i.
It surprised everybody that Bakugou accepted the Homeroom and Heroics position that Aizawa used to occupy. After Principal Nedzu retired (and became the resident cryptid), Aizawa was the main candidate for becoming the new Principal. Aizawa accepted, but the other thing that was surprising was that he invited all 20 of his ‘hell children’ to come teach.
Some people were pretty much expected, like Yaoyorozu coming to teach art history for the Hero Course, Shinsou teaching math for Gen Ed, and Iida teaching English for the Support Course.
Which comes back to how nobody expected Bakugou to come teach.
(Except for Midoriya, he always knew Kacchan was a good teacher.)
Aizawa decided that the new first-years shouldn’t know before hand who their teachers are, ’logical ruse!’, so Bakugou was taking full advantage of that fact by arriving right when homeroom started.
Bakugou could hear the rustle of backpacks and the loud voices of his students. Some were talking about the entrance ceremony, others were wondering where the teacher was, and even others were speculating on what the actual teacher lineup would be. Bakugou thought of his plan to instill fear into his students when he arrived at the building, and was grinning like an animal when he kicked the door in.
“HELLO DIPSHITS!” Bakugou yelled as the door slammed open, quieting every student as his foot slightly cracked the floor. Bakugou walked towards the desk, turning to write his hero name and his civilian name on the board. “I’m your fucking homeroom and Heroics teacher, Bakugou Katsuki, or Great Explosion Murder God Dynamight. Fuckin’ call me Bakugou-sensei.”
Bakugou turned back around, seeing how all 20 of his students looked like deer in headlights. Make that 19, because Izumi Kouta spoke up.
“You’re our teacher? Fucking bullshit, the only person in Class 3-A that has their shit together is Tsuyu-chan.”
Class 1-A looked horrified at Kouta, reacting like he threw a bookshelf at a bomb. To everyone’s surprise, Bakugou barked a laugh and replied, “Damn straight, kid. Don’t worry, Frog-Face is gonna teach you too.”
The students looked even more horrified. ’Frog-Face?’
ii.
Aimi Suzuki didn’t know what to expect from U.A., but it certainly wasn’t Bakugou-sensei. He gave everyone crude nicknames (he named Suzuki ‘Jean Fucker 2’ because she could control fabric. Who the original Jean Fucker was, she didn’t want to know), laughed when they swore at him, and pushed them to their limits.
Okay, maybe that last one was a good thing in the long run, but Suzuki’s body did not appreciate it.
“Everybody get the fuck up! My class had a villain attack on the fourth day of school, and this ain’t shit compared to that! Quirks are like muscles, fucking use it more and it gets stronger!”
Suzuki’s body definitely did not appreciate it, especially because she knew that Bakugou-sensei was going easier on them than Aizawa-san did when he taught Bakugou-sensei.
It seemed like the rest of the class took that a different way, because most of them paled at the mention of a villain attack and started working Plus Ultra.
“Hell yeah, that’s what I like to fuckin’ see! Jean Fucker 2, copy the rest of your class and go Plus fucking Ultra!”
“Yes, Bakugou-sensei!”
Hayashi Komura (who had a mutation-type tiger quirk, so he was working on strength and endurance) spoke up and asked, “Oi, Bakugou-sensei! How many villain attacks did your class have? The news shut up about it after the second one.”
Bakugou-sensei seemed to think on it for a moment, then said, “All of them? I think there were 11 in total, spanning my 3 years. I also had to go fucking find my bullshit extra who went vigilante, so 12 I guess?”
If everyone was pale before, then they all became ghosts. Suzuki couldn’t believe it. 11 villain attacks plus finding a classmate who became a vigilante?
There really were way too many reasons to go Plus Ultra.
iii.
Ikeda Mori was generally an easy-going person. Spring something on her last minute? No problem. Dropped her phone and it cracked? Fine. Awful breakup and you need her? Had ice cream ready yesterday.
But nothing could prepare her for today.
Class 1-A had been chattering away like usual, waiting for Bakugou-sensei to kick the door in and brief them on the day. It was going to be a normal day. Right?
Wrong.
When Bakugou-sensei kicked in the door and ‘greeted’ them, nobody stopped talking. Of course, some people did (Kouta-kun and Suzuki-san as well as herself) but all the loud people somehow ignored Bakugou-sensei.
Bakugou-sensei grew increasingly more volatile, looking angrier by the minute, until his patience entirely snapped 5 minutes before homeroom ended.
He let off a powerful explosion and everyone quieted (Mori’s ears were ringing, but she felt like it wasn’t the greatest time to bring it up).
Bakugou-sensei never spoke up from a whisper, but it was the loudest words Class 1-A heard all year.
“Everyone except Mori, Suzuki, and Kouta are expelled.”
Everyone was silent, stunned in shock.
Bakugou-sensei now spoke in a normal talking voice, “If you can’t hear me kick down the door and yell ‘Hello dipshits’, then you will most certainly die on the field. You don’t want that, I don’t want that, and Aizawa-san definitely doesn’t want that to happen, again. Understand?”
Everybody nodded feebly, scared shitless.
“If you don’t want to be expelled, take it up with Aizawa-san. He’ll probably tone down the expulsion to 2 months without Heroics classes. This isn’t going to happen again. Got it?”
Class 1-A collectively nodded, with more energy this time. They had a second chance, and they weren’t going to waste it.
Mori’s respect as well as fear for Bakugou-sensei just skyrocketed.
iv.
When everybody’s (except Kouta, Suzuki, and Mori) 2 month ban from Heroics classes ended, Bakugou-sensei took them to the USJ.
Ishii Yamazaki was happy as well as scared for the field trip that day. He knew that the USJ was the place where the first villain attack from the League of Villains happened, so coming to that location likely held trauma for Bakugou-sensei. But he was also excited, because it was mainly about search and rescue, and Yamazaki wanted to become a Rescue Hero with his cotton-creation quirk.
Bakugou-sensei ushered Class 1-A onto the bus, and was silent the entire time. Understandable, Yamazaki thought.
When they got off the bus and started walking inside, Bakugou-sensei stopped them.
“Alright, listen up. All you fuckers know that this place is where the League of Villains first attacked, when I was a first-year like everybody here. Even though there probably aren’t villains in there, keep a high guard. Anyway, this place is for learning search and rescue. Now, I’m not a rescue hero, so that’s why we’re having Uravity join us.”
Everyone cheered, Yamazaki especially. He was going to meet Uravity, the Gravity Hero! One of the highest-ranking Rescue Heroes!
“Oi, Round Face! We ain’t got all day!” Bakugou-sensei yelled into the USJ.
“Shut up, Bakugou! You try floating up stairs in heels!” A voice yelled back, which Yamazaki identified as Uravity’s.
Uravity came into view at the top of the stairs, smiling as she looked over everyone in their hero costumes.
“Hi everyone! My hero name is Uravity, but please call me Uraraka-sensei! I’ll be helping you learn rescue drills with your classmates, while Bakugou over here will watch over us in case there are villains or somebody actually needs help. Okay?”
A chorus of “Yes Uraraka-sensei!” erupted from Class 1-A.
“Great! Now everybody-“
“Uraraka!” Bakugou-sensei shouted. “Villains! Get the students to safety!”
Uraraka-sensei paled. “Everybody! Run to the entrance as fast as you can!”
Everyone ran with the core and essence of PLUS-MOTHERFUCKING-ULTRA until they made it outside.
Komura-kun spoke up and said, “What about Bakugou-sensei?”
Uraraka-sensei grinned evilly. “What about him? He’s the Number Two Hero for a reason.”
Yamazaki’s jaw dropped. Hero rankings generally weren’t public knowledge after All Might died, because the Hero Commission felt like it would put some heroes in unnecessary danger. They still told the masses if a particular hero was ranked high or low, but the specifics were limited to actual heroes with a license.
But still! Yamazaki was being taught Heroics by the Number Two Hero! Yamazaki briefly wondered who the Number One Hero was, but then the USJ’s main door swung open, showing a smoking but otherwise okay Bakugou-sensei.
“Villains didn’t know what hit ‘em.” It was Bakugou-sensei’s turn to grin evilly.
Villains and aspiring heroes alike now held another healthy dose of fear for Bakugou-sensei.
v.
Bakugou-sensei was angry today.
Now, he was normally angry when Class 1-A saw and interacted with him, but today he was particularly angry, and nobody knew why.
Teachers and students alike were falling over themselves to get out of Bakugou-sensei’s way to the classroom for Class 1-A.
When Bakugou-sensei kicked open the door, the floor cracked like it did on the first day, and Bakugou-sensei’s normal yell was louder than usual.
Suffice to say, Ezume Nakeno was eager to both figure out what made Bakugou-sensei so angry and to not bother him at all. The problem was, those were completely opposite goals. Nakeno wanted to keep his lifespan long, so he chose the latter.
Apparently, Kouta-kun did not have self-preservation instincts, so he kindly asked what was wrong.
“Bitch, what’s with you and your sucky mood today?”
Bakugou-sensei glared at him, before replying nasally, “‘M fucking sick. However much I want to stay home, I gotta teach you dipshits. Alri-“
Aizawa-san opened the door and glared at Bakugou-sensei. “Bakugou, go home. You’re sick. I’ll call Problem Child to sub for you.”
Bakugou-sensei glared in turn at Aizawa-san, but Bakugou-sensei’s glare was a mixture of surprise and.. fear? Who exactly was ‘Problem Child’?
Bakugou-sensei eventually replied, “Thank fucking god,” then stood up and left the classroom.
Aizawa-san then turned to look at Class 1-A. “Problem Child will be here in 5 minutes. Don’t break anything.” Aizawa-san accentuated the latter sentence with his famous glare. It definitely worked, because everyone went silent.
Class 1-A not-so-eagerly awaited whoever managed to make Bakugou-sensei, the scariest teacher on campus, afraid of them.
+1.
When the door slid open, Class 1-A was expecting a tall, muscly, fear-inducing-at-first-sight person. Definitely not a 5’ 5” guy with a baby face wearing a hoodie and sweatpants. The guy walked up to the teacher’s desk before turning to only write his civilian name on the board.
“Hi everyone! My name is Midoriya Izuku, and I’ll be subbing for Kacchan today! I’ll be your Heroics and homeroom teacher for today, so please call me Midoriya-sensei!”
Hideyo Fujiwara didn’t know what to think of Midoriya-sensei. He managed to make Bakugou-sensei scared of him, but Fujiwara didn’t even know if Midoriya-sensei was a Pro Hero. He calls Bakugou-sensei Kacchan! Fujiwara kept his observations to himself, but his classmates (except for Kouta, apparently) openly questioned Midoriya-sensei.
“Are you even a Pro Hero?”
“Why do you call Bakugou-sensei Kacchan?”
“Why is Bakugou-sensei scared of you?”
“You don’t look very intimidating.”
Midoriya-sensei smiled at the incoming questions, until one particular statement caused him to drop it.
”You don’t look very useful.”
Midoriya-sensei slammed his hand onto the table, causing everyone to quiet down. He smiled again, but it felt like all the warmth in the room was sucked out with a vacuum.
“Would you all like to know what my hero name is?” Midoriya-sensei asked. His tone sounds like it should be happy, but feels like icy daggers glaring into everyone’s skin instead.
Midoriya-sensei turned around again, picking up the chalk as he wrote two symbols in large, blocky letters.
デク
Deku.
Midoriya-sensei was Deku.
Midoriya-sensei was the Deku that had six quirks, the Deku that took down Shigaraki, the Deku that was the Symbol of Hope.
The Deku that was the Number One Hero before the rankings were hidden.
That Deku.
Class 1-A was screwed.
“I hope that every time someone new comes into the classroom, it isn’t like this. Now, let’s continue.”
The warm atmosphere came back into the room, but nobody felt deserving of it. Nobody felt deserving of Midoriya-sensei smiling as he wrote down the schedule for that day. Midoriya-sensei stopped as he wrote down what was going to happen for Heroics that day, before he turned around.
“Change of plans. For Heroics today, It’ll be a 20v1. Me versus you all. I hope you won’t hold back!”
Midoriya-sensei smiled, as Class 1-A screamed.
