MHA : Venom

It did not take too long before Katsuki began to slowly, but surely, revert back to his old bombastic and annoyingly cocky, self. He only remained flat out sulking for about 3 weeks or so.

After that, he began to act more and more like how Izuku remembered him.

That's not to say that he hadn't changed though. He certainly had. Some major, some minor ways.

In classes themselves he had drastically changed, having gone from always being loud and obnoxious, to being much more quiet, and seemingly hyper-focused on whatever lesson the teacher was teaching. He still had outbursts in class(especially whenever someone dared to bring up the villain incident. That was a surefire way majorly piss him off) but overall he was way less aggressive during the actual classes.

Except for gym class.

If Katauki had become less aggressive when teachers actually talked, it was as if he had instead transferred all of that aggressiveness and channeled it into gym class instead.

Anytime they ended up at some competition(generally a ball game) he would turn into the most aggressive competitor Izuku had ever seen. Even in cases where it wasn't a direct competition he was still hyper-aggressive against pretty much everyone.

And it wasn't just how he acted either. Izuku wasn't sure if he had become way more aware of such things after unlocking his quirk, or if he was simply hypersensitive when it came to how Katsuki was, but he quickly began to notice that Katsuki began to put on muscles.

He had always been an athletic guy, but it was obvious that he had begun to majorly work out, the way his arms developed from pretty muscular, to just being jacked.

For his own part, Izuku was glad that so far his powers didn't seem to majorly affect his muscles in looks. Other than burning off any excess fat he might have had from before, through his daily training, Izuku didn't look any different than everyone else in the class.

One major downside about hiding his powers was that he pretty much had to deliberately fail his gym classes in everything that wasn't just endurance training, running, or jumping exercises.

He just didn't have enough control yet to actually pretend to be mediocre. He was either amazing or terrible. Not much in between.

The greatest change about Katsuki in Izuku's mind however, wasn't the changes to his temperament, or his seeming obsession with school grades.

No, it was his attitude towards him in particular.

When he had first come back to school after the incident, Izuku had thought he would enjoy a brief reprieve from Katsuki's bullying until the blonde boy got back on his mental feet so to speak.

Instead, what he got, was what he had gotten at the start. Katsuki ignoring him. Outside of gym class, Katsuki seemed to have made it his policy in life to pretend Izuku didn't exist. At all.

Izuku had no idea why this was apparently Katsuki's policy going forward, why the villain incident had changed him in this specific way.

To be honest, though, he didn't really care all that much either.

He had no doubt that if the two of them got into Yuei together, this calculated indifference would vanish like morning mist before the sun, but if Katsuki was going to leave him alone for the rest of middle school, he would take it. With open arms.

As for the school work itself… Well, it wasn't as if that much had changed. He still diligently studied at school to the best of his abilities, that part hadn't changed at all.

The main difference was outside of school.

As the weeks had gone by, he had begun to have a very specific routine.

He would go to school in the morning, go home immediately after the last class was over, do all his homework immediately when he came home no matter if he spent 5 hours on it or 1, then if he had spare time he would go out into the city to look up hero battles(He'd stopped taking his books with him to school, so he didn't get to do it in the mornings anymore) until 17.30, when he would head to the woods to train, spend 3 hours every single day doing one type of exercise as much as he could, then go home and get cleaned up, go to bed and rinse repeat the cycle.

The exception was his weekends.

During his weekends, at day, Izuku threw himself back into trying to recreate his lost notebooks, as far as he possibly could, desperately trying to remember and look up every single hero he could ever remember seeing.

Towards the night, he went to the woods and did his exercises.

It was a very rigid regiment, but frankly, he felt more alive in these months than he had since… Actually, scratch that. Izuku had never felt more ALIVE in his entire life than he currently did.

While he certainly didn't enjoy going back to his hated middle school, without katsuki doing everything he could to push him down, he could grit his teeth and bear it.

In his mind though, the real education he had right now, was his training. His physical education, that would be the rock upon which he would build his entire future.

And he was making progress there too.

While he still hadn't become capable of punching without just turning whatever he touched to paste, in every other field he had improved.

In particular his jumps had improved most of all. He had done some math on it, and if he was right, he had roughly one more month of jumping before his balance reached the level he was training so hard for.

His grip control had also drastically increased so now he didn't accidentally crush things in his hands anymore. He had accidentally broken 3 different door handles on the bathroom and one on his own door, and he'd had to go back to the beach and scrounge for replacements every time.

Then there was running… Oh, the running.

If there was one part of his new powers that just gave him joy, it was running at top speed, with not a care in the world, sprinting through the woods, making countless on the spot turns to avoid trees… Of course, it was far less fun to stumble and accidentally hurt himself, but that had become far less of a problem as time went on.

He'd also broken 7 trees so far, accidentally running into them, so he'd decided to only do this kind of training in the deepest part of the woods, far away from his regular spots.

For once in his life, absolutely everything was going great.

The one thing he still hadn't put to the test was his ability to heal himself.

That changed on his 36th training day.

...

Izuku speed through the forest, enjoying the thrill, as he twisted and turned as he moved through the foliage and the forest grounds.

It was at the end of his training session for the day, and he was heading back towards his regular grounds.

He had become familiar enough with the area in a way he had never been in his younger days when he Katchan and the rest had wandered these woods.

These woods had once been an adventurous playground for Izuku, where he had explored what had seen like a brand new world, full of possibilities.

Now that was kinda what they were in truth, not just the overactive imagination of a child. These woods had become something he knew like the back of his hands, where he put everything new about himself to the test.

Happiness.

The feeling coursed through his mind, as it always did when he ran like this.

His quirk wasn't shy about making himself felt, and there was rarely a day where izuku didn't get some emotion that wasn't his own running through his head. However, of all the feelings his quirk had, happiness, true joy, was seemingly only reserved for the times where he ran to the very limit of how far he could push himself.

It just heightened how enjoyable these sessions of sprinting was for him. With all the rest, there was a sense of struggling, of work, of training to master something. But running was different. Moving at great speeds just felt… Right. Like this was what he was born to do.

It was the one part of his powers that he had instantly UNDERSTOOD, from the moment he really began to really use it.

He practically flew across the forest ground, made a quick jump over a rock, sidestepped out of the way of a large tree, smashed through some branches that snapped instantly the moment he touched them. Never stopping, always moving.

He wondered how it would feel when he began to combine this speed with actual real jumps, not just clearing hurdles.

He reached a small river that went through the forest, flanked on either side by dirt walls.

Izuku should have just jumped the small ravine, trusting in his relatively good new balance to carry him across and safely on the other side. However, he knew from experience that the sides of this ravine were just packed dirt and unstable dirt at that. He'd fallen into the water here before after the ground literarily crumbled beneath him.

Instead, he made a hard turn right and kept going along the river. The goal was a rather big log up ahead, that he'd discovered and made note off long ago.

He'd used it to cross before, and he had yet to fall off it.

As he neared the log, he made another quick and direct turn, jumped up on to it, maybe one third across, he instinctually bent down, preparing to make the jump across the rest of the log in one go.

The force of his legs as he kicked off broke the decades-old, weathered, waterlogged and rotten log beneath it in half, and he slipped sideways as the log collapsed out from under him. Then PAIN shot up through his right leg! He screamed as he fell down into the water, the now two pieces of logs falling with him at an awkward angle.

The water in the river engulfed him for a moment as the shock and panic of the sudden pain took him.

Then he wrenched his head and an upper body above water, which just made the pain even worse!
