though it sound harshly and discouraging the students, even Killua felt slightly discouraged by the harsh words karasuma-sensei had said they all know that it was the hard fact of the truth that if they can't hit a normal human then how in the hell would they be able to hit a creature like their other sensei?

"See? While we were sparring, he built Osaka castle in the sandbox, changed clothes, and brewed up some tea... also don't forget Killua had tried to assassin him!"

Killua blushed slightly with a 'tch' at the remainder that he failed his first assassin attempt if you don't pick the first one, anyway as karasuma-sensei was helping Mashara and Isogai back up while saying that if the whole class was capable of hitting him, then the chances of being successful would increase dramatically. Killua stands up and moves over to the others as he was now standing behind Nagisa, with his arms crossed, when karasuma-sensei turned around to face everyone, minus koro-sensei.

"During P.E., I'll be teaching you stabbing, shooting and the other basic of assassination."

Killua rolls his eyes as he wraps a loose arm around Nagisa's shoulders making the smaller male go tense before relaxing when he realised that it was just Killua, as the class was dismissed Killua had stayed with Nagisa slightly surprising the others since he normally leaves though what shocked them more how close he was to Nagisa.

Anyway, as the class relaxes and started to chat between each other they didn't realise that there was someone else on the school grounds that has fiery red hair and amber eyes that was looking down on them... all but one as Killua felt someone watching them Killua slowly lets out his bloodlust to scare off the stranger that he hasn't seen yet.

As everyone started to leave they soon realised there was a teenage boy watching them with curiosity before his eyes landed on Nagisa and killua who were talking to Sugino as they were chatting about the quiz they have next period. Looking up Nagisa spotted the red head as he was slightly shocked though it made Killua feel annoyed that this male was stopping them from get changed and to get to the next period.

"Hey, Nagisa-kun. It's been a while"

"Karma-kun... you're back?"

Killua's eyes narrowed as he watches this 'karma' carefully as karma walks down the small steps towards as he was making his way over to koro-sensei, something about karma just doesn't settle well with Killua though he knew it was unfair to judge so quick but Killua didn't care, just how his aura and body language he dislikes karma.

When karma had stopped talking and walking he was infront of koro-sensei with his small strawberry milkshake Carton as koro-sensei happily lifts one of his tentacles as he started to talk to the new student. Killua frowns slightly as he noticed that karma wasn't reacting like someone would when they first see a giant, yellow octopus standing AND teaching a class of young students. Hey, Killua has no room to talk, after all he didn't react like normal people but he had a reason not too.

Something must of happened as koro-sensei's 'hand' exploded into yellow goo before karma strikes with a hidden knife up his sleeve, koro-sensei had managed to dodge the next attack as he started to sweat, karma started to explain how his 'hand' exploded and started saying to the teacher that how he was scared of his own pupil while everyone was in a state of shock or in surprise anyway it wasn't long when Nagisa started to explain why karma was within the class and how he might just top the class, seeing that Killua was going to have some competition he decided to make a plan how he could show karma that he was the one that was the 'boss' or the top of the class.

It wasn't long when karma started to walk away from the scared koro-sensei and the class, a strong bloodlust started to wrap around karma which had gotten Killua attention, maybe, just maybe, Killua could get friends in this class if he stopped being so judgemental and pushing everyone away if they have hidden bloodlust.

The second attempt karma did also got koro-sensei within the sixth period when the class was doing a quiz, how karma was able to get koro-sensei the second time was to put some BB bullets on the floor before tormenting the octopus by using his Italian ice cream to come closer to the BB bullets and killua has to say karma does have a good idea.

Later on Killua decided to walk home with Nagisa, a yawn left Killua as he watches Nagisa saying bye to Sugino though something had caught his attention as two males from the main site of the school started to bad mouth Nagisa.

"He must be right at home down in E class"

"What a lamer. He'll never make it out of there unless he shapes up"

Killua turned around as he sent them a hard glare, threatening them to carry on as Nagisa started to listen in and making him feel down about himself. Not liking this depressed Nagisa, Killua started making his way over to them, to put them in their right place.

"Plus, now that Akabane's back from suspension, he's in E class too!"

"That's the pits! I would seriously rather die than wind up there."

That was the last strew for Killua and it didn't look like he was the only one as karma had picked up a glass bottom before hitting it against the pillar behind the males while Killua managed to knock down one out of the two males as his claws were out as the long clawers were close to the males face

"Really? You'd rather die?"

"How about right now, then?"

Killua started before karma finished the threat as they moved closer to injury the males, Killua soon lets the male he had pinned on the ground go as they raced off in the fear of being harmed by the two males.

The two E class students walked back over to Nagisa as karma and Nagisa started talking while Killua was watching everyone going passed while listening in to the conversation though he pulled Nagisa back as a train went past though when karma started to talk how he was able to kill an actual teacher, an insane look appeared within the red heads eyes which started to make Killua slightly uncomfortable and he could feel that Nagisa was also uncomfortable but he pushed that away as the three males said good bye to each other.

The next day karma had been trying to assassin koro-sensei only for the attempts to be a fail but he kept on trying within the different periods anyway Killua has been keeping an eye on karma and sometimes if the ex assassin was lucky enough the two would chat with each other and that's one of times now.

"Is mr snowball jealous that he's not the top of the class?"

"Whatever, light tower but I'm going to tell you that you won't be able to kill the octopus without the help of others"

That was the last thing the two said to each other before leaving as they went their separate way until after school as Nagisa, Killua and karma was on top of a cliff near the school anyway Killua was leaning against the tree while he listens to karma complaining how his attempts weren't not getting anywhere.

"Karma-kun"

The boys turned around to see koro-sensei had arrived behind them, koro-sensei started making his way over to the three, Killua walks over to Nagisa and karma as he watches the octopus come closer before stopping a few meters away from them

"I've certainly taken good care of you today, haven't I?"

"You can still try to kill me, you know"

"I'll polish you up even shinier"

Koro-sensei cheekily said as his face was green and yellow stripes showing that he was cocky at the fact that he doesn't believe that they'll be able to kill him. Karma huffs slightly as he stands up from sitting down on a tree that was hanging over the edge of the tree.

"Just to make sure... you are a teacher, right? "

Nagisa and killua looks at karma as they were trying to think why karma would say that, the two males turned slightly to watch the red head. As koro-sensei answered the male.

"Right."

"And you said you would risk your life to protect one of your students?"

Karma asked the teacher once more as he watches him quietly.

"Of course, I'm a teacher, after all"

"Okay, good. Then I can kill you"

"For sure"

They watch as karma falls back over the cliff with a gun raised at the sky while he falls closer to the ground, Killua snapped out of the shock when Nagisa shocked for karma as the blue hiared male tried to get to karma only to be pulled back by Killua as the snowy haired male dived off the cliff after karma hoping that he'll be able to catch karma.

It wasn't long when killua was able to catch karma when he was deep within his thoughts, seeing that the ground was coming closer towards them Killua flips the two so Killua was at the bottom to protect the taller male. However when the ground came closed the pair was caught by yellow tentacles that had made a sticky net to keep them safe.

"That was close..."

Killua sighed in relief as he relaxed within the net before letting go of karma's waist, karma was still shock that one, Killua risked his life to save his and secondly that koro-sensei had slipped between his fingers once again to save him and killua.

"Karma-kun splendid job on the premeditated assassination starring yourself. If I'd saved you and killua at Mach speed, your body's wouldn't have been able to take it and if I'd moved slowly, I'd have been hit. So I thought I'd try a stickier approach"

Killua scoffed slightly before looking at koro-sensei.

"No shit Sherlock"

The ex assassin snapped at koro-sensei as he tried to move his body from the sticky tentacles of koro-sensei's

"Damn! What can't these tentacles do?!"

"You can't shoot me now!"

Karma simply said as he struggles to get loose only to stop when killua headbutts karma harshly but also when Koro-sensei started laughing.

"Stop moving light tower!"

"Shut up snowball!"

The two males were starting to have an argument with each other but stopped when koro-sensei started to talk.

"Oh, and for the record: letting you die is not an option for me. Feel free to take a leap of faith any time you like and you killua-Kun"

A small smile made it on killua's and karma's lips as the sun started to set. It wasn't long when koro-sensei tales Killua and karma back on the cliff where Nagisa was waiting for them, Nagisa rushes over to see if the two were okay and unharmed, which they were.

"Well, I'm going"

Killua said as he started walking back home as he waves bye to his teacher and his classmates as he was wondering what the next day holds for them.
