Katsuki reached his favorite spot in the woods then screamed in rage and frustration before letting lose a volley of explosions, leveling more tree's and creating holes in various spots. He grabbed a rock and tossed it with his quirk delaying the explosion until it smacked into an already crumbling boulder, the former boulder was no more and all that remained were small sized rocks.
"If All Might punched that there wouldn't be anything left, I'm not strong enough" growled Katsuki.
In his head he knew it was Izumi's fault for eating his quirk, it was his power, his energy and he hated her. He hated her for ruining their friendship, for ruining their mother's friendship, it was her fault that her father had burned his auntie, it was her fault for not getting the stronger quirk of her parents, it was her fault everyone was scared of her, it was her fault that he would have to one day kill her when she went evil.
"I kill her!" screamed Katsuki before unleashing another volley.
With each blast the sentence "I'm not strong enough" repeated over and over.
"I'm not strong enough"
"I'm not strong enough"
"I'm not strong enough"
"I'm not strong enough"
His arms began to hurt so he lowered them and looked around the woods, smoking crates and burned trees littered the landscape. He saw a few fire and using a trick he learned as a child grabbed dirt and charged it with his sweat and tossed the clumped dirt into the fire's causing the dirt to exploded and snuff out the fires. He thought he could only make instant explosions but when he knocked Izumi out of the tree he had delayed the explosion until he was sure he wouldn't hit her but that had been a mistake. She had turned into smoke and then threatened to devour their quirks like vampire's of per quirk times did with blood. He had tried to protect her before but after she said that, no one wanted to be friends with a monster, one who was constantly feeding off them.
"It's my quirk you ungrateful freak!" screamed Katsuki.
His arms rested again he unleashed another volley.
"I'm not strong enough"
"I'm not strong enough"
"I'm not strong enough"
"I'm not strong enough"
All the extra's at his school were stupid cowards, Izumi wasn't scary, her quirk was evil but they shouldn't be worried, as soon as she did anything, he could stop her, he wasn't scared of her, he had never been scared of her and the next time she stepped out of line he would prove it. He wasn't a coward, he didn't fear her, she feared him, why else would the monster let all those damn extra's walk all over her. He wasn't afraid and he would prove it once he was strong enough. She would never eat his quirk because he was stronger and not scared of monsters.

Katsuki was happy, his parents had said Izumi were coming back to school and he could see her again. He had been warned not to destroy her gloves. When he got to class he saw another kid being carried out. He was pale and sweaty which meant Izumi had hurt him. He walked in to see the teacher cutting her hair. He frowned as clumps of her long green hair fell from her head to the floor.
"What happened?" asked Katsuki.
"She's a freak, even her hair hurts people" said a kid with claws.
"My dad said it's not people she's hurting but their quirks" hissed a kid with all black eyes and fangs.
"We should teach her a lesson she'll never forget" said smirked a kid covered in flowers.
"But we are already in class, won't she learn a lesson here?" asked the kid with claws.
Katsuki started laughing, he didn't know if this kid was joking but he found it funny and that's when Izumi looked at him then looked away, but Katsuki saw the fear in her eyes and felt bad.
Recess.
Katsuki grabbed a ball and headed to the 4 square block hoping to play with someone when he noticed some other kids grabbing rocks and balls. He overheard them saying they were going to make Izumi leave. They noticed him and invited him to help. He agreed because he wanted to warn Izumi, she was his best friend. He and the other kids went looking for her until they found her in a tree. She was staring at something in the distance and hadn't noticed them.
"Hey Izumi we were looking for you, can you get down here so we can talk" asked Katsuki.
"I had hoped you idiots got the message and stayed away" sneered Izumi.
"I want to help; everyone is saying your evil and your quirk hurts people quirks" said Katsuki.
"I'm not and if they didn't touch me they would be fine" said Izumi.
"She's a lair" yelled a kid.
"Go away" demanded Izumi.
"They won't, they think you're a freak" said Katsuki.
Several kids starting throwing things at Izumi and he could stop them but then he got an idea. He covered his ball in sweat and tossed the ball, it was supposed to fly past the tree and then explode but another kid pushed him and the ball scratched the tree and exploded. Everyone started screaming as the tree crashed to the ground but no one saw Izumi until someone pointed at dark green moving smoke. It landed on the ground and began to form a person until the smoke was gone save for whisps rolling of her skin.
"Monster!" yelled a kid who ran up to Izumi and smacked her in the face with a rock.
Katsuki was shocked that some kid had done that because now she was bleeding. His shock turned to horror when she removed her gloves and grabbed him, he turned pale and sweaty and then she tossed him to the side. The cut on her head stopped bleeding and was gone as well as the other small cuts from when the tree exploded.
"Get away from me or I'll eat your quirks, you'll be quirkless and your parents will hate you forever" yelled Izumi.
All the kids rans except for Katsuki. He stood there watched as his friend became the monster they all said she was.
Izumi stared at him trying to scare him but he stared back and vowed he would slay the monster.
Elsewhere
Shinso was jogging down a new street hoping it would have a steep incline to better help with his training. He wanted to be a hero and to do that he needed to build muscle, he knew he couldn't relay on catching bad guys unaware with his brainwashing quirk forever, they would catch on eventually, so he needed to get stronger and faster. He jogged until he reached a dead end at a trash dump, he began to turn around when he noticed a sign that read Takoba Municipal Beach Park. He was dumbfounded, he had though this was place was a garbage dump but it was a park that been overrun with garbage. He decided to come back later that with sturdy gloves and old clothes he wouldn't mind getting torn or dirty. He would clean this beach and use it as a form of strength training.
"I can do this" thought Shinso.
An hour or so later he came back and started looking around. He started with the smaller objects placing them in trash bags when he realized he could also make some money as well. U.A was over 3 miles from where he was and he could try and talk to Nezu about selling them the scape he could bring them for the support classes or even trade it for something like extra credit for getting into the hero program. Shinso grabbed a small bag and began to jog the 3 miles uphill to U.A. He was sweaty and smelly by the time he reached the building. He walked into the air conditioned building and walked up to the secretary's desk.
"Hi, My name is Hitoshi Shinso, is Nezu in and does he have time for a meeting? asked Shinso.
The secretary looked at him then checked the schedule.
"I'm sorry but he is busy with several meetings today and he won't be in tomorrow, would you like me to leave a message?" asked the secretary.
"Yes please, also can I donate this to the Support department?" asked Shinso holding up his bag.
The secretary gave the support class teacher Power loader a call about a donation.
Shinso had taken a seat until he saw a shirtless man wearing an excavator shovel on his head.
"Where did you get this?" asked Power Loader.
"I decided to clean up Takoba Municipal Beach Park as part of my training, I figured I'd could make some money off this or trade it for extra credit, I applied for the hero course" said Shinso.
"I can't promise anything, but I'll talk to Nezu, instead of a donation how about a trade, some tools and electrical engineering book for this bag?" asked Power Loader.
Shinso thought about it, he realized there was very heavy stuff at the beach and Power Loader was offering him tools that would help him make it lighter, working hard was good but so was working smarter.
Shinso bowed.
"I accept" said Shinso.
"Then come with me" said Power Loader.
