Smooth as Skippy

“Speech” Thoughts

 

Hope you like it ;;

 

The letter from UA was finally here. It had arrived in the mail last night and Kacchan and Izuku had determined that they should wait until Mistuki would return in the morning. Izuku rolled out of bed, hitting the floor with a loud thump. Getting up and rubbing his eyes, Izuku walked into the bathroom, opened the medicine cabinet and popped his pill into his mouth.

 

After doing a few stretches, Izuku walked over to Kacchan’s door, knocking on it. Instantly the door was opened and Izuku saw Kacchan already ready for the morning’s workout session.

 

Izuku looked down at his pajamas and shrugged. He was too tired to care what he looked like right now. The duo did a light jog around their park a few times before coming back and showering. Now fully awake, Izuku was jumping on Kacchan, excited for the results.

 

“Fucking calm down! It’s not that big of a fucking deal!” Kacchan yelled, tired of his friend's antics. “You were so fucking tired this morning and now look at you! Did you stay up late texting your fucking girlfriend?!?!”

 

Izuku froze. Kacchan was right, Izuku had stayed up until one o’clock texting Ochaco. They had become really good friends in the past week. Izuku just shifted his hold on Kacchan, turning it into a wrestling hold and trapping Kacchan’s arms and legs.

 

“Da Fuck! Get off me!” Katsuki yelled, trying to elbow his friend.

 

Izuku eventually relented, mostly after Katsuki threatened to stop cooking for him, and by then Mitsuki was home and they were prepared to open the letters.

 

“YOUNG MIDORIYA!!!” The projection yelled. Instantly Izuku snapped his hands over his ears, and covered his eyes. He felt the memory start to surface, and started counting backwards from one thousand by sevens. Once he got down to six, Izuku opened his eyes. The memory had retreated to the back of his mind. It was always there, but it was far enough back that he didn’t always see it vividly.

 

The projection was gone, and Mitsuki was by his side, rubbing his back. “I have to get over that.”

 

“No you don’t Izuku, you saw something no teen should see, so don’t say you need to get over it.” Mitsuki said, still rubbing her hand over his back.

 

Izuku waved the hand away and stood up. “Did Kacchan take the letters into his room?” Mitsuki nodded.

 

“The damn brat took them into his room and is finishing up both of them, he said he’ll tell you what it says.”

 

As if on cue, Katsuki screamed out of his room, “We both got in! I placed first, you second! Apparently there are dorms we are gonna fucking live in!”

 

“WATCH YOUR FUCKING LANGUAGE!!!” Mitsuki shouted back.

 

“SHUT IT OLD HAG!” Kacchan replies, but he did seize cursing as much. Izuku smiled, and hugged his Auntie.

 

“I never really thanked you for taking me in Auntie. So I’m going to say it right now. Thanks.” Izuku mumbles.

 

Mitsuki laughed, patting the greenette on the head, “Don’t worry about it! Inko woulda haunted me if I didn’t take you in, and you already felt like one of mine since you always came over.”

 

Izuku smiled into the older woman's chest, before releasing the hug and running up the stairs. He knocked on Kacchan’s door and he opened the door.

 

The little green child jumped onto his friend's body, hugging him tightly, tears streaming down his cheeks. “W-we got in! We can be heroes!”

 

Katsuki smiled, “Fuck yeah we can.” They hugged like that for a while, until Katsuki got impatient and nearly through Izuku out a window. The rest of the day was spent in happiness, with beef katsudon for lunch, and Death Curry for dinner.

 

========

It was the first day of school, and Izuku was waiting at the bus stop for a certain bubbly girl. He had already told Kacchan of his plans so his friend was already at school. Tapping his foot nervously, Izuku passed the time by Pushing a marble up and catching it. After what felt like hours, but was in reality two minutes, the bus screeched to a stop in front of him.

 

“Zu! Over here!” A familiar voice called. Izuku smiled and walked over to the jumping hand. He wrapped his arms around the girl and squeezed her tightly. He had long since gotten over his fear of talking to her.

 

Uraraka laughed and hugged him back. “Glad to see you missed me!”

 

“Course I missed you, you’re one of my only friends!” Izuku muttered into her shoulder. Uraraka laughed and patted his back, making sure to have one finger lifted. 

 

“W-well let's get going to school! Don’t want to be late for the first day.” Uraraka grabbed his hand and they began walking down the path chatting quietly.

 

Awww, what a cute couple. Deku thought sarcastically. Izuku’s face flushed red and he realized he forgot his pill. For someone who remembers everything he sees he sure does forget about taking a pill a lot.

 

“You alright Zu?” Uraraka asked, concerned.

 

“Y-yeah, I’m fine.” Izuku mumbles, even more embarrassed than he had been before.

 

Oh now I really want to mess with her. Deku thought.

 

Izuku growled back, Don’t. Even. Think. About. It.  Deku just chuckled in his mind.

 

“Something wrong? You tensed up all of the sudden Zu.” Uraraka said, visible concern on her face. Izuku just smiled back and continued the conversation they had been having. Once they reached school, Izuku released Uraraka’s hand and opened the door for her, where they began the long walk to Class 1A.

 

When they finally arrived it was chaos. “Please take your feet off of the desk! It is disrespectful to the school and the creators of this fine instrument of learning!” Some glasses kid yelled.

 

Bitch, thought Deku. 

 

Language, replied Izuku.

 

“I’LL PUT MY FEET WHEREVER THE FUCK I WANT!!!” Kacchan screamed back.

 

“Language!” Called Izuku again. Kacchan just scoffed and rolled his eyes once he saw the greenette. The glasses kid turned around and ran up to him.

 

“I apologize for my rudeness at the entrance exam! It was uncalled for since you realized the true reason behind the test! My name is Iida Tenya!!” The boy, Iida, cries out.

 

Izuku just hid behind Uraraka, not liking meeting the over enthusiastic kid that had approached him. Uraraka laughed and introduced the duo. Using her as a shield, Izuku made his way to his desk and sat down, with his friends in front of him and to his side.

 

Pussy, Deku said, laughing at Izuku’s ridiculous timidity. Deku wanted to yell at the class, but Izuku’s overwhelming nervousness overpowered him.

 

Izuku just shrunk into the desk, face beet red. Suddenly, a tired voice called out, “If you’re here to make friends then get out. We are going to the field so put these on.”

 

A yellow caterpillar held out a pair of gym clothes, and slowly emerged from its cocoon.

 

Izuku accidentally Pushed on everything in the room. Pencils and backpacks went flying, a few of the lighter students fell out of their chairs. Izuku squealed in delight. Squealed. A fifteen year old boy squealed. Both personalities were excited once they saw that scarf.

 

“ERASERHEAD!!!” Katsuki whirled around at the excited shriek, he had been pushed to the edge of his seat by Izuku’s Push, and he bopped him on the head. 

 

“Calm down Zu, it’s just our shitty teacher.”

 

Deku gasped loudly, shooting Kacchan a wounded look, “How can you fucking say that?!! Have you seen the shit we made? He is the best fucking pro hero to ever live!!”

 

Deku heard a slight gasp from beside him, probably Ochaco after hearing him cursing, but that was Izuku’s problem not Deku’s. “Just shut up and get ready.” Eraserhead said. “And call me Aizawa or Sensei.”

 

“Yes sir.” Deku said, standing up quickly and bowing. He could feel Izuku’s own excitement match his own. Everyone picked up their stuff and followed the over enthusiastic greenette out the door. He changed into his PE outfit, and ran outside, Pushing anything not tied down away by accident.

 

They usually had a small Push on everything around them, not enough to actually move anything, but it gave them a very good sense of where everything was, because spatial awareness was a very important thing with his quirk. When he got excited he usually flared his quirk on accident.

 

Deku was the first to reach the field, changing in a few minutes because of excitement. When he got there no one else was present so he began to stretch a bit. After finishing up his series of stretches, Ochaco and Kacchan as well as a few others had gotten ready.

 

Trotting over to Ochaco, Deku grinned madly. “Wow! I’ve never heard you cuss before Zu!” She said, evidently surprised.

 

Deku just smiled, “You still haven’t.” Ochaco cocked her head in confusion. Poking her cheek, Deku smiled at how cute she looked.

 

So you do like her! Izuku accused, laughing at Deku’s adoration for the girl. He just grumbled and didn’t respond.

 

“Oi! Nerd! You forgot your fucking pill! I even reminded you!” Kacchan screamed, smacking Deku on the head.

 

“Pill? What pill?” the bubbly girl asked. 

 

Kacchan growled out, “This fucker takes a pill to stop himself from flipping personalities all the damn time.”

 

“Yeah and we fucking forgot today so here I am!” Deku said, opening his arms in fanfare. He fist bumps Kacchan and turns back to where Eraserhead was standing. 

 

Please don’t be mean. Izuku pleaded, but Deku didn’t say anything, making Izuku even more worried. As the class slowly trickled in, Aizawa got out of his sleeping bag and waited for everyone to quiet down. “It took you fifteen minutes to get ready, by the end of the semester it needs to be down to four.”

 

Deku smiled, he had finished in less than four minutes, and was the only one to do so. Aizawa continued on with his explanation and Deku paid attention with intense interest. The explanation done, he called Kacchan to the circle.

 

“What was your record for the ball throw in middle school?” Aizawa asked.

 

“About sixty seven meters.” Kacchan replied.

 

The scarfed man whipped out a ball and handed it to the explosive teen. “Try it with your quirk.”

 

Kacchan smiled wickedly, and grabbed the ball from his hand. He walked into the circle and cocked his arm back. “DIIIIIIIEE!!!!” He screamed, rocketing the ball off with an explosion. Ochaco was taken aback, and cocked her head in surprise.

 

“Die? That’s what he yelled?”

 

“Fuck yeah it is!” Deku said, smiling evilly.

 

Ochaco paused for a second. “I don’t know whether I like you or innocent Zu more.”

 

“Definitely innocent, I’m a fucking maniac.” Deku said with a smile. “Don’t worry, I won’t interrupt your lovey dovey time where you stare into each other’s eyes.” He felt Izuku burn with embarrassment and saw Ochaco’s face burn bright red.

 

Turning back to their teacher, the duo saw the distance displayed on the screen. Seven hundred sixty eight meters. An impressive record, one Deku didn't think he could beat. Everyone gasped in shock.

 

Deku gave a silent fist bump to Kacchan as he listened in on everyone’s conversation.

 

“Wow! That’s amazing!”

 

“We can use our quirks?”

 

“This is going to be fun!”

 

At the last comment Aizawa frowned, and turned back to the class. “Fun? This is going to be fun? Let’s see how fun it is if whoever gets the worst score gets expelled.” Deku didn’t react, nor Kacchan, but everyone else flipped out at the prospect.

 

“Just be the best and you don’t have a damn thing to worry about.” Kacchan said and walked to the next test. The tests went by fairly quickly, with Deku pulling ahead of almost everyone with ease. He just flew across the floor for the long jump and high jump. For the grip test he pushed on the two sides, forcing them together until it flung him backwards. For the running, he pushed off the building and the floor to speed across the ground, inches above the rest. As he had suspected, he didn’t quite reach Katsuki’s record for the softball throw, but was fairly close. 

 

After everything was said and done, with Deku placing a measly fourth, Aizawa dismissed them for the day, declaring the expulsion threat a ‘logical ruse,’ (Deku and Izuku knew better, they had stalked him for the last year), and everyone broke to get to their rooms. Their stuff had been delivered to the rooms during class, so that they could spend one last morning with their families.

 

Deku took a quick shower and began unpacking the few things he brought with him. He had his Eraserhead things he made, as well as a sketchbook if he needed it. He had two, one to draw heroes, and the other to help him stay sane. If he drew certain memories it helped them place it into the back of his mind. He had a little desk and his bed, as well as a couple pairs of clothes.

 

He threw on some sweats and a tank top that said, ‘Deep Dope,’ which was his favorite band, they weren’t well known but they had some really good songs. Izuku had bought a cheap guitar despite Deku’s griping, and it was propped against the wall. They may have a perfect memory, which let them draw fairly well, but it didn’t help them develop a talent as difficult as playing an instrument.

 

Once everything was unpacked, Izuku picked up the guitar, sitting on his bed. Placing it on his lap, he remembered the Deep Dope song that he really liked, it had a pleasant beat and started off fairly slow. He started off, messing up right when the rhythm started to pick up. Sighing, Izuku put it down and leaned it against the wall. He heard a knock on the door and walked over, yanking it open. 

 

One of his classmates, Jiro, was panting outside of his room. “W-was that D-Deep Dope?” she gasped out, clutching her chest.

 

Izuku just nodded slowly. Well it seems like she’s a fan. Maybe she can take that damn guitar. Deku thought. Izuku suppresses the urge to roll his eyes, and chooses to nod his head to his classmate's question. “It’s one of my favorite bands.”

 

Jiro’s mouth hung open, and stared at him. “I-is there something on my face?” Izuku said, trying to wipe whatever she was staring at off. 

 

Smooth as Skippy Zu, Deku said, sarcasm dripping in his voice. Izuku again, suppressed the urge to roll his eyes.

 

“It’s just… that’s my dad's band!” Jiro said, finally catching her breath. Izuku did a double take, staring at her with his jaw open.

 

“Really!??! Wow… that’s amazing!” Izuku began jumping up and down. For the next half hour they talked about their favorite and least favorite songs, Jiro even helped him out a bit with the guitar. By the time she had finished teaching him how to play, they heard noises coming from the common room. 

 

Together they walked down to the ground floor, seeing everyone, except for the kid with two different hair colors, gathered in a circle. Even Kacchan was dragged in by some red head spouting about manliness. Izuku gave him a small wave, before sitting down next to Ochaco and Jiro.

 

“Hey you two!! What were you doing up there by yourselves?” Ochaco asked, genuinely curious. 

 

Izuku smiled and said, “We were talking about that band I told you about, Deep Dope!” Ochaco beamed, and looked at Jiro.

 

“He would always text me about some song, but I had no idea what he meant! It’s nice to know he can talk to someone about it!” the bubbly girl said with a large smile. Izuku returned the smile and turned his attention to the conversation among the other members of the class.

 

“LET'S DO A KING OF THE ROOM CONTEST!!!” A pink girl screamed, Mina. The invisible girl and Ochaco jumped enthusiastically. Most of the guys begrudgingly accepted, and the few who resisted were pushed aside.

 

It was finally Izuku’s turn, he was the last one on the boys dorm, all the way up at the top back of the class A dorms. He stood in front of his door with his feet planted on the ground, Pulling hard on the floor to anchor himself into place.

 

All the girls had tried to get him out of the way, and they all but begged Ochaco to do something.

 

“Please! Please Uraraka! Do something!” Mina shrieked, holding onto her friend's clothes.

 

“Well… I don’t know…” she mumbled, nervous. Kacchan walked up to her and whispered something Izuku couldn’t hear, but it made him sweat when the other girls nodded their heads vigorously.

 

Ochaco’s face turned red but she walked over to him, and Izuku strengthened his stance, waiting for the inevitable tackle. Instead he felt a slight kiss on his cheek. Instantly, Izuku’s face went redder than Aizawa’s eyes, and he fell into his butt, stopping his Pull on the floor. 

 

Not waiting a moment, the girls rushed into his unlocked room, leaving Izuku to shake himself out of his stupor to rush in behind them.

 

“Wow!!”

 

“Is that Aizawa-sensei?”

 

“Did you draw this picture?”

 

“Is that a sculpture?”

 

Izuku yanked Mina away from his sculpture and moved to block the picture on the wall. He had since colored it in and had it glaring down at everyone, his scarf floating above his head.”

 

“This is seriously impressive Izuku.” Kirishima said, looking up at another drawing of Aizawa stooping on the edge of a building. 

 

“Thanks…” Izuku mumbles embarrassed.

 

“Zu was always a hero fan, you should have seen his reaction when I walked in on him drawing this.” Kacchan said, chuckling at the memory.

 

“Do you play guitar?” Kaminari asked, looking down at said instrument. Izuku just gave a nod and glanced over at Jiro, who seemed to be looking at the guitar as well.

 

“Where are the books? Do you not feel the need to study? That is very unbecoming of a hero student!!” Iida scolded.

 

“I-I already have them memorized.” Izuku squeaked out. “I read them last week.” Everyone stopped their pilfering of his room to stare at him.

 

Bitch, Deku thought. Izuku smiled at that, but only slightly.

 

“You mean…” Yaoyorozu started, looking at him.

 

Izuku just shrunk behind Kacchan, and peeked his head out. “I have a perfect memory. I remember everything I see, it’s kind of like a scrapbook in my mind. As long as I go to the right 'page', I can find any picture.”

 

“He was always a smart ass.” Kacchan said, patting Izuku on the head.

 

Everyone was silent for a moment until Ochaco spoke up. “You have sketchbooks? That’s so cool!” Izuku whipped his head up, hoping that it wasn’t his “Therapy Sketchbook.” It was. Before Izuku could do anything she cracked it open and gasped loudly, hand flying to her mouth..

 

Staring back at her was the dead eyes of Izuku’s mother, her mouth hanging open and blood falling from her head. It wasn’t a finished sketch, it didn’t have the All Might figurine inside of it, but it still set off Izuku.

 

He saw the memory play back again, walking through the house, smelling the blood, seeing the body. Count Zu! Fucking count!! Screamed a familiar voice. 

 

1000… 993… 986… 979… 972… 965… 958… 951… and so on, reaching six before counting all the way back up to 1000. Releasing the final breath, Izuku opened his eyes, seeing his classmates standing outside of the room, and Kacchan by his side. Quietly, he picked up a pencil, opened to a new page and quickly sketched out two hands, one clenched and the other with two broken fingers. Finally, after what felt like ages, he closed the book and smiled.

 

Thanks Deku, you're the best. Izuku thought, smiling. 

 

Don’t mention it, I may be a bitch but I’m still you. It hurts you a lot more than me. Deku replies, a grin evident.

 

Turning back to his concerned classmates, Izuku smiled tiredly, “Like I said, I remember everything.”

 

Ochaco was the first to break the silence, walking forward and hugging Izuku tightly. “I’m so sorry, I didn’t know. I didn’t mean to hurt you!” 

 

“It’s fine.” Izuku replied, melting into the hug.

 

“No it’s not! We shouldn’t have been snooping in your room! You obviously seemed distraught-” Ochaco’s further talking was cut off by Izuku pressing his lips against hers. It was a surprise for both of them, Izuku just did it because it felt right.

 

Fucking finally! I may like her too but I’m not gonna be a bitch about it. Deku thought, obviously grinning at him.

 

Izuku pulled back from the kiss and smiled. “It’s fine Ochaco.” Then they both realized what happened. Ochaco started floating to the ceiling and Izuku Pushed himself out of the balcony window, flying through the air and into the sky beyond. Izuku didn’t look back, too embarrassed to return. Hopefully Kacchan closed his Eraserhead shri- room. His room. Not a shrine. A room.

 

Izuku didn’t realize where he was, he had Pushed off of Shoji, so he didn’t use too much power, instead only going a bit out of the building, ending up very close to another one that looked identical to theirs.

 

The only difference was that instead of a giant ‘A’ on the front of the building, there was a ‘B’. Izuku just shrugged and walked in, curiosity getting the better of him. As soon as he entered the building, the first thing he noticed was that no one was in the common room, and the second was that there was a large amount of fur already covering one of the couches.

 

“Must be one of their quirks, I remember seeing a lion-like person at the entrance exam.” Izuku said, looking at the fur. It was about three inches long, and if his estimations were correct, then this man towered over everyone in his class.

 

What else would it be, a giant dog?? Deku asked sarcastically.

 

“Why do you always insist on being so sarcastic Deku?” Izuku asked, continuing his journey around the common room. He found some glue on the stair well, as well as a slight amount of fungal growth. 

 

It’s in my nature. Blame the quirk not me. Deku thought, smugness radiating off of him.

 

“If I could Push you into the sun I would.” Izuku said, finishing his examination and making his way to the stairs.

 

You love me too much, I do keep you sane. Also, why are you talking aloud right now?

 

“I don’t know, it makes me seem insane, and I’m trying not to think about what just happened.”

 

About what happened, you mean how you just kissed Ochaco? 

 

“Deekuuuu! Please? I won’t take the pill tomorrow if you stop mentioning it today.”

 

Oh, deal. 100%. 

 

“Good, now lets see if we can find anyone.” Izuku said, before hearing a creak of a board behind him. During his last spout with Deku, he had made his way up to the second floor.

 

Whipping around, Izuku saw a red head girl looking at him, followed by some twenty people. 

 

Bro you fucking dead. Deku thought, laughing as Izuku started sweating bullets.
