It had been a few days since Izuku left the apartment. He didn't have preschool since it was currently summer break, and he didn't really want to play with Kacchan anytime soon. So he sat there longingly staring out the window. His mom took notice of his behaviour.

"Izuku sweetie, we're going to the grocery store." They really didn't need groceries but she could tell her son needed to expend some energy.

Izuku whipped his head towards his mom "Ok!" he answered. Finally, something to do.

As they were driving towards the store Izuku spotted something strange in the air. It looked like a little black fuzzball with tiny wings. It was hovering above some strangers head. 'Odd, I wonder what his quirk is.' He thought. They continued driving. As they stopped at a red light Izuku started to notice more. They were tiny, about the size of a raisin. It was easy to miss them unless you were looking for them. They were one or two floating above people's heads. Izuku's eyebrows knitted together in confusion.

"Mommy, do you see the fuzz balls?" he questioned. His mom glanced at Izuku through the mirror for a second.

"What do you mean honey?"

"There's little fuzz balls flying around everybody's head. You don't see them do you?"

"Maybe it's your quirk…?" Inko's question faded out in a puzzled tone.

Izuku could only hum at that. It would be the only explanation since he can see them and she can't. He thought his quirk was just blobs, but now there's more. First, there were blobs and now there were fuzzballs, how many creatures are there? He looked out the window trying to spot any different creatures. There wasn't any, just blobs and fuzz balls.

Everywhere

Izuku knew that the blobs appeared to cause misfortune or at least be related to it, but what did the fuzz balls do? Izuku tried to find some kind of indication by looking at the people it followed. 'Maybe they were good luck, and the slimes were bad luck?' That thought was quickly crushed when he saw a few people with blobs and fuzz balls on them.

*sigh*

Why did his quirk have to be so ridiculous? He honestly would have just been happy with gravity manipulation like his mom, or fire-breathing like his dad supposedly had. But instead, he was saddled with this complex and confusing mess. His 4-year-old brain couldn't wrap itself around it. 'What is this quirk?' He thought with desperation. He was frustrated with himself, just when he thinks he's figuring things out it gets more complicated.

He saw one man with 4 blobs on his legs trip on a crosswalk just as a car was turning. He heard the vehicle come to a screeching halt and a slam. 'Oh no!' he thought, trying to angle his head to see what happened. 'Did the man get hit? Is he ok?' his thoughts rang.

A moment later the man that had fallen stood up and walked away from the car, backward, he was apologizing profusely. Izuku observed that the man in the car was yelling at the other with a very angry expression on his face. 'I understand that he almost caused an accident, but it's not like he tripped on purpose.'

As the car man continued yelling, the other started to look more saddened. As he got more visibly upset more fuzz balls started to surround his head. 'Huh? Why him? Everyone else had only one or two fuzz balls following them, but now this man had 8 hovering over his head.' Izuku thought it over for a second. 'Maybe how the blobs like bad luck, the fuzz balls like bad emotions?' The man then bowed really low and ran off, with 4 blobs on his legs and 8 fuzz balls trailing after him.

The light turned green and their car went back into motion. As they continued on their route, Izuku tried to spot another person with as many fuzz balls as the man, but he couldn't find any. 'It's got to be negative emotions. He was being yelled at when more started following him.' He speculated. There wasn't much Izuku could do to confirm his theory about them since he was in a moving car. He wondered why there weren't any of these fuzzballs around when he was playing with Kacchan. 'Maybe it was because we didn't have any bad thoughts? Wait, they might have not had any bad thoughts, but he sure did.' Now that Izuku thought about it, not a single blob had tried to attach themselves to him. Sure he picked them up, or he ran into their course of movement, but they hadn't tried to go on him like everyone else.

'Ughhh more questions. It's giving me a headache.' Izuku ruffled his fluffy hair back in frustration. He wanted to just stop thinking for a second, but he couldn't he was too curious for his own good.

'Ok,' he thought trying to organize his thoughts 'there are three major negative emotions I can think of, sadness, anger, and anxiety. Then there is Guilt and embarrassment.' Izuku idly scratched his cheek 'Kacchan was super angry at me the other day but he didn't have any fuzz balls near him so that rules out anger. The man that was on the road definitely displayed embarrassment, guilt, and maybe even sadness.' He concluded. These would be the three emotions that his theory would run on.

Their car came to a halt in the store's parking lot, and he and his mother stepped out of the car. Izuku decided he would observe the other shoppers for fuzz balls on their shopping trip. They were carting past the dairy section when Izuku spotted a woman with 5 fuzz balls above her head. He observed her facial expression, there was a prominent frown on her face, and her eyes were red like she had been crying for a long time, or hadn't slept. She was browsing the variety of ice cream options and seemed to be deciding on Chocolate chip cookie dough or plain chocolate. His mom was distracted with different dairy products, so Izuku decided to test his theory.

"Excuse me miss, I really like your shirt." It honestly was a cute shirt, it just looked worn. Izuku took notice that one of the fuzz balls flitted away, leaving only four above her head.

"Oh, uhm-uh- thank you?" She seemed surprised to get a compliment, from a child no less.

"It's no problem. Are you sad?" he asked concerned.

The lady seemed to choke on the air a bit before she answered. "Oh, uhm yes I guess a bit, I just broke up with my Fiancée." She sounded like she was about to start crying.

'Well, that confirms that the fuzz balls like sadness.' He thought. He just had to confirm one more thing, he walked up to the lady and gently patted her back, telling the fuzz balls to go away. Like the blobs, the fuzz balls flitted away and started to aimlessly roam the store.

"It will be ok." Izuku said while awkwardly patting her back. Not knowing what else to say, Izuku simply walked away. The older lady just stared kind of baffled at the retreating four-year-old.

He was satisfied to have figured out another part of the puzzle that was his quirk. So there was bad blobs and bad, what he is now going to refer to as cottons since they reminded him of cotton balls.

Izuku's attention was brought towards a loud slam from across the store near the snack aisle. The boy peeked his head over, due to where he was standing he could see the beginning half of the aisle. There was a man that was lying face first on the ground with bags of chips on top of him, he appeared to have tripped into a display stand. Izuku watched for a moment and noticed that he only had one blob on him, and now there were several more crawling towards him. It was almost like they were… feeding? Izuku brought his moms' attention to the man in need. He and his mom speed walked over towards him.

"Are you alright sir?" His mom asked leaning over to help him up.

The man seemed to awkwardly chuckle "Ahhhaa yaa I'm fine, my feet seem to have a mind of their own today." He said while hosting himself up and brushing off his pants, his hands sweeping through invisible blobs. He looked slightly guilty that he made such a scene in the store as people were asking if he was ok when they walked past. He could only nod and say he was fine, which seemed to increase his embarrassment. He had a few cottons floating above his head they seemed to thrive in his guilt and embarrassment. That checked off two more emotions on Izuku's mental list.

Izuku bent over to help pick up the bags by the man's feet, sneakily touching the man's exposed ankle so he could command the blobs and cottons to go away. Once the mess was cleaned up they went separate ways, the man giving a few "thank you's" for the help. They were waiting in the checkout line when Izuku's thoughts started to take up all of his attention.

'The blobs and the cottons seem to be feeding off people's bad luck and bad emotions, but are they causing them? He originally thought they were causing them but maybe that wasn't the case at all. What if these creatures were just assisting in the events? Like an amplification. And why on earth did they seem to not feed off him at all?' Izuku's thoughts were interrupted by his mother lightly tapping his back.

"Izuku you're starting to mumble." She said amused.

His cheeks heated up at that, mumbling was a bad habit he started to develop a few months ago. He just had so many thoughts and ideas, they started to spill out of his mouth. Sure they weren't thoughts and ideas most four-year-olds should have, which tended to freak people out, but he couldn't help it that he was smart for his age.

His mom had paid for the groceries and the started making their way towards the exit, two blobs started to crawl up his mom's legs.

'Nope, I don't think so.' He thought while grabbing his mom's hand. He forced the blobs to retreat, he would keep his mom safe he mentally promised. They made their way through the automatic sliding doors and stepped outside, but what he saw when they exited made Izuku stop in his tracks. His mom had kept going and noticed the slight resistance, she turned around and made a questioning face.

"Izuku, is something wrong?"

He didn't answer.
