The following morning, Momo walked through the gates of U.A. beside Junsei, who carried his usual backpack, along with a neatly wrapped sleeping bag slung over his arm.
Momo glanced at it, disbelief plain on her face. "I can't believe you're really bringing this with you."
Junsei did not look at her. "Again, it is fine."
"You're going to get in trouble," she insisted.
"There's no rule against it," Junsei replied evenly. "And somebody else is already doing it."
Momo stopped short. "That's my classroom teacher!!"
Junsei continued walking, clearly finished with the discussion. Momo let out a small sigh and followed, wondering, as she often did, whether a day would ever come when Junsei might behave like a normal person. At the entrance to the main building, they parted ways, each heading toward their respective classrooms.
When Junsei stepped into Class 1-C, the students already seated turned to look at him. Their gazes lingered on the strange, wrapped object in his hand. No one could quite tell what it was, only that the silent, emotionless boy was carrying something unusual. Curiosity flickered in the eyes of some, but not a single student stepped forward to ask.
Shinso, seated beside Junsei, cast him a brief sideways glance, eyes narrowing slightly with interest, but he said nothing. The lessons began soon after, and the day proceeded as normally as any other.
The class before lunch was Modern Literature, taught by Cementoss.
When the bell rang to signal the end of the period, Cementoss turned from the board.
"Good work, everyone. We shall continue tomorrow. Mori Junsei, stay behind. I would like to have a word with you."
The students filed out one by one, each stealing a glance back at Junsei, murmurs barely contained. Junsei remained seated, his expression unchanged.
Cementoss waited until the room was empty before speaking. "I was informed that yesterday you went onto the roof, which is against school rules for students."
Junsei said nothing, merely waiting.
Seeing no response, Cementoss continued. "You are still new here, so we will overlook it this time. But more importantly, regarding All Might and what you saw, it is imperative that you do not share this information with anyone."
Junsei finally spoke. "He said that."
Cementoss blinked. "And? Did you tell anyone?"
"No," Junsei replied calmly. "I don't want to provoke him."
Cementoss frowned, momentarily thrown off. Provoke All Might? It was a strange way to speak of the Symbol of Peace.
Recovering quickly, Cementoss straightened. "I am glad you understand the importance of this. Keeping such a secret is as important as any hero work being done out there."
The words were clearly meant to awaken the sense of heroism inside Junsei. Instead, his face remained blank, untouched by the sentiment.
Cementoss studied him for a long two seconds before sighing. "That is all I wished to say. You are free to join your classmates."
Junsei stood, but rather than heading for the door, he calmly unfolded the wrapped bundle. Before Cementoss's bewildered eyes, he spread the sleeping bag behind his desk and slipped inside it.
Cementoss blinked. "What… what are you doing?"
"Sleeping," Junsei replied.
"You plan to sleep through the lunch period?" Cementoss asked slowly.
"Is there a rule against it?" Junsei asked back.
Cementoss hesitated. "I… I am not sure. But don't you want to go out, eat, and talk with your classmates?"
"I would rather not," Junsei answered, pulling the sleeping bag closed in a clear dismissal.
Cementoss stood there for a moment longer, staring at the now motionless shape behind the desk, before turning and leaving the classroom, more confused than he had ever been by a student in all his years of teaching.
When the lunch period ended, the first student to return to Class 1-C was Shinso. He walked straight to his desk and reached for his chair. It was only then that he noticed something bulky and unfamiliar behind it.
He froze.
Blinking, Shinso stared down at the neatly laid sleeping bag.
"What is going on here?" he asked slowly.
The bag rustled. A moment later, the zipper slid open and Junsei looked out at him, blue eyes calm and unreadable. The two stared at each other for a second, an odd, silent exchange passing between them.
"The lunch period is over?" Junsei asked.
"Yes," Shinso replied. "What were you doing?"
"Sleeping."
As if that explained everything, Junsei stood up, stepped out, and began rolling the sleeping bag. He tucked it aside and sat back down at his desk, expressionless as ever, leaving Shinso standing there in open bewilderment.
Shinso glanced at the wrapped bundle again, then at Junsei, then back at the bundle. His eyes lingered on it with growing interest, though he said nothing.
Soon after, the rest of the students filed in. None of them noticed anything unusual, unaware that one of their classmates had spent lunch asleep in the classroom. The day continued without incident.
The next morning, however, the class was greeted with a surprise.
Shinso entered carrying a wrapped bundle, nearly identical to Junsei's.
Junsei noticed it immediately but made no comment.
When lunch came again after Modern Literature, the students began rising from their seats, chatting as they prepared to leave. At that exact moment, Shinso and Junsei moved in perfect synchronization. Together, they unwrapped their sleeping bags.
The room fell into stunned silence.
Before anyone could say a word, the two slipped inside their bags and zipped them shut, ignoring the world entirely. Whispers erupted around the room.
Cementoss, who had not yet left the classroom, stared in disbelief.
"There are two of them now!!" he muttered. "What is wrong with this year?"
A dreadful thought crossed his mind, of more students joining in, of Class 1-C becoming known not as General Education, but as the class that naps.
Deciding this was far beyond him, Cementoss left the classroom, already planning his next steps.
That same afternoon, he entered Principal Nezu's office, where Eraser Head and All Might were already present.
"I hope I'm not interrupting," Cementoss said.
Nezu waved a paw. "Just a routine report on the hero course students. What can I help you with?"
Cementoss cleared his throat. "Actually, something strange is happening in my class. Mori Junsei brought a sleeping bag yesterday and slept through the lunch period."
Three pairs of eyes lifted in interest.
"And if it ended there, I wouldn't be concerned," Cementoss continued. "But today, another student brought a sleeping bag and slept alongside him. I don't know what's going on or whether I should stop it. I've never encountered anything like this."
Eraser Head frowned thoughtfully. "Mori Junsei… the boy with white hair and sky-blue eyes?"
"Yes," Cementoss replied.
All Might turned to Eraser Head. "You've met him?"
Eraser Head sighed. "That troublesome kid wandered into my class while I was sleeping and started asking stupid questions about my sleeping bag. It never crossed my mind he'd bring one to school."
Nezu chuckled softly. "Well, isn't he a funny one? He saw a teacher sleeping and decided to do the same. Most likely, it's his way of avoiding other students."
All Might frowned. "This is no laughing matter. We need to help him integrate, not isolate himself further. He's even drawn another student into this."
Nezu tapped his paws together. "I'd say it's a form of bonding, but I agree, we can't have students sleeping in classrooms like this. Starting tomorrow, we'll introduce a new rule: all students must leave their classrooms during lunch unless they have a study-related reason to stay."
He smiled. "Let's see how they react."
The trio exchanged glances, each quietly suspecting that their principal was enjoying this situation far more than he should.
The next day, in Class 1-A, all the students were seated when Eraser Head addressed them in his usual tired voice.
"Before we start the day," he said, "there's a new rule introduced this year, and all students are required to follow it."
The room immediately got silent. Even Bakugo paused to pay attention now. A new rule in the first week of school must be because of something significant.
Eraser Head let the silence stretch before finally saying, "During the lunch period, you are not allowed to stay behind in the classroom unless it's related to learning."
Confusion rippled through the class. The rule sounded oddly specific, and to most of them, completely pointless.
Iida shot his hand into the air. "I don't understand the purpose of this rule! Why was it introduced?"
Eraser Head glanced at him. "Some troublesome students in Class 1-C decided to bring sleeping bags and sleep in school."
For a moment, no one spoke.
"Students?" Momo asked slowly. "As in… more than one?"
"Yes," Eraser Head replied flatly. "A student named Mori Junsei started it, and another followed. The school got concerned we'd end up with an entire class sleeping through lunch."
Momo covered her face with one hand in pure exasperation. Around her, the students who had already met Junsei turned to stare at her in open surprise.
Mina leaned back in her chair, grinning. "He's a prodigy all right. UA introducing a new rule because of him in the first week? That's impressive."
"Please stop," Momo said weakly.
Eraser Head raised an eyebrow at the exchange but didn't bother commenting. He clearly didn't care.
At the same time, in Class 1-C, students slowly turned their heads toward Junsei and Shinso as their homeroom teacher announced the same rule. Junsei remained completely expressionless. Shinso frowned slightly, clearly displeased. Still, the day moved on, and before long, the rule faded into the background of lessons and classes.
When lunch finally arrived, Shinso turned toward Junsei.
"So," he asked, "what are you going to do now?"
Junsei looked at him calmly. "Sleep."
He picked up his sleeping bag and walked out of the classroom. Shinso blinked, hesitated, then grabbed his own and followed.
A minute later, the two stood in front of Class 1-A. Shinso looked confused, while Junsei simply peeked through the window. Spotting a familiar sleeping bag inside, he opened the door and entered.
Junsei walked straight to the back of the room. Shinso followed after a moment, uncertainty written all over his face.
Eraser Head opened one eye. "What do you two think you're doing?"
"We can't sleep in our classroom," Junsei said calmly.
Eraser Head raised an eyebrow. "So you come to another class?"
"It's not against the new rule," Junsei replied.
"Why here?"
"Because you're here," Junsei said. "No one will annoy us with a teacher sleeping with us."
Eraser Head stared at him. Then at Shinso, who looked increasingly nervous.
"I am not paid enough for this," he muttered, pulling his sleeping bag shut.
Junsei unfolded his own and climbed in. After a brief pause, Shinso did the same.
Three sleeping bags lay still.
When lunch ended and Class 1-A returned, they froze at the sight before them. Three identical shapes lined the classroom floor. Students gathered, staring from one bag to the next in disbelief.
Momo's eyes landed on one in particular. "What are you doing here?"
Junsei opened his bag and looked at her. "Sleeping. Is lunch over?"
"Yes," Momo said faintly.
Junsei stood and folded his sleeping bag. Shinso followed a few seconds later. Without another word, the two left the classroom, passing the speechless Class 1-A.
Kirishima finally spoke. "What just happened?"
Eraser Head unzipped his bag. "Take your seats."
"But what about…" Kirishima began.
"We'll have a new school rule tomorrow," Eraser Head interrupted.
Mina snorted. "Two rules in one week? That's gotta be a record, right?"
Momo silently prayed that Junsei wouldn't be expelled for his antics.
At the start of the second week of the school, a new rule was introduced at UA: Students are strictly prohibited from bringing sleeping bags onto school grounds.
