The bell rang in the single classroom of 3-E as the students groaned when having to grab their bags from their lockers outside the class to get on their sports attire. The next period was physical education and today was most likely testing their combat skills whether it be with knives, fire arms or nothing but their fists; like they would need that for a biological alien like their own teacher, right?

Sugino walked down the steps to the grass beside his close friend Nagisa. The blue-haired boy sighed as he held his small notepad in his two hands in front of him, wearing his sports clothing with a hidden anti-Koro-sensei knife in his waistband.

Sugino looked over, deciding to break the silence while more and more students arrived onto the grass field, "So, have you got anything new in that notepad?"

Most of the students were grateful that Nagisa had taken it upon himself to list all of their teachers known weaknesses or other weird facts about him that they could use against him.

Nagisa took his gaze off of a lone cloud in the bright sky and looked up at Sugino, a sweet yet nervous smile on his face, "Uh not really, but... I wonder how Koro-Sensei would do with water? It's a bit odd but-"

"No, that makes sense, I mean we haven't seen him anywhere near water- good thinking Nagisa."

Nagisa glanced at Sugino momentarily, a pink tint on his cheeks from the unexpected praise, "Th-thanks Sugino."

Both boys stood in the sun as the whole class finally stood together on the grass, girls like Yada and Kanzaki crouching to rest for a little before Karasuma arrived with his expressionless face and piercing eyes. Everyone straightened up and watched the man while Koro-Sensei stood at the top of the stairs to observe, "You can leave, I'll be teaching them now." Karasuma spoke out loud, his deep voice startling Koro-Sensei before he giggled manically and left without a trace.

Karasuma was silent, confusing the student's for a little while.

--

"Naw why did you send him away! I thought we were tryna kill him, not practise with you!"

(Y/N) bellowed out loud, waving her knife in the air with a pout on her face. Karasuma sighed but didn't think of it for too long because (Y/N) was actually a pretty valuable student in the ex-military officer's opinion.

"We can't let him seeing our fighting techniques and strategies so I take physical education classes alone when I can."

"Hmmm~ That's nice, fulfilling your long lost dream of teaching student how to kill their teacher, so dreamy!" The (H/C)-haired teen shouted out with glee, a malicious gleam in her eyes, "Nagisa! Fight me!"

Nagisa yelped in surprise and side stepped when only just spotting the girls foot just inches from his face, he fell back with an 'oomph' and looked up at her frightened, "Oh! Sorry Nagi-chan, I guess it's uh... Unexpect- no ex-"

Tomohito Sugino looked around awkwardly before taking a timid step towards the dangerous teen as she stared down at Nagisa like he was her meal, "I think you mean expect the unexpecte- Ah!"

The baseball player froze and scrunched his eyes shut when a knife lightly and as quick as lightning, grazed his neck. He slowly opened his eyes to look down at the knife, following the hand, arm and shoulder up to the face of (Y/N), her tongue out in concentration as she held her smile in- making her look all the more scarier as Sugino's brain signals immediately told him to run.

"Like this, Sugino-kun?"

--

"Uh, Karasuma?" The man shook his head and glanced at the female class representative, Megu Kataoka, "Are you okay?"

"Uh, Yeah, I'm fine- now today we'll begin with two on one knife combat."

The students looked at the man questioningly, thinking to themselves about when they would get in a situation of fighting two people at once, Karasuma noticed and sighed, "You students aren't the only ones that want that ¥10 billion reward, you have to be prepared for anything."

The students sighed in sync and began pairing up, a couple students like Rio, Nagisa, and Maehara feeling a bit discontent with today's activity. Sugino stayed close to Nagisa as Kayano approached the two, "Hey guys, mind if I join you two?" The boys nodded, "Sure," Nagisa answered which emitted a pink hue on the green-haired girl's face.

Nakamura, Maehara and Isogai paired up in a trio without saying anything while all thinking the same thing.

--

"Two on one combat?! That's sounds so~ cool! I don't even know who to go with!" (Y/N) screamed excitedly, her eyes lit up like a child on a sugar rush. Nakamura smirked at the girl and once the blonde was in the girl's line of vision she heard a yelp, "Rio-chan! Be with me!"

Nakamura smiled and nodded, patting the girl's head, "Sure thing (Y/N)-chan."

She smiled and looked around, watching more student's already getting into groups of three, "Urgh~ I want to be with everyone though! Ka-ra-su-ma~!" She bellowed with a jump in her stance when yelling each syllable, the teacher turned with a roll of his eyes when hearing that voice, "Me and Rio-chan don't have enough so we'll take turns with everyone!"

(Y/N) laughed and thought about bringing her classmates to the ground below her with a manic smile that made Rio chuckle knowingly but stopped when she heard her classmates grunting as they fought while Karasuma-sensei approached the girls, getting into a fighting stance that intrigued half of the class's interest.

"Wha- we have to fight you! Oh, is it my birthday?!" (Y/N) yelled, bloodlust written all over her as her aura turned dark, bringing out a knife as she flung it around almost like a professional.

--

"To be honest, I'm not really in the mood.." Nakamura sighed as she picked on her nails in front of her. Maehara sighed while Isogai nodded as he also agreed, "It isn't the same.." Maehara finished as he stretched, placing his hands behind his neck.

Karasuma saw the three slacking off and slowly got closer to them while observing the student's like Nagisa as he practically slithered onto his blue-eyed friend, successfully holding his knife to Sugino's throat while Kayano watched with shock and admiration.

"Stop being lazy and do the exercise, alright?" Nakmara looked away stubbornly and Maehara cringed lightly when thinking about who would be the solo fighter between the three, the other two being the attackers, Isogai, not wanting to cause any trouble only breathed out and got into a fighting stance.

Maehara glanced at him surprised as Nakamura looked from Karasuma to Isogai- thoughts of her best friend filling her mind, "Uh, don't hurt me please?" The ikemen spoke shakily.

--

"Kayano-chan! It's my turn now~" The green-haired girl jumped at the voice, "Are you ready~?" The whisper from behind Kaede made her jump and scream at the same time as she fell back, watching the girl with the beady (E/C)-coloured eyes stare down at her.

Nagisa and Sugino watched with chills running down their backs, the knife in (Y/N)'s hand made them nervous while Kayano scrambled to her feet to get closer to Nagisa where she felt slightly more safer while (Y/N) was in her zone; not caring about the consequences.

It was times like these when the student's of class 3-E would feel extra nervous about physical education with Karasuma. There was a certain point where (Y/N) would have too much fun and it was like something was blocking her from thinking properly.
She only thought about dominating the other students as she stared at each and every one like a meal while she was on a empty stomach in cloud nine.

This was the moment that became dangerous for her classmates, no one knew if (Y/N) actually knew what she was doing or if she felt any remorse for her actions either. Either way she never apologised when she came back down to Earth.

"Whose up first~" The teen dragged her words, slowly approaching the three teen assassins, Nagisa gulped and held his arms out in surrender as to show that he wouldn't fight with the girl before him. She had somehow managed to escaped Karasuma as the man practiced with Nakamura.

"He-hey (Y/N), I th-think the bells gonna go- so u-uh let's go get changed fo-for class, okay..?"

--

Nagisa walked slowly, puffing lightly when he walked up the stairs to go the changing rooms before Nakamura ran right past him and entered in a flash. Kayano gulped but spoke of nothing and Sugino breathed out to relax his thumping heart from that activity with Nagisa and Kayano.

Nagisa felt the notepad in his pocket but his mind was on that day when you had escaped from Karasuma and wanted to practice with the three in a one on three match. He remembered trying to knock you out of your concentration zone where it took a long while to snap you out of your bloodlust, Kayano felt lucky that you were on their side and not someone else trying to get the bounty for their teacher.

Nagisa recalled saying something about  the bell that was going to ring but you didn't move, your eyes only followed his arms that were getting closer to you, to your knife.

You were breathing loudly, almost in an animalistic way before you reached forward to grab the boys arm and flipped him, only Nagisa saw it coming and palmed your arm away from the side. He grabbed your other arm, squeezing as to make you let go of your knife- as you did from the shock settling in.

You had made an awfully feminine yelp which made Nagisa think he was doing alright but before he knew what was going on, he already had you on your stomach in the dirt, your arm that had been holding the knife was twisted behind your back and Nagisa was straddling you from behind.

Nagisa recalled breathing out in relief when he thought he had knocked you out of your zone only to hear a yell from Sugino calling his name before a growl was heard.
Nagisa gasped when such strength he didn't know you attained, caused you to thrust your arm out of his grip and swipe it, hitting him across the head as you turned your body. Flipping over, you huffed as you sat on your bottom, Nagisa cradling his head as he smiled nervously and in obvious pain.

That day you made Nagisa gobsmacked when you muttered out an angry apology and got up, stomping away to the changing rooms where he currently was, feeling a cold draft on his legs.

The androgynous male blushed a deep red and looked down only to yelp and run to his bag, shuffling through it's contents as he yelled, "Nakamura-san! Please give me back my pants!"

Nakamura chuckled loudly, her phone out while she rocked his pants, loving the way her skirt made him look adorable, "(Y/N)'s gonna love this."
