Ultimate move: Random refrence!

_____________________________

"Maybe this isn't the win-win I was thinking." I massaged my chin after a huge realization, I only have 1 bed.

"Are you sure this is a good idea? You can just leave," I tried convincing Jiro that we can't just sleep on the same bed. Even after I offered to sleep on the couch.

"I can't make our first night in the dormitory uncomfortable. And if Mr Aizawa catches me leaving your bedroom" Jiro's face went red just from the thought.

"..ugh fine" I relented and let Jiro stay here just for today. You know maybe this isn't so bad....

......

'okay scratch that, this is very bad' I stared at the ceiling of my bedroom now in PJs I finally understood why women view many people as perverts. Just the sound of the shower is making my head blank.

I pushed aside my lightly wet hair and massaged my forehead. I would have a gigantic headache after this...

I pulled out my phone and began scrolling down on those 'shorts' videos, degenerating my attention span so I could try to ignore what was rising and it wasn't the shield hero.

...

After what seemed like 10 minutes the sounds of running water stopped, snapping me out of my cute cat videos. I calmed my beating heart and decided to relax.

"Alright Rimuru I'm done-"

"Lord have mercy on my mortal soul" I put a hand on my chest as I felt my nose bleeding. Jiro decided to only wear an oversized shirt and panties covering the important bits. However, it had the unintended effect of being hella hot.

"S-stop staring... It's how I normally sleep" Jiro felt as if Rimuru's gaze was stripping her of her privacy, quickly regretted her stupid impulsive decision.

"S-sure just let's go to sleep already..." I patted the spot next to me as my bed wasn't big enough to fit the two of us comfortably.

Feeling Jiro getting close to me under the covers made my breath hitch, I calmed down my nervousness and tried getting to sleep and Ignoring the increased blood flow.

Needless to say, both Rimuru and Jiro could not sleep that night. One was way too nervous and the other was constantly getting poked in the back.

*************************************

*Knock knock knock*

"Jiro wake up!!!!" Mina knocked on Jiro's door while Uraraka shouted, they both stopped and looked at each other.

"Do you think she's sleeping?" Uraraka asked, Mina rubbed her chin while thinking.

"Do you think she forgot to unpack her alarm clock?" Mina herself forgot to pack her alarm clock, due to its constant abuse it was barely even scrap metal that made noise.

"Hmmm... Maybe should we get Aizawa to unlock her door? He said something about a master key" Uraraka questioned however their gaze shifted to the other side of the hallway where one of the doors had just opened.

"Next time you decide to poke me I might just twist it off" a complaining voice was accompanied by a yawn.

"Hey relax it's a biological reaction" a tired gruff voice replied, Mina and Uraraka looked at the name on the door. Seeing it was Rimuru's a small smirk formed on both their faces.

"How shameful"

"How bold"

As soon as Rimuru stuck his head into the hallway his ears caught their murmuring, instantly flinching he rubbed his eyes before sighing.

"Why do people always assume " Yawning yet again he took a step into the brightly lit hallway making him squint quickly. Without wasting any time Rimuru began making his way to the communal bathrooms to brush his teeth.

"Oui wait for *yawn* for me" Jiro hopped out of Rimuru's dorm room, bags under her eyes.

*************************************

"I'm so tired" I laid my head on my seat while complaining, my vision was blurry as I didn't get a wink of sleep. Pinching my arm I tried to keep awake.

"We're you also too excited to sleep?" Midoriya turned towards me, heavy bags under his eyes however he seemed to be as energetic as ever.

"Yeah, sure..." I didn't correct Midoriya as fixing the misunderstanding that might come from honesty would be a pain in the a**.

"Shuddup already, if you can't sleep then go die" Bakugo who was seated between the two shouted in annoyance, his legs resting on the table as if he didn't care.

"Bakugo how many times do I have to say-" As Iida was about to reprimand Bakugo the door opened with All Might smiled as usual. His cape fluttered however some might notice he didn't close the door... Strange..

"Hello young heroes, I'm sure everybody is excited about the dormitories, however, that doesn't stop us from learning to be a hero!" All Might raised his fist in the air. stars shone in some of the student's eyes.

"What will we be learning?" Kirishima raised his hand in the air, a menacing grin on his face. Heroics class with All Might was his favorite class..

Pshhh training junky.

"Good question Kirishima-shouenen" All Might pointed at him before turning back to the board, waving a chalk that appeared out of nowhere he began writing on the board.

[Ultimate Moves]

Tapping the chalk one last time All Might turned back before announcing.

"Today we will be learning Ultimate Moves! But we will also have a very special guest!" All Might announced before pointing at the door.

Because I already knew what this class was about I decided to take my time napping. I already have a few ideas for Ultimate moves. Like my [Beelzbub] domain could be a cool one. Maybe black lightning too..

*Clank clank*

Feeling my hair stand on the back of my head I was snatched away from dreamland, the sounds of high heels gave me a strange feeling.

"Allow me to introduce you to Julia Tempest! Also known as former 34# pro hero Tempa!" All Might waved his hands in an exaggerated gesture.

Soon a figure entered the class. some of the boys' eyes popped out of their sockets. An absolute bombshell of a lady entered the classroom. With dark blue hair and crimson eyes that could captivate even the purest of men.

However, a strange silence spread throughout the classroom.

"Huh? Tempest?" Everyone's gaze shifted between Rimuru and Julia. Rimuru stared strangely at his mom as she smirked cheekily back at him.

"H-hi mom" Rimuru averted his gaze as he openly admitted to being a pro hero's kid... Wait isn't Shoto Endeavor's kid?

"Alright everyone, let's go to the training field, where we'll be making your new Ultimate moves" Julia clapped her hands, a small smile on her face.

Kaminari was drolling all over his desk, her voice serenading him. Just one 'Ara Ara~' and he will need a new change of pants.

****************************************

(A/N: info dump ahead!)

Julia Tempest. Quirk: thermokenisis.

She can store the thermal energy of objects around her in her own body. Although the actual range of her quirk is unknown it is big enough to freeze an entire block.

By absorbing all the energy from an object she can even freeze even the air itself, on the opposite side by dumping all the energy onto an object it could melt steel.

The most overpowered aspect of her quirk is the lack of a limit for her thermal storage. The only thing keeping her from being a miniature sun is the leakage of energy. If she can't control the energy anything in her vicinity would turn to ash.

Of course, due to the nature of her quirk, she has natural thermal vision and it's suspected she can passively sense the amount of energy objects around her has.

Midoriya closed the page of his notebook, his notes on Tempa varied as he believed her quirk had almost limitless potential.

"Alright everyone, now let's get onto the main topic. What is an ultimate move?" Tempa asked the students, seeing as some hands were raised a small smile formed on her face.

But she noticed Rimuru wasn't paying attention, a quick singe of his nose snapped him out of his stupor.

"Yes, Iida-chan" Tempa picked the boy wearing glasses, luckily she memorized the name list and could connect names to appearance.

"Ultimate moves are big moves that usually aim for guaranteed capture" Iida's glasses glinted as he said respectfully.

"Half right. Ultimate moves are just big moves. Sometimes Ultimate moves just aim to clear debris for rescue. Sometimes of course they are extremely destructive"

Tempa turned around to a gigantic 20x20 block of concrete that took up space in the middle of the arena. Courtesy of Cementoss.

"Now here's an example [Ultimate Move: Blazing Sun]" Tempa pointed her finger at the block of concrete, as soon as she did a gigantic web-like crack appeared all over the block before it exploded into liquid lava.

Everybody had their eyes open wide as they gazed at the now liquidized block. They were impressed by the strength of her quirk. However Midoriya of course started analyzing.

"Now of course not all moves have to be this flashy or destructive, but remember to make sure your Ultimate Moves are truly Ultimate!" Tempa clenched her fist in the air before the entire class said in unison.

"Go beyond plus ultra"

****************************************

The training exercises were quite simple, train as hard as you can and come up with moves strong enough to call ultimate moves. Bakugo started by trying to compress his sweat with no success.

Midoriya also seemed to be out of ideas as he just punched pillars of concrete down. Kirishima dug through a wall like a bulldozer trying to further harden his body.

Shoto tried to further the limit of his ice as he created gigantic glaciers, each bigger than the other. Of course, melting it right after

"That's no good" Shoto jumped back in fright as a voice came from behind him, seeing Tempa, the new teacher he relaxed.

"What's wrong" Shoto asked, he was annoyed she was judging him right now.

"Creating gigantic glaciers might be cool but the ice's temperature is too hot for it to be strong. It would melt back to water in 2 hours" Tempa noticed that Shoto's ice is much too warm for the ice to be strong enough. Shaking her head she energized the glaciers instantly turning them back to water.

"Now watch this" Tempa pointed at the floor where suddenly 2 ice cubes appeared on the floor. One looked like a regular ice cube while the other one emitted a misty cold aura, it was obvious which was cooler than the other as the misty ice cube froze the surrounding puddles.

Tempa walked forward before putting her foot onto the regular ice cube, with just a bit of pressure the ice cube broke. However, when she tried the same with the other ice cube it held onto her entire weight.

"The cooler the ice the stronger it is" Tempa pointed to Shoto who nodded while staring in awe, he realized being flashy could've gotten him caught in a pinch if future villains could easily break his ice.

************************************

"So Rimuu~ why aren't you doing anything?" Tempa finished teaching Shoto so she approached her lazy son who seemed to sit around.

"I've already come up with some Ultimate moves" Rimuru smirked cheekily, Tempa being the curious mother she was tilted her head.

"Do tell"

Rimuru stood up and wiped the dust off of his pants, walking towards a wall made of concrete, opening his palm an orb made of compressed [Bleezbub] smoke floated over. Concentrating on his control he made [Black Lightning] arc around the orb, closing his palm tightly he got closer to the wall

Simply swinging his fist at the wall made the orb explode into a cloud of arcing lighting and smoke, quickly devouring the wall as if it wasn't even there. If you were to blink it was as if there was a flash and the wall was gone.

"Wow" Tempa clapped while feeling proud of Rimuru, she always felt his quirk was as powerful as hers, maybe even stronger due to its destructiveness.

"So what do you name you new Ultimate move?"

"I'll call it [Black Flash]"
