The morning sunlight filtered gently through the curtains of their new mountainside house.
Akira stood in the kitchen, humming quietly to himself as he finished plating breakfast.
It wasn't anything fancy—just egg salad sandwiches with extra mayonnaise the way Erika liked, warm Darjeeling tea, and a small bowl of chocolate ice cream on the side.
The combination was weird, but these were the things she enjoyed most.
After what happened last night, he wanted her to feel comfortable.
He carefully carried the plates to the dining table just as soft footsteps came down the stairs.
Erika appeared, fully prepared for whatever the day would bring, her hair perfectly done with her signature red ribbons.
The moment their eyes met, both of them froze.
"…Good morning," Akira said a little stiffly.
"…Good morning," Erika replied, equally awkward.
She avoided looking directly at him as she sat down, trying her best not to think about what had happened last night.
She reached for her teacup and took a slow sip.
Akira sat across from her, watching quietly for a moment before casually opening his mouth.
"So… are we doing the handcuff thing tonight?"
"PFFFFFT—!!"
Erika instantly spat her tea across the table.
She started coughing violently, eyes watering.
Akira jumped up in panic.
"Erika?! What happened?! Are you okay?!"
He rushed around the table and patted her back.
And while she was still coughing—
Selena's cheerful voice echoed in both their heads.
"Oh? You two are already talking about it? Perfect timing. I finalized several restraint options last night. Leather, reinforced fabric, magic-nullifying alloy… I even made a cute pink pair~"
Erika finally stopped coughing.
Her face turned bright red as she slammed both hands onto the table.
"I JUST SAT DOWN! Who starts a conversation like that first thing in the morning?!"
Akira tilted his head in genuine confusion.
"But this is a really important situation, you know? We're going to school today. I couldn't really sleep, so I made a lot of things to help you."
Erika sighed deeply and rubbed her temple.
"…What is it?"
Akira's eyes lit up instantly.
He hurried to the kitchen counter and brought back a tray filled with several large bottles of deep red liquid, a few snacks, and a thick notebook.
"Tada! This is my 'Erika Vampire Instinct Stabilization Plan'!"
Erika stared at the items in shock.
"…What is all this? Are those blood packs?"
Akira quickly shook his head.
"No, those are pomegranate and beetroot juice."
Erika blinked.
"…Why?"
Akira proudly opened the notebook and began explaining.
"The red liquid isn't blood—it's a special pomegranate and beetroot juice blend. Both are considered miracle drinks for anemia. They're rich in natural iron and folate. I also added Vitamin C to improve absorption and some medical hematinic syrups."
He pointed at the bottles enthusiastically.
"These are meant to help maintain stability until we return home. If you drink them regularly and follow the plan, your bloodlust shouldn't trigger as easily. It won't completely replace blood, but it should reduce the chances of sudden cravings."
Erika picked up one of the bottles and examined it carefully.
"…I see. That's actually really thoughtful. I really don't want to attack anyone…"
Selena immediately cut in with a teasing tone.
"You won't attack anyone else. Only my brother. Because you like his blood that much~"
Akira nodded seriously.
"Yeah. If you ever feel like attacking someone, I volunteer as tribute."
Erika's face somehow became even redder.
"Stop talking! Why are you two always like this?!"
Just then—
Ding-dong.
The doorbell echoed clearly through the house.
Both Akira and Erika turned toward the front door at the same time.
Erika asked, still slightly red-faced,
"Who is it? We just moved in yesterday."
Akira waved casually.
"Oh, don't worry. I got it."
He walked over and opened the door.
Standing there with a bright yellow face and a mischievous smile was Koro-sensei, holding a large paper bag with two of his tentacles.
"Nuuhuhuhu~! Good morning, Hoshino-kun, Sendo-san!"
Akira blinked.
"You're early."
Koro-sensei's face shifted into proud yellow with green stripes.
"Of course! A teacher must support his students on their very first day!"
Erika quickly stood up and walked over, composing herself.
"Good morning, Koro-sensei."
Koro-sensei's tentacles wiggled happily.
"Good morning to you too, Sendo-san!"
Akira rubbed the back of his neck.
"You can just call me Akira. And she's Erika."
Erika nodded.
"Yes, please drop the honorifics."
Koro-sensei's eyes narrowed slightly as he observed the two of them.
The awkward atmosphere.
Erika's lingering blush.
The way they unconsciously stood closer together than usual.
…
His smile widened.
"Nuuuh? Did I come at a bad time? There seems to be quite a romantic tension in the air~"
Akira answered immediately without thinking.
"Nothing romantic. We were just discussing how to deal with her biological needs."
Silence.
Absolute silence.
Erika's face instantly went from pink to bright crimson.
She moved like lightning and wrapped her arm around Akira's neck in a chokehold.
"AKIRA—!!"
"W-wait, Erika—!"
Akira struggled weakly while being strangled.
Koro-sensei's tentacles flailed in complete shock.
Akira quickly added through the chokehold,
"Eating and drinking are biological needs too, you know!"
Koro-sensei froze for a second.
Then realization dawned on him.
His color slowly shifted into soft pink.
"I see… Well, as a teacher, I naturally support all forms of youthful romance, but perhaps the two of you should take things slowly? Building a proper relationship step by step is important, you know~"
Erika's grip tightened even more.
"Koro-sensei, please stop encouraging him!"
Desperate to escape this nightmare, she quickly changed the subject.
"By the way… why exactly are you here?"
Koro-sensei brightened immediately and lifted the large paper bag.
"I brought your Kunugigaoka uniforms and the other necessary items! A teacher must properly support his students on their first day!"
Erika accepted the bag with a small bow.
"Thank you… But how did you know our measurements?"
Akira answered casually,
"I gave them to him yesterday."
Erika slowly turned toward him.
"…And how exactly do you know my measurements?"
Akira blinked innocently.
"It's basic math. Just by looking. Your three sizes are—"
Erika instantly slapped a hand over his mouth.
"Don't you dare say them out loud!"
Koro-sensei watched them with sparkling eyes and clapped two tentacles together excitedly.
"Nufufufu~ You two really get along nicely!"
Erika's eye twitched.
Once again, she desperately changed the subject.
"Umm… could you tell us more about the school? Especially Class 3-E?"
Koro-sensei immediately launched into a cheerful explanation.
He spoke about the school's strict hierarchy, the discrimination against E Class, the isolated mountain campus, and gave them a brief overview of their future classmates.
He talked warmly about every single student—
while also describing assassination attempts in way too much detail.
After finishing, he checked the time.
"The school day will begin soon! Please don't be late on your first day!"
Then, with a cheerful—
"Nuuhuhuhu~!"
—he vanished in a burst of Mach 20 speed, leaving behind only a gentle breeze.
The moment he disappeared, Erika grabbed Akira by the shoulder with terrifying force.
"…Akira."
Her smile was calm.
Too calm.
"Let's have a talk."
Inside the old wooden building of Class 3-E, the students gathered before homeroom were chatting in a mix of curiosity and suspicion.
Nagisa sat near the front, listening quietly as the conversation flowed around him.
"New transfer students, huh…" he murmured, fiddling with the end of his braid. "At this point in the year… that's pretty unusual."
Karma leaned back lazily in his chair, arms behind his head with a grin.
"If they're transferring into this class, they're definitely not normal. Either they pissed off the principal really badly… or they're here for the same reason as Bitch-sensei."
Nagisa turned around in his seat.
"Karma-kun, are you saying they're assassins like her? Hired by the government?"
Karma shrugged with a smirk.
"Who knows? Maybe."
Kayano's eyes sparkled with curiosity.
"I wonder if the new girl is cute! It'd be nice to have another girl in class."
Okajima immediately clasped his hands together dramatically.
"Please let them be cute girls~! Onee-chans, bless us with beautiful transfer students!"
Sugino laughed awkwardly.
"Why would anyone willingly transfer into E-Class anyway? It doesn't make sense."
Isogai, ever the responsible one, crossed his arms with concern.
"I'm more worried about whether they'll be able to handle this environment. If they're normal students, this place is going to be rough for them…"
Terasaka snorted from the back of the room.
"If they're weak, they'll just drag us down. And if they're strong, they better not act cocky."
Then—
The classroom door suddenly slid open.
"Nuuhuhuhu~! Good morning, everyone!"
Koro-sensei entered dramatically as always, tentacles waving cheerfully.
"Before we begin homeroom, I have exciting news! Today, we have VERY special transfer students joining us~!"
The entire classroom fell silent.
Nagisa immediately raised his hand.
"Koro-sensei… are they assassins?"
Koro-sensei's face shifted into a playful grin.
"Fufufu~ You'll see soon enough."
He turned toward the classroom door.
"Now then, let me call them—"
BZZZZZT—!
A loud burst of static exploded from the classroom speakers.
Then—
The iconic opening guitar riff of Il Vento D'Oro blasted through the entire school at maximum volume.
The dramatic music echoed across the mountain like the entrance theme of an anime final boss.
Teachers in the main building looked around in confusion.
Students stared upward at the ceiling.
Even Koro-sensei froze mid-tentacle.
"Nuuuh…? This isn't the normal school broadcast…"
But the music didn't stop.
It only grew louder and more dramatic.
Then—
The classroom door slowly slid open.
A single leg stepped inside.
Black shoes.
Perfectly pressed dark grey Kunugigaoka uniform pants.
And an aura of complete, unreasonable confidence.
Akira had arrived.
The piano section of Il Vento D'Oro dropped dramatically, turning the entrance into something straight out of an anime opening.
Akira walked in slow motion.
He had an extraordinarily handsome face—sharp yet elegant features that almost seemed unreal. His hair was pure white, shining under the morning light, and his eyes were a striking star-like purple that faintly glowed with an otherworldly radiance.
Every step was deliberate, perfectly synchronized with the music.
His posture was straight and confident.
And his dark grey Kunugigaoka uniform fit him perfectly.
Most of the class stared in complete silence.
The girls instantly had stars in their eyes.
"Woah… he's actually really handsome…"
"So cool…"
Karma's grin widened immediately, eyes sparkling with interest.
"Now this is getting good."
Nagisa blinked several times, clearly confused but somehow unable to look away.
"…It looks cool, but… why is he walking in slow motion?"
Meanwhile—
Erika simply walked past Akira at completely normal speed.
Elegant and composed as always, she didn't even glance at him.
She had fully abandoned her boyfriend to his theatrics like she had never met him in her life.
Akira continued his slow-motion walk all the way to the front of the classroom.
The moment he stopped beside Koro-sensei—
the music abruptly cut off.
Silence returned instantly.
Koro-sensei's tentacles froze mid-air, visibly impressed.
"Nuuuh… that was certainly quite the entrance! But tell me, Akira-kun… did you hack the school speaker system?"
Akira tilted his head innocently.
"I have no idea what you're talking about. Anyway, there's no proof."
The entire Class 3-E collectively had the exact same thought.
What the hell? This guy is insane.
Koro-sensei let out a long sighing "Nuuuh…" before clapping two tentacles together.
"Fufufu~ Everyone, allow me to introduce your new classmates! First, Sendo Erika."
Erika stepped forward gracefully and gave a polite bow.
"My name is Sendo Erika. I look forward to studying with all of you."
The class responded warmly—
especially the girls.
Then Koro-sensei gestured toward Akira.
"And this is Hoshino Akira."
Akira immediately struck a dramatic pose.
"I am Hoshino Akira, from the Village Hidden in the Stars. I have come to this world to save it from destruction and fulfill my destiny as the destined one—"
Before he could continue any further, Koro-sensei hurriedly interrupted.
"Alright, that's enough for now! Please go sit down before you say anything else~!"
Akira shrugged casually and scanned the classroom.
Then his eyes locked onto a seat near the back by the window.
"That one," he declared confidently. "The window seat. It is the throne of protagonists, and as the ultimate protagonist, that rightful place belongs to me."
Erika sighed softly but followed him without complaint, taking the seat directly beside him.
The moment both of them sat down, Koro-sensei's cheerful expression returned.
"Now then! Let us begin homeroom attendance—"
The instant those words left his mouth—
every single student in Class 3-E moved.
Without hesitation, the entire class pulled out anti-sensei weapons.
Guns.
Knives.
Specialized assassination equipment.
All of it immediately aimed toward the front of the classroom with deadly serious expressions.
This—
was their official welcome to the End Class.
