Slight 18+ NSFW at the end

It has been 1 week since the U.A. Entrance Exams and both Flynn's and Jirou's letters have arrived at Flynn's mailbox since Jirou had moved in with Flynn at a random house that Flynn had purchased.

Flynn had just gone out of the house and collected the acceptance letters from U.A. He walks back inside the house.
"Hey Flynn, what's tha- oh my fucking god, are those letters from U.A.?!?!* Jirou exclaims.
Flynn nods, smiling, and hands her hers.
"You open yours first." Flynn states.
Jirou nods and gently unsealed the letter, reaching in and pulling out a strange disk. She sets it on the table, and it suddenly bursts to life with a hologram.
"I AM HEERE, AS A HOLOGRAM!" The hologram of All Might yells out.
Jirou tenses for a moment, still a little traumatized from the previous week before Flynn puts a hand on her shoulder, which manages to calm her.
All Might suddenly starts again,
"YOUNG JIROU, YOU GOT A SCORE OF 79 ON THE WRITTEN PORTION, PLACING 16TH OVERALL! NOT BAD! BUT ON THE PHYSICAL PORTION, YOU GOT A TOTAL OF 39 POINTS VILLAIN POINTS! UNFORTUNATELY THIS IS JUST BARELY OUT OF THE REQUIRED AMOUNT TO PASS!"
Jirou's heart drops, and she almost tears up, looking down. Flynn remains unbothered as he already figured that there was another portion to the exam.
"HOWEVER! THERE IS ANOTHER WAY TO GAIN POINTS THAT WE DIDN'T TELL ANYONE IN THE EXAM!" All Might shouted enthusiasticly.
Jirou looks up at this, and Flynn only smirks.
"ME AND MY FELLOW OVERSEERS OF THE EXAM WERE LOOKING FOR HEROIC ACTIONS! WHEN WE REVIEWED THE FOOTAGE OF EVERY CONTESTANT, WE SAW THAT YOU HAD SAVED 5 PEOPLE FROM GETTING SERIOUSLY HURT! THOSE WERE SOME HEROIC ACTIONS! THEREFORE WE AWARED YOU 25 HERO POINTS! PUSHING YOU WELL WITHIN THE REALMS OF PASSING! YOUR CLASS WILL BE CLASS 1-A! CONGRATULATIONS ON GETTING ACCEPTED INTO U.A. YOUNG JIROU! WELCOME TO YOUR HERO ACADEMIA!" With those final words, the hologram had shut off.
Jirou was tearing up from happiness.
"I-I-I got in.. I got in! I GOT IN!!" Jirou shouts in excitement and hugs Flynn tightly. Flynn smiles and hugs her back. After a minute of hugging, Jirou broke the hug.
"I-it's your turn, babe.. open your letter!" Jirou says to Flynn softly. Flynn kisses her on the forehead and opens his letter, the disk projecting yet another hologram of All Might.
"I AM HEEERE AND AS A PROJECTION! YOUNG TAGGART! ON THE WRITTEN PORTION OF THE EXAM YOU GOT 100% AND EVEN FOUND AND CORRECTED NEZU'S MISTAKES HE PUT IN! SKYROCKETING YOU INTO 1ST PLACE! VERY IMPRESSIVE YOUNG TAGGART!" All Might exclaims.
Jirou looks at Flynn shocked,
"F-first place!?! W-wow! And you even spotted mistakes the principal put in as a test! You're amazing.." She says, astonished, and she hugs Flynn.
All Might continues,
"HOWEVER, WHATS EVEN MORE IMPRESSIVE, WAS THE PHYSICAL PORTION! YOU SCORED A TOTAL OF 107 VILLAIN POINTS! MORE THAN ENOUGH TO PUT YOU INTO 1ST PLACE AND MAKE YOU THE REPRESENTATIVE OF 1-A! HOWEVER, YOUR HEROIC ACTIONS AND SAVING OF FELLOW CONTESTANT KYOKA JIROU, YOU HAVE BEEN REWARDED A TOTAL OF 97 HERO POINTS! RESULTING IN YOU BREAKING MY PERSONAL RECORD AT 137 TOTAL POINTS BY 67 POINTS!"

Jirou sits there looking at Flynn shocked,
"YOU BROKE ALL MIGHTS RECORD!?!?" She starts buts silenced by Flynn kissing her on the lips.
"YOU HAVE BEEN PLACED IN CLASS 1-A AND HAVE SET A NEW HEIGHT FOR FUTURE GENERATIONS TO REACH FOR! I AM HONORED TO SAY THAT YOU ARE ACCEPTED INTO U.A'S HERO COURSE! HOPEFULLY I'LL LIVE TO SEE YOU BECOME THE NEW NUMBER ONE HERO, NOT JUST IN JAPAN, BUT THE WORLD! WELCOME TO YOUR HERO ACADEMIA!" All Might shouts and bows like he's in front of royalty. The hologram shuts off.
Jirou sits there, stunned at the fact that she's now dating someone so amazing that they have the potential to be number 1 of the world.
"Y-you just got a lot more amazing.. Flynn.. I'll understand if you want to leave me for someone better.. more worthy of yo-" She gets cut off by Flynn cupping her cheeks.
"Hey. Knock that off. I won't ever leave you. I won't ever cheat. I will not intentionally hurt you. Ever. I love you." Flynn says sternly.
Jirou can only hug him and cry in his arms.

A week later

Flynn and Jirou had received their uniforms and tried them on. Jirou was a bit.. uncomfortable being in a skirt, Flynn had thought it was cute. Flynn's, on the other hand, was a bit small, not skin-tight, but enough to highlight his figure. They were both walking into U.A's gates together. They had little trouble finding 1-A.
"Wow, that is a big door." Jirou says, admiring the nearly 5 meter tall door.
Flynn grabs her hand and squeezes slightly, smiling at her. They both walk into the class together, and Jirou immediately freezes at what, no, who she sees.
"GET YOUR FEET OFF THIS DESK! YOU'RE DISRESPECTING THOSE WHO SAT AT THIS DESK BEFORE YOU!" The blue haired man with glasses yells and a spiky blonde haired man with an arrogant expression on his face.
"Haah~? Don't tell me what to do four eyes. Did your old school put a stick up your ass or were you born with it?" The blonde shoots back but notices Jirou standing with Flynn, but he seems to completely disregard Flynn. The blonde gets an enraged expression on his face.
"I THOUGHT I TOLD YOU NOT TO FUCKING APPLY WEIRD EARS!" He screams at Jirou, getting out of his seat and stomping over, screaming more profanities at Jirou, Flynn steps in front of Jirou to both stop the angry blonde and protect Jirou.
"If you know what's best for you.. you'll shut. the. fuck. up." Flynn looks at the blonde with an emotionless expression, but his eyes seem to burn a hole right through the blondes soul.
The blonde gets a little scared but doesn't show it.
"Who the fuck are you? This is business between me and her. So stay the fuck out of it!" He says.
"Oh? Well she's my fucking girlfriend, so I'd say it's my fucking business as well." Flynn says, getting a little angry.
"B-bakugo.." Jirou says in fear after snapping out of her initial shock.
"DONT FUCKING SPEAK TO ME YOU USELESS BIT-" Bakugo was about to launch an explosion at her, who flinched hard, but Flynn grabs his face and slams him into the floor.
"You must have a real death wish.. attacking her like that.." Flynn says, staring at him.
"Don't attack her again.. Do you understand?" Flynn asks him.
"F-fuck you.." Bakugo responds.

Flynn slams his head into the floor a little,
"I SAID, DO. YOU. UNDERSTAND." Flynn says, this time letting out a bit of bloodlust and killing intent.
Bakugo, who was now about to piss himself, nods as best he can. Flynn releases him, and Bakugo rushes to his seat, not even bothering to dust his clothes off.
"Are you okay, Kyo?" Flynn kneels to her heighth and puts his hands on her shoulders.
Jirou does her best to hold it together and nods hesitantly. Flynn knows something is wrong but decides to ask her about it later.
"Teach, you can come out from behind your desk now." Flynn says towards Aizawa.
<He noticed me?> Aizawa thinks.
Everyone in there looks at him in confusion.
"Umm, the teacher isn't in here yet, dude." A guy with unnaturally red spiky hair says.
"He's talking about me dipshit." Aizawa says, rising from the ground. "I'm Shouta Aizawa, your homeroom teacher for the next three years..."
"You guys can introduce yourselves later.. for now.. head to the locker rooms and put these on.." Aizawa pulls out a bunch of blue and white P.E. uniforms from his sleeping bag. "We're going to have a quirk assessment test.."
A petite brunette girl with a forever blush on her cheeks pipes up,
"But sir! What about orientation!" She asks.
"You guys are here to be heroes.. we don't have time for useless ceremonies.."

In the guys' locker rooms

Flynn had just taken off his uniforms button-up shirt, revealing his massive cut muscles and many scars.
"Whoa dude! You're absolutely ripped! What type of training do you do?" The red-haired boy asks.
"...Hellish training..." Flynn answers vaguely.
"Hey guys!" A purple haired midget with balls in his hair says, "Look what our upperclassmen have graced us with!" He uncovered a peephole that everyone assumed led to the girls' side.
"THAT'S NOT VERY HERO LIKE!" The blue haired guy yells.
"So unmanly dude.." The red-haired guy states.
Flynn only stares at the midget like, [Yeah, I fucking hope you do it dude].
The midget is drooling and saying a whole bunch of disgusting things as he tries to look inside the peephole. One of Jirous earphone jacks suddenly stabbed him in the ear, and he yelled in pain. After a little bit, he said,

"Of course, the ugliest girl in the class wou-" He was slammed hard into the locker before he could finish.
"I.. fucking.. DARE you to finish that.." Flynn says threateningly, holding him tightly by the neck.
"I-it's t-true.. Y-you could p-pull so much b-better tha-" Mineta was thrown into the opposite locker and was instantly knocked out. Flynn, now fumming with anger and rage, finishes getting dressed, not caring that the shirt is about to rip its so tight. He storms out of the locker room and towards the training field. Jirou was tearing up at the comments the midget had made, the girls noticing, and asking her what was wrong. Jirou said that the guy with purple hair was about to peek on them when she stabbed him in the eye and that he proceeded to say she was the ugliest, then that Flynn had slammed him into the locker and threatened him. Only for the midget to say something that hurt her extremely bad and the sound she heard that she assumed was Flynn slamming him into another locker, knocking him out and leaving. The girls tried to comfort her, but she already got dressed and left.

A few minutes later, everyone had arrived at the field, the girls blushing at the tight shirt on Flynn.
"Alright, I'm gonna ignore that the midget is gone. Will first place in the physical portion come up.." Aizawa asks.
Bakugo started to walk up,
"Not you dumbass.. him.." Aizawa points at Flynn, who was still pissed from earlier. Flynn walks up, and Aizawa throws him a ball with a tracker in it.
"What was your farthest throw in high school.. oh wait.. never mind, I remembered you were homeschooled.. Just throw the ball as far as you can with your quirk.. anything goes as long as you stay in the circle.." Aizawa orders.
Flynn nods and walks to the circle. Once inside, he wastes no time and transfers his anger into power, a red aura coming off his body. He reals his arm back and yells loudly as he throws the ball. The throw was so powerful that the sound barrier was broken multiple times, and air pressures knocked some of the class over.  About 10 seconds pass, and Aizawa shows the class his tracker, which showed an infinity symbol. The entire class becomes shocked.

(I'm too lazy to go through everything, so I'm just gonna go to Flynns scores on everything I can remember.)

Ball throw: Infinite, tied for 1st place.
50 meter dash: 0.02 seconds, 1st place
Grip test, broke machine, 1st place
Side to side jumps: Robot couldn't keep up, 1st place
Standing long jump: Cleared, place not specified.
Distance run: Finished in 5 seconds, 1st place
Seated toe touch: Full flexibility, 1st place
Sit-ups: No contest, 1st place

Aizawa shows the class the results, the results being relatively the same, except Flynn is in 1st, and Jirou is in 15th. Bakugo raged at the fact he wasn't in first but remembered what happened in class and stopped himself from lashing out.

The rest of the day was boring and uneventful. It was now the end of the day. Flynn and Jirou are about to head to their beds.
"Y'know Kyo, you can sleep with me if you want.." Flynn tells her.
She blushes hard, "Y-you sure?"
"Absolutely positive," Flynn replies.
Jirou blushes at seeing Flynns undressed body, her eyes wandering down to the largish bulge in his boxers.. She blushes harder, thinking that Flynn's hard.
"Whoa~! Calm down there, babe, not yet." Flynn teases her while smirking.
Jirou quickly becomes flustered,
"S-shut up.."
Her and Flynn climb into bed, both being slightly embarrassed, but Flynn wraps his arms around her and pulls her close, embracing her. Kyoka Jirou blushes hard but quickly relaxes, feeling safer than she has in years. She snuggles into his chest and falls asleep quickly. Flynn followed her into sleep not long after.
