The man gave the students a simple nod, an amiable smile plastered on his face as his dirty-blue eyes swept the classroom. Although he didn't carry a weapon, threatened them, or showed any hostility, the 3-E students couldn't help but feel like they would be swallowed whole, leaving only their bones to rot behind.

"Good evening," the male greeted with a slight smile, eyes glinting with minute boredom yet always polite and business-like. "You may call me Oshiro-sensei," he introduced, chalk in his gloved hand as he began to write his name on the blackboard.

Apart from the scratching of the chalk against the board's surface, there was no sound. The man gave off a different feeling from their other instructors. Koro-sensei was goofy yet skilled. Karasuma-sensei was demanding but caring. Bitch-sensei was— well, bitchy but kind. And Shimamori-sensei was cold but attentive.

Yet, the raven head in front of them only gave off a disturbing feeling of morbid courtesy. As if he wasn't looking at them but at corpses, he didn't care for them, he only saw them as inert beings, pebbles on the street. It wasn't the gaze the main building students used to look at them as if they were mere ants under their foot, it was another type of disdain— unlike the main building, this man couldn't be bothered to do so much as glance at them.

Oshiro set the chalk on the counter, his amiable surgical smile never leaving his lips as he turned to face the class. "Until the target's death—" his words sent shivers down the class' spine. Death, although they knew it was the inevitable result, to say the word so casually unnerved them. "I will act as your class' nurse," he said.

He waited a few seconds for the words to sink in, his black-rimmed glasses seemed to glint under the artificial lighting. "Do you have any questions?" the inquiry was more courteous than anything, Oshiro obviously didn't give a damn about their questions.

The one who raised his hand was a red-haired student who sat at the back of the class. With his foot on his desk, his mercury eyes challengingly stared at their new "nurse."

"Aren't you Bitch-sensei's colleague?" he asked, a sly smirk dancing on his lips as he raised a provocating eyebrow at the male. The question made the way the students looked at the underground surgeon change.

How to put it. It wasn't that they didn't trust Irina's abilities, skills, and knowledge, or her lethality as an assassin— well perhaps they didn't believe it as much as they should. But Irina dubbed Bitch-sensei by their class, was like an itchy kitty. Sharp claws but infinitely endearing after knowing her.

They couldn't help but think, was the man the same? A Tsundere? Someone whose cold heart once thawed burnt with a bright and warm flame?

They collectively narrowed their eyes on the hitman, trying to decipher hints of such a personality in the man's demeanor. Well, at first sight, there were none but maybe he hid his game well. 

Hmm, they really liked the hypothesis.

Oshiro seemed unbothered by the change in their gazes, he kept a clinical smile on his face and a dissecting glint in his eyes. "Bitch-sensei?" he echoed, and strangely enough, when the vulgar word slipped past his lips it lost all derogatory undertone. "Oh, did you perhaps mean Irina?" he rhetorically questioned, after all, she was the only female staff.

Fuwa was the one to speak up, perhaps she felt lingering embarrassment at the way the raven called her teacher, she couldn't help but explain how the nickname came to be. "Y-yes, but Bi— Irina-sensei doesn't mind the nickname!" under the raven's penetrating gaze, she didn't manage to call the blond by her nickname.

Oshiro merely hummed. "Is that so," he acknowledged, but no matter how they looked at him or measured his words, they didn't know if he was bothered or unconcerned. "To answer your question, boy, Irina and I do come from the same organism."

The hitman's eyes swept the room once more as if to silently ask them for another question before he beamed at them, sending another chill down their spine. "Then, if that is all, I will be on my way," he bade with not so much as a slight nod before he turned on his heels and went to explore the building that would make up his base for the following months.

His varnished shoes cleanly hit the ground, the sound oddly loud and well defined. This man was the real deal. No doubt about it that he would kill them in cold blood if given the opportunity.

Oshiro toured the school grounds with minute attention. His gloved fingers grazed the walls as if to test the surface, he came across Irina and gave her a simple nod as she walked toward the classroom. Irina was in charge of teaching them this morning, and at the moment only the two assassins were there.

Oshiro toured some more, taking note of potential places where he could pin some traps before going out. He left his suitcase in his dedicated labora— nurse room, and made his way outside for some fresh air. His shoes hit the dust and he inhaled the cold air. He felt his nose twitch.

Oshiro, perhaps due to his important manipulation of toxins, had an especially sharp nose. It wasn't to the point of being called a dog, there existed hitmen with more sensitive olfactive capability out there. His eyes snapped to look at the path that led down the slope. Someone was coming.

He saw the figure of a man appear in the distance, a very tall man. Most probably someone from the military he deduced from the male's gait and pace. The man stared at the ground as if to analyze the pebbles and only looked up once Oshiro could clearly make out his figure.

He lifted his gaze. Icy-blue met dirty-blue. Oshiro felt a shiver course through his whole being, images and names he didn't know streamed his mind. He didn't take a second to process the information, already dashing at the stranger and brandishing his paralytic poison coated scalpel at the man, ready to cut through his carotid.

Although Takashi was left slightly dazed when he met the hitman's gaze, he was a trained agent, and quickly reacted to the surprise attack. Barely dodging, he didn't have time to ask for an explanation before the shorter raven head stroke at him again.

It went on for a few more blows, the commotion quickly caught the students and Irina's attention, leaving the youngers to gawk at the scene while the blond internally freaked out. Shit, she couldn't have Kyoya killing their colleagues first thing in the morning!

Takashi dodged yet another blow, he didn't know what to do, should he retaliate? But the person in front of him obviously was Kyoya, how could he strike him? Wait, why was Kyoya even attacking him in the first place?

Kyoya's unreadable face contorted into a pained snarl the more he attacked. Each strike made his head throb, and each throb brought with it undesired images and voices. 

What kind of sorcery was this? 

Hypnotism?

He gritted his teeth, aiming for another of the taller's vitals. This time, Takashi went on the offensive, he disarmed Kyoya with ease— the surgeon's grip on the weapon was slightly loose, maybe from fatigue? And sent the scalpel flying more than ten meters away from them. He thought the assault would stop, but Kyoya wasn't the type to let go.

The moment he felt his weapon slip from his fingers, Kyoya let it go— with his poor grip on it and the strength difference, he would lose more energy trying to prevent the disarmament. Instead, he grabbed the man's extended arm and in a familiar judo move, sent him tumbling to the ground. He didn't leave him time to stand up, sitting on the male's chest and restraining his movements— though with how the other didn't struggle it wasn't hard, he pulled another poison coated scalpel from his cuff.

"You—" Mori-senpai, a voice corrected in his mind, making him wince. "What did you do to me?" he threateningly asked, scalpel dangerously close to the man's vitals.

Although from the classroom they couldn't make out their talk, they easily saw how the events went, and how Oshiro held a weapon to Shimamori's throat as if it was the most normal thing to do. Irina wanted to cry. She hoped Karasuma or Koro would get here quickly.

Takashi blinked, not quite understanding the question until he noticed the conflicted, scared, and confused look in Kyoya's eyes. 

Was it that Kyoya thought he wanted to harm him?

His eyes softened, sending the hitman above of him in strange disarray. He lifted his hand, and strangely enough, although it reeked of danger, Kyoya merely observed the limb with caution. Takashi brought it to the adult's head, slightly petting him. "It's okay."

Kyoya frowned, there was no mask on his face. No matter how much he wanted to pull his most well-crafted mask to cover his feelings, he couldn't help but slip out of it.

"You," Mori-senpai, the voice repeated. "Who are you?"

Takashi blinked, unlike with Mitsukuni who wanted confirmation, Kyoya wanted order in his head. Takashi didn't know if Kyoya was asking about now, or before.

Finally, after a beat of silence, the agent answered. "And you?"

Kyoya pursed his lips—

You may refer to me as Oshiro, I am a hitman sent by the government to take out the target. I will be standing in as a nurse, pleasure to make you acquaintance.—

Is what he should have said. Yet the moment he heard Takashi's words, like a dam breaking under the floods, words he couldn't control flowed out of his mouth, and with it images and clearer memories infected his mind until he couldn't make out the truth from the lie until the lies became the truth.

Until what he thought was a mere trick of hypnotism wasn't anymore.

There was a pregnant silence. Kyoya felt immense shame build up inside of him, yet he didn't show it. Storing his scalpel faster than ever before, he abruptly stood up, leaving space for Takashi to breathe. "My deepest apologize, Mori-senpai," the courteous words slipped as easily as he gave a deep bow to the man.

The entirety of 3-E and Irina who watched the scene from start to finish could only look with confusion. The hell was going on?

"I didn't recognize you," Kyoya explained, readjusting the rim of his glasses atop his nose as he gave the formerly older male a nod.

Takashi grunted, silently shaking his head to show it wasn't a big deal.

Kyoya released an unnoticeable sigh of relief. He noticed class 3-E and Irina staring from the corner of his eyes and plastered a beautifully well crafted plastic smile on his face. He gave the audience a smile that sent chills down their spines before turning to the impassive Takashi.

"Would you mind going out for a drink?" he proposed with a raised eyebrow. Although he came to terms with those 'memories', he wanted more information, and he had an inkling that speaking would help him revive them.

Takashi gave a nod of approval, and the two began to silently make their way down the 3-E slope. Takashi sent a message to Karasuma, his direct superior to tell him he would meet with the new hitman, while Kyoya contacted Irina and told her not to worry.

"Kyoya," Takashi called out, his voice low and unfeeling— though Kyoya was sure he deciphered hidden joy and delight in its undertone.

The raven-haired hitman hummed at his name. Lightly readjusting the position on his glasses, he glanced up at the taller male, slightly nodding his head. "Yes, Mori-senpai?" no matter how strange the name sounded as it rolled off his tongue, Kyoya couldn't help the surging familiarity in his heart. Calling the male anything else sounded uncomfortable and way too bizarre.

"It's good to have you back," the former host said, a slight smile on his face as he gazed down at the raven head with a caring look in his eyes.

Kyoya paused, he didn't notice his eyes softening, the kind edge of his smile, or the compassionate tone his voice adopted. "Yes, it is good to have you back too, Mori-senpai."

Takashi nodded, the slight smile never fading from his lips. "Mitsukuni will be happy too," he lightly added.

Mitsukuni, the name reverberated in Kyoya's brain, leaving the image of a blood upperclassman to appear in his mind. Honey-senpai, the same voice whispered. "Honey-senpai?"

Takashi gave him a sidelong glance before lightly humming. "Yes."

Before I knew it, this chapter reached its end and Mitsukuni didn't appear...

Oh well ¯\_(ツ)_/¯
