Lazily getting out of his limousine, the chauffeur opening the backdoor for him and handing him his schoolbag, Byakuran brushed his white bangs back, revealing his smug pair of violet eyes to the awed and curious Kunugigaoka students.

A smirk danced on his lips, a satisfied chuckle slipping past them as he slung the bag over his shoulder before receiving a freshly brewed thermos of hot cocoa and sprinkled marshmallows in his hands. He brought the hot beverage to his lips, satisfyingly humming as the sugary drink burnt at his throat before going inside the school grounds, merely dismissing the limousine and chauffeur with a wave of his hand.

A delegate from the Japanese Varia Cloud division, the chauffeur, deeply bowed as he bade a polite goodbye, waiting for the teen to disappear from his sight before going back to his vehicle and driving away.

The white head basked in the attention, and the whispers addressed to his person. Wealth was power.

Byakuran was insanely wealthy.

Monday passed, Tuesday came in strides, and after bidding his brother a good day, Koro worked on some leftover paperwork. He had decided not to drive to Kunugigaoka with the younger boy as their schedule wouldn't always align. He also did not wish for Byakuran's reputation to suffer from his early affiliation to 3-E.

Although Koro loved the class, it did not change how biased the main building was against anyone affiliated with them. Until Byakuran's footing in 3-A and Kunugigaoka was well established, he'd refrain from publicly showing their affiliation.

Tuesday went by. By then, Koro received reports on 3-E's latest doings, a compilation from the government that his underlings had checked before adding some details. Namely more detailed information on their latest addition, the hitwoman, professional honeypot: Irina Jelavich.

As he remembered, her assassination attempt on Monday failed, and she was now posing as the students' foreign languages teacher. Her nickname was also Bitch-sensei, as it had been previously.

Koro brought his espresso cup to his lips, appreciating the mild effect of caffeine on his system before he set the empty cup down in the sink and walked to the bathroom. He pulled his pair of green contact lenses, efficiently placing them over his purple irises. He blinked, waiting for his eyes to get accustomed to the accessory, and picked the pair of black-rimmed glasses by his side, gently perching it atop of his nose.

His fingers combed through his dyed blond hair, brushing them and taming them some more before he turned away from the mirror and walked out of the bathroom. He picked his brown leather briefcase with the relevant teaching material neatly stored in it, double-checked for his weapons, and made his way out of the condo.

It was half-past ten already, but Koro was in no hurry. His first class would only be in the early afternoon, right after the lunch break.

Though, as a Varia member, even if he didn't go as one of the executives just yet, he ought to make a beautiful entrance. His lips stretched into an excited smirk, deviously curling at the edges as he envisioned his plan for the last time.

The lift brought him to the underground parking lot. He took his keys out, turning on the noticeable pearl blue car in front of him. The color fitted his current aesthetic, as did the expensive yet accessible model in front of him.

Koro hummed, eager.

Truthfully, Karma hated to admit it, but 3-E's classes were interesting.

Not that Aguri-sensei's class were boring or anything— he wouldn't have known. But Karma hadn't expected much when he first got notified of his transfer after the beginning of the term. He thought it would be a chore. Simply hiking up to the building was annoying so imagine if he also needed to pay attention to classes!

Fortunately for him, and unfortunately for the Human population, his homeroom teacher Koro-sensei entered the picture. Now everything was way more exciting and entertaining.

He was almost tempted to stop skipping classes, but habits died hard. What could he do?

Anyway, the week had begun on a great note. Bitch-sensei, a new addition to their small 3-E committee and a great entertainment source, was the first good news. Although she wasn't so likable when she came in, acting all high and mighty, she was now bearable and almost endearing.

So imagine the anticipation when they learned that not one but two assassins were actually going to join their class this week! Iri—Bitch-sensei was the first one, a professional honeypot with an attitude and skimpy clothing. Who would be the second one?

Male, female? Honeypot, snipper, mercenary— it didn't really matter. Karma felt curious either way.

He brushed his sweaty red bangs out of his face, taking a breather from his P.E. class as he picked his water bottle. They were on a small break, with Karasuma-sensei taking his time to point out some recurrent mistakes in their form and Koro-sensei playing in the sandbox on the side— as usual.

Bitch-sensei was not sunbathing, April weather not being the hottest, and stood by the side of the field, observing them and minutely flicking her eyes from student to student as if to assess them. Although not the most proficient in hand-to-hand combat, she was a pro. She had a vision for this type of thing. It came with the job. Or so Karma supposed.

Drinking in their P.E. teacher's words with interest, Karma set his water bottle down after capping it. His mercury-colored eyes swept over the training field, a creation of their homeroom teacher before he looked back at the raven-haired governmental official.

He didn't know when, but Koro-sensei stood next to Karasuma-sensei, a comb and towel in hand as he dried the male off his sweat at Mach 20 speed. In return, Karasuma-sensei kept on aiming at the yellow octopus with one of their special knives.

Karasuma heaved a sigh as he put his knife away, Koro-sensei's signature laughter and stripped face answering the motion with ease. "Okay, break's over," the raven-haired teacher announced as he clapped his hands. "Let's get back to training—"

A violent explosion cut off the military agent, making the ground shake and the adult's eyes widen. Bitch-sensei abruptly stood up as a cloud of smoke took over the entirety of the training ground. An unsettling silence fell over them, thoughts racing a mile an hour as they realized that this surely was the act of the second hitman or woman.

A second of pure silence and a myriad of detonations followed, draping the entirety of the hill in a thick veil of black smoke. There was no way for the students' untrained eyes to see what was happening. With how dense the smoke was, Karma doubted that their teacher could see or smell more than the smoke bombs or explosives' burnt smell.

Bullets whistled, Karma thought he saw a patch of yellow move around. Still, he wasn't sure, the tiny particles clawing at his eyes and preventing him from keeping them open.

He swore he saw a flash of deep purple dancing in the darkness of the fag, seemingly illuminating a path for a split second. With the violet color and the loud thumps it brought, there was a blurry mass of yellow. Probably the hitman fighting against their homeroom—

They weren't honeypots.

With each swish and dull sound, the smoke around grew thinner, probably dissipating with time or because of the velocity of the two's movements. It became easier for Karma to see what was going on. He squinted, rubbing his eyes with his wrist to make his vision clearer.

The smoke progressively vanished, and there, in front of their eyes, was a man, a tall man, as tall as Karasuma-sensei, give or take. He stood, breathing regular if not slightly ragged and a broad smile on his face. His hair, a light blond color appeared almost grey from the layer of smoke around him, and his eyes seemed to shine with minute purple reflects. Like the violet blurs, he thought he saw through the thick veil of fog before. Karma blinked. The man's eyes were, in fact, a deep green color. They shone with amazement maybe as they gazed straight into their homeroom's beady eyes.

In the man—hitman's hand was an anti-gun, neatly aimed at their teacher's tie. Precisely, the crescent sewed on it. His grip on the gun was comfortable, not relaxed but not stiff either. It was apparent the man often held such devices.

No one moved as they observed the gun's muzzle with batted breath.

The blond's lips stretched into a broad grin. A perfect business smile with evident childish edges as the hitman retrieved his gun from its position. With a practiced twirl around his fingers, he placed the firearm in its holster.

The man moved, unbothered by the fact that he hadn't managed to kill their teacher— as if that wasn't his goal. He gave an exaggerated curtsy, lowering his form just enough to need to tilt his head to look up to their homeroom teacher, who sat on the ground.

"A pleasure, Koro-sensei," he greeted, voice crisp as his green eyes crinkled. He stood straighter and extended his hand to the yellow octopus.

For a flicker, Karma wondered if the hitman had attached some anti-blades to his palm as he did when he first came back to class. The answer was no. Koro-sensei's tentacle did not melt upon contact as he seemingly hoisted himself up with the blond's help.

"Let us work well together?" the blond added as his green eyes twinkled under the sun. His head tilted slightly backward as he looked up at Koro-sensei's much taller figure.

Koro-sensei's recognizable laughter escaped his mouth, his large grin overtaking his face as green horizontal stripes appeared all over his yellow head. "Nyurufufu~ No more bullets?" their teacher taunted with a lilt.

It was only then that Karma and probably the rest of the class understood why Koro-sensei hadn't moved when the gun was so straightly aimed at his tie.

The blond merely smiled at the taunt, unbothered.

"What a shame!" Koro-sensei added, his voice almost a drawl as his laughter overtook it.

"Fufufu, yes," the unnamed hitman agreed with a tilt of his head as he sheepishly rubbed at the nape of his neck. His cheeks coated themself in a light pink tint as if embarrassed and his broad grin dropped into a wry smile. "I like to take my time with my preys," he whispered, his green eyes suddenly sharper, glinting with a dangerous and murderous edge as his lips twisted into a ravenous smirk. A wave of killing intent emanated from the foreigner, the pressure lasting a mere second before it vanished.

There was a clear contrast between the blond's exhibited character— quirky and easily embarrassed, and the persona he seemed to adopt as an assassin— bloodthirsty and manipulative.

Karma did not think that they all heard the male's whispered words, but they certainly felt the wave of killing intent he released during this split second.

He wondered if the hitman would bother with playing innocent in front of them or if, like Bitch-sensei, he'd dismiss them the moment no other staff was around. They were 3-E, sadly long used to this type of treatment. What's more, the hitman's career plan wasn't to teach them but to eliminate his target— namely Koro-sensei.

Karma's mercury-colored eyes met the pair of green orbs that efficiently swept over his class. Both colors clashed for an instant. The blond was not wasting time resting on each figure and intently analyzing them. From the corner of his eyes, he saw Bitch-sensei's blue eyes narrow at the hitman, obviously alerted by his behavior. Although she couldn't have heard his whisper, her instincts probably screamed at her to be careful.

Karasuma-sensei walked up to the duo, a frown etched on his face, as usual. Otherwise, wearing a poker face, he placed himself in between their homeroom and probably the new teacher before greeting the blond. Karma noticed how polite Karasuma-sensei was, much more courteous than with Bitch-sensei. Then again, it could be because of Bitch-sensei's first impression. Still, the blond man's entrance wasn't much better in terms of politeness or whatever.

It rubbed Karma the wrong way. He tucked the information in the back of his mind for later use as his eyes followed the two adults walk back to their main building and probably the teacher lounge. Koro-sensei was the one to dismiss their class, announcing early recess and lunch break for them.

Karma's mercury eyes narrowed, and his flattened lips twitched upward. He turned on his heels, noticing Nagisa's shaken figure on his way. The blue's eyes trailed behind their new teacher, unblinkingly. It was weird and unsettling. It made the redhead frown before hitting the back of Nagisa's head and snapping him out of his stupor.

"You okay there, Nagisa?" he challenged with a smirk, watching as his friend tottered from the impact before wincing and grumbling.

"Ah, yeah, thanks, Karma," Nagisa whispered, looking up at the other male with a strained smile.

Karma frowned. "What? 'There a problem?" he quipped, leaning his weight on his left foot as he tucked his hands in his P.E. uniform's pockets.

"Nuhu, nothing, let's go change!" Nagisa denied, flashing an obviously fake smile at the other teen before leading the way back to their class to change out of their P.E. uniform.

The redhead did not believe Nagisa, obviously. Yet, he did not ask again, deciding against snooping into the bluehead's business if he didn't want to share. Lightly humming to himself, his eyes half close, he trailed behind Nagisa's more petite figure and into the prefabricated.

Nagisa walked in silence, images of the blond man replaying in his mind like a broken cassette. There was something wrong with him. He didn't know what, and that made him scared. He felt like the blond was not supposed to be blond. His deep green eyes were not the correct shade either.

Some voice in his mind was screaming at him that he already knew the man, somehow, but Nagisa couldn't seem to remember how and when he met him. Everything was blurry and his mind a mess.

He wondered if he inhaled too much smoke before. Maybe that made him dizzy. That's why his mind was in shambles.

This scene is the one from CLOUDY's prologue! (I'm still undecided on whether Nagisa will remember meeting Koro, or if he'll remember the who Assassination Classroom timeline)
