Izuku Midoriya (Quirk: One For All) and Mei Hatsume (Quirk: Zoom), U.A. High School First Year students. The first teenager was in the Hero Course, Class 1-A. The second teenager was in the Support Course, Class 1-H.

They have been best friends ever since they met at the age of four, the day little Izuku was saved by little Mei and her father when the boy was found on the ground of the playground beaten up. He tried to protect a neighborhood kid from two bullies and his former childhood friend.

Izuku two weeks later met the girl again when he ventured to the playground. On that day he started hanging out with the cute daughter of the Hatsume family more, and less with Bakugo until age five he only saw him as a classmate and nothing else.

Izuku and Mei were glued together, often hanging out at one another's house. Mei was fascinated with Izuku's brilliance when it came to his analysis on the pro heroes of Japan. Izuku was amazed with Mei's creations and gadgets, always inventing cool things even though some stuff tend to explode. And the fact she did not care if he was quirkless made him more happy.

Until a certain day in Izuku's life changed and he was bestowed the power of One For All, Izuku and Mei were already happy together, content to live the rest of their lives together, being the best they can be as inventors in the Support Business and as future parents raising a family in their adult lives.

But at age eleven, Izuku and Mei one day discovered that other worlds and universes existed. And they met a man who had the coveted technology to travel freely to all these different universes. The views they once had completely changed and they started to change due to having experienced seeing other worlds; the two did not tell anyone in their world since it would be really farfetched. Unbelievable. Still, pretty cool to learn new shit.

Even with altered destinies, they're still together as boyfriend and girlfriend attending U.A.

Fun Fact: During the U.A. Sports Festival, Mei Hatsume had publicly declared she was Izuku Midoriya's number one supporter. She also had developed Izuku's Pro Hero Deku costume data two months before the U.A. Entrance Exams.

Today, the two teens were all alone in the apartment and currently in the living room. The boy's mom was at work. Izuku was lying on the sofa which had been covered by a blanket and Mei was on top him.

"That was so good, Izuku," said Mei, caressing her boyfriend's nude chest. She loved the lean muscle her boyfriend developed since fifth grade.

"So good, Mei," Izuku whispers sweetly, his hands caressing her lower back to her sweet rear end. Both lovers start passionately kissing again.

A day had passed since the I-Expo incident, and both of them and Izuku's friends whom gotten involved had survived the dangerous incident. Many innocent people were harmed from this incident. David Shield, a wounded victim, was going to make a full recovery. This however canceled the rest of the expo. The main villain, despite having been fully empowered by the device David Shield had built (before it was confiscated due to dangerous risks it possessed), still got his ass handed to him by the team-up of Izuku and All Might. But before the villain attack, Izuku and Mei had very much enjoyed visiting I-Island three days before the expo and finally meeting their online friend of a full year Melissa Shield. For those who are wondering how they got there: Melissa invited them both, and their ride to the island's airport was via carship (to save money on flying).

"Izu-kun... mmm..."

Hm...

Teenagers...

"My sweet beautiful inventor," Izuku whispers lovingly.

The two locked lips, sharing another romantic kiss. It don't matter what universe you live in, teens in love will enjoy the world of romance.

"We better make sure to clean the blanket we threw on the sofa," said Izuku after the kiss ends.

Mei smiled softly.

"Glad we still had one more contraceptive vial."

The greenette nods. "Remind me to get more from the wizarding world."

The couple share another kiss before getting off the sofa. Izuku takes the stained blanket to the washer, and once its running he returns to the living room. He caught his pants thrown to him by Mei.

"If only your admittedly hot mom wasn't going to be home in an hour," said Mei, disappointed that their fun time had to end. She is slipping her shirt back on.

"We've been naked since eight this morning the minute mom went to work," Izuku told his girlfriend, grabbing his shirt off the table lamp (surprised it didn't fall when it was tossed aside) and putting it on followed by his pants.

He then adds, "Admittedly hot mom? Mei, I am being truthful and honest when I say mom can still be a MILF."

"Would you?"

"I'm sure in other alternate realities mom and I are having incestuous relations, but I can't see myself breaking that boundary in this dimension even if I enjoy the trope in my fanfiction and manga... thanks mostly to our friends from NV-21."

Mei took her time teasing Izuku with putting on her customed workshop pants with the wide satchel-style pockets on both thighs. She even gave a little shake of her cute ass.

"I am surprised your neighbors didn't bitch considering how loud we got a couple times today."

Izuku shrugs. "Or my neighbors are pervs and listened in for their audio spank bank."

Mei stuck her tongue out at her boyfriend. "If anyone listens to us getting it on, its our close friends, got it?"

Izuku finished washing his hands and was taking out a bag of pizza rolls and fries to deep fry once the oil pot on the stove is heated at the proper temperature. Mei meanwhile opened all the windows to freshen the air in the room.

"Hungry, honey?"

"Fuck yeah, sweetie. Also thirsty as hell."

She dug into the fridge and takes out a 32oz bottle of melon Gatorade, and in one go drank it all. She tossed another bottle of the sports drink to Izuku. He too drank in a single go. Mei snatches the tossed bottle from Izuku and she puts them in the plastics recycle bin.

A green portal opens up and out steps a periwinkle blue-haired man in spiky locks, unibrow, with a balding spot at the back of his head. He wore brown pants, shoes, light blue shirt, white lab coat.

The old man sniffed the air.

"What the fuck? Smells like hardcore sex in here," he declares, speaking in perfect Japanese.

The teens blushed.

"So, Rick? We're teenagers in an empty apartment while my mom's at work for another hour before she comes home."

"It'll take more than an hour to get rid of the evidence of your youthful teenage hijinks," Rick declared.

The man, Rick Sanchez, typed on his watch and sprays a gentle fading pink mist into the air in the living room.

"Mmm... passionfruit and vanilla," Mei moaned in delight of the now fresh scent that eliminated all evidence of sexual musk.

Izuku stares at the man who is from another universe.

"Thank you, Rick."

"You're welcome, kid. So, you two doing anything tomorrow?" Rick asks.

"No," the kids answer.

"Want to go to the esper version of Japan? I got something there to deal with and thought you two could tag along, see your friends."

They smiled happily. They can hang out with Misaka and her friends while Rick took care of his business.

"What time we leave tomorrow?" the two inquired, grinning.

Mei then nudges her boyfriend with her elbow.

"Oh! Rick, if you have the time, could you go to that shop in New York's wizarding world for me, please, and buy another pack of the... um..."

Rick held a hand up, silencing Izuku.

"No need to sugarcoat. At least you're practicing safe sex. Most teens don't in my universe. If they did Mtv wouldn't have any Teen Mom to broadcast for closet sex offenders to enjoy."

"I know. We've seen all those spinoffs of Mtv's Teen Mom, including that failfest that was Teen Mom Jr. High," Izuku told him off.

Mei cracked up. "Whoever thought that was a good idea... what a fucking moron. One episode before it was taken off-air."

"Yeah. Just imagine how many pedophiles raged on social media and getting caught for loving that shit show," Izuku says with a laugh.

Izuku adds the fries to the hot oil carefully. Rick tells the kids he'll pick them up at seven in the morning at the neighborhood playground before leaving this world to return home via portal.

Quiet in the kitchen.

"Hey, sweetie?"

Izuku smiles. "Yes, dear?"

Mei hugs him from behind.

"Think it would be possible if we can also get to visit The World one day? I do miss Shugo and Rena."

Izuku turns around to give her a loving kiss.

"You wanna partner swap, do you, honey?" he teases. "We just need to find the time to get away, and I have that summer training camp in a few days. If mom wasn't coming home in an hour, I'd grab the Sling Bracelet and off we go."

Ever since the Morty Gets a Dragon episode, Rick kept the magic wand from the dead dumbass called the Dragon Taming Wizard and manages to scientifically reverse-engineer it into a magic/science-fused compact portal-making bracelet (auto-adjusts to a perfect fit around the wrist) based off (or in Rick's case ripped off) the Sling Ring used by Doctor Strange. It basically looks like the Sling Ring but equipped to your wrist. Obtained one day after Izuku had turned fourteen.

Mei smirks. "I still remember when we met Shugo and Rena last year. And when we were twelve getting the chance exploring that other alternative version of a quirkless Earth."

Izuku nodded.

"LMNH-12. Spending the day with Daisuke Kamiya, Yoichi Kujo, Soramaru Kisaragi and his year younger brother Chuntaro Kisaragi, Sasuke Hanayuki, Sakura Morikawa, Izuko Midoriya and her five years younger sister Eri Midoriya and their official leader of the Ai Mahou Shinobi Team, Yuri Shishido."

Who knew there was an after school club called The Lovers Club (its not what you think, you perverts) at the middle school in that universe's Hikone, Japan? And that the nine kids were secretly ninja heroes who fight magical demons called Ayakashi. The heroes were aware of magic and spirits, and were aware of other worlds existing (albeit they are spirit worlds). But dear sweet goddess, Yuri reminded Izuku so much of Koneko, now that he recalls the cute white-haired girl. Plus it was a shock that Izuko was actually him but born female.

"It got as spicy as Trish Una's Stand, when at Yuri's home all of us for two hours were romantically connected together. Romcoms and action movie flicks being enjoyed."

The pinkette was amused with the memories of that day, even when they all at one point watched Izuku and Izuko kiss and make out to answer a curious question: was it incest if you kiss your gender counterpart? The answer was never discovered as they, including Izuko's little sister Eri, found it fun to watch. They put an end to it when the twins began to drift hands toward naughty places.

Then Mei starts thinking on the young men who Trish Una, someone Izuku brought up in his sentence earlier, was in company of.

"I wonder how Giorno Giovanna and the rest are doing since that encounter when we were thirteen?"

"We almost got killed that day, Mei-chan. But Gio was the most level-headed, thankfully, seeing we weren't the enemies that were hunting them down."

Izuku still remembered the enemy Stand attack that they unfortunately wandered into while in Sardinia and what had happened to him. Gio's Stand, Gold Experience, regrew his lost hand though. Thank Rick those aviators they wore picked up the forms of the special projected psionics to avoid deaths, but for a brief time Bruno Bucciarati thought them mafia members. To think that an Italian version of Rick Sanchez and Morty Smith even existed in that universe.

Mei suddenly rattles off, in Italian, "Le patatine stanno iniziando a bruciare (The fries are starting to burn)." Then she points to the stove.

"Cazzo!" Izuku cursed in the same language and tended to the slightly overcooked fries.

The pinkette just smiled and takes a seat at the table, taking her phone out.

One hour later, the door unlocks and in steps Inko Midoriya. Seven o'clock, on the dot.

"I'm home!" Inko calls out, as she closes the door and twists the above latch, locking it.

Inko was a beautiful woman, and through the fifteen years of being a loving mother to an amazing son, those years have been good to her. Slim healthy body, nice curvy hips, a fairly big and modest bust, dem legs.

Age, after all, is but a number.

Izuku however gets annoyed from time to time when the other boys from the neighborhood like to ogle his mother. Like this one particular incident when he was twelve years old and some bastard from school wouldn't stop talking very dirty about the sexual things he'd do to his mother. The one week of detention was really worth it. The kid never talked dirty about his mom ever again after the beat down.

"Welcome home, mom," Izuku greeted his mom from the sofa.

Mei smiles. "Hi, mom."

Inko smiles brightly to her darling son and her one day future daughter-in-law.

"I hope you two didn't stay indoors all day," she says, entering her bedroom.

The two shared secretive smiles.

When Inko enters the living room, now dressed in a pair of fitting sweat pants and a chiffon lemon yellow t-shirt, she gave both kids a hug and a kiss on each head.

"We did some exploring today. We returned back about an hour before you would be home," said Mei.

It was a harmless white lie.

"Mei is staying for dinner, mom," said Izuku.

"You told your parents, Mei?"

She answers, "Yes."

Izuku and Mei cuddle up and continues watching the movie playing on TV.

"Izuku, sweetheart?" Inko called from the kitchen ten minutes later.

"Yeah, mom?"

Inko walked over and sets down a box of twelve count condoms on the coffee table. The two teens froze.

"I found an empty box in your room yesterday while taking care of the laundry so I bought you more." And she returns to the kitchen. "I know that you are growing up, both of you, and a part of me wishes you were still my little precious treasures. But I am glad that you would practice safely."

Inko smiled with a light blush.

"Just don't give me grandkids while your both still in high school," she says and starts prepping for tonight's dinner.

Izuku and Mei look at each other.

"But once you both graduate from high school, then you can fuck with no condoms all you want until you two bless me with a grandchild or two," Inko happily finishes her train of thought.

The blushing teens sweat drop.


[Cue "Rick & Morty" Theme]

Random things float about: Hourglass. A bent gold metal baseball bat. 2+2=4. Flying eyeball inside palm of hand shooting lasers. A pink pile of poop with a cheerful smile stuck on the end of a wooden stick. We focus on an alien planet with twin rings at an X cross, descending onto the planet's surface. Running across a barren wasteland is Rick, Morty, Izuku and Mei being chased by aliens. When Rick pulls out his portal gun, Izuku scoops his girlfriend into his arms whilst initiating One For All: Full Cowling. Rick shoots a portal into existence. Izuku keeps Mei firmly in his embrace as he boost jumps them into the portal quickly followed by Rick baseball sliding in. Morty tripped and fell as the portal closed and vanished. The teen gets up just as green round pudgy monsters bounce up and dive at him.

Rick Sanchez and Yukari Yakumo are competing in PvP battles on Pocket Mortys. Outside Yukari's home in Gensokyo, Morty is getting a crash course learning about Spell Cards and Danmaku by dodging a green wave of star-shaped bullets from Izuku armed with Marisa Kirisame's Hakkero and skateboard-riding a wizarding broom in the air.

Neptune, Izuku, Eri, Mei and Nepgear are playing Super Smash Bros. Ultimate and are in their sleepwear. Neptune and the cute loli Eri are wearing matching short purple nighties with black spaghetti straps and lavender panties. Izuku only has on green boxer shorts since Mei, in her lingerie pink panties, was wearing Izuku's t-shirt. Nepgear has on a lavender nightshirt that reached down to her thighs. The characters fighting on the TV are Cloud Strife (Neptune), Dark Samus (Izuku), Ren Amamiya - "Joker" (Eri), Rockman (Mei) and Lady Palutina (Nepgear). The others are smiling and having fun because of Eri's cheerfulness.

Izuku and Morty are in the back of a classic black Rolls Royce firing laser guns at the Plutonian mob cars chasing them. Rick does what he can to dodge the mob while speeding through heavy city traffic. After one incredible undescribably insane tricked out car maneuver that makes Vin Diesel so hard jelly, Jerry (riding shotgun) vomits all over the dashboard.

Springtrap screeched whilst jumping out ready to kill his next victim but Izuku and Mei punched the yellow animatronic rabbit, before pulling out crowbars and start viciously wailing on the poor bastard, whose now curled up crying like a little bitch. A group of gamers consisting of Iron Man (VanossGaming), Superman (Markiplier), the Plague Doctor from Assassins Creed (SeaNanners), Jake from Adventure Time (LuiCaliber), Captain America (H2ODelirious), John Cena (Miniladd), Zoidberg (Daithedenogla) and a seven foot tall super bodybuilding muscular tan Japanese man with thick cut super hard cum gutter abs wearing small blue speedos but having the tiny head of the ground Pokemon Diglett (Wildkat) stare in shock while keeping a short distance away. Morty was frightened and hiding behind Rick who watched the violent beat down while eating a slice of pizza from a box with a bored look on his face.

Izuku Midoriya and Mei Hatsume have been turned back into a four year old shota and loli thanks to a de-aging potion. They are being taken care of in the private outdoor hot springs bathhouse by Rias Gremory, her female peerage members, and Sona Sitri and her female peerage members. Izuku is sitting in Sona's lap, happily leaning against her breasts with a smile while Sona is holding him. Mei sits in Rias' lap, leaning against her breasts with a blissful smile as Rias hugs the cutie. Marshmallow heaven.

Dark sea of clouds, a ruined landscape, and nightmares that dominate this place. Rick is flying the carship as fast he can while dodging broken buildings and pillars of towering obelisk. Morty, Izuku, Summer and Mei are freaking out. Why? Cthulu was chasing after them, fast on their heels and barreling through whatever stood in its path. But why Summer is holding its baby offspring is a mystery. Still, Cthulu wants its baby back, as it unleashes the haunting cry that drives all who are unlucky to hear beyond the realm of insanity, and beyond the black abyss its circular razor rows of sharp teeth are bared in unholy terror.
