Chapter 4

"What do you mean? I just set off an explosion at your damn face! You don't even seem phased! Am I that weak!?" Katsuki yelled at her thinking that she didn't even feel it.

"Did I say that? Because I don't recall ever saying that you're weak. Did you set off an explosion right at my damn face? Yes, yes the fuck you did. Did it hurt and still hurt like actual hellfire? Yes, yes the fuck it did and does. But I want you to tell me, what do you mean by Izuku's not my brother? Were Itsuki and I not, adopted by Inko? Because I'm pretty sure when we were 13 we got adopted. Are our Surnames not Midoriya now? Doesn't Itsuki and I being adopted by Inko make Izuku our brother even if it's not by blood? Because if not then what the hell am I?"

"I don't know. What are you? Well you're a bitch that needs to be protected, because you're weak." He said back to his normal self.

Mizuki put her arms over her chest as red energy surrounded her, she said, "Try me Meinu!" Needless to say Katsuki was mad.

Katsuki throws his signature right hook at Mizuki . She grabs his arm as red energy surrounds hers, and flips him over her. He coughed up small bits of blood as his back hit the ground. He turned over onto his stomach and began pushing himself off the ground. He looked up at her as blood trailed down his chin.

"Still think I'm weak and need to be protected!?" Mizuki said, venom lacing her words.

Katsuki looked away, still kneeling in the dirt.

"Ya.. that's what I thought..." Mizuki said with tears welling in her eyes. "Stay away from me and my family, Bakugo."

Mizuki pulled a hoodie out of her side bag, put it on keeping the hood up to hide the mark on her cheek, then walked away.

When she got home she went straight to the bathroom. Inko asked why she had a hoodie on considering the weather, but Mizuki ignored her. When she got to the bathroom, she closed the door and took the hoodie off. She looked at herself in the mirror then sighed. She cleaned the small cuts and burns on her cheek then covered it up with a bandage, hair spray, and her long, thick hair, by wearing it over the left side of her face.

After she was done covering up her cheek, she went to her room, and grabbed one of her mothers old hoodies. She put the hoodie on a pillow so it would be like she's able to hug her mom.

Itsuki was in there playing on her laptop and asked her what's wrong but she ignored him. He pushed herder, knowing something was up.

She finally snapped and yelled, "Nothing!" Harshly.

Itsuki walked over to her and pushed her shoulder.

"Aye." Itsuki said as Mizuki turned to look at him. "Are you sure..?" Mizuki looked away and shook her head. Itsuki frowned. "We don't need to talk about it if you don't want to." He said as he sat down next to her and pulled her into a hug. Mizuki turned around and hugged him back.

Around 5 minutes later she heard a knock on her bedroom door.

"Come in." Mizuki said trying to sound normal. When her and Itsuki looked up they saw Inko.

"Oh, hey Inko." Itsuki said.

"Hi sweetie, can I talk to Mizuki alone?"

"Sure." Itsuki said getting up from the bed after giving Mizuki one last reassuring squeeze. Before he walked out, Itsuki looked back and smiled.

Inko walked over to Mizuki's bed and sat down next to her.

"Are you ok? When you got home you seemed.. well mad." Inko said worried.

Mizuki faked a smile even though it hurt to. "Ya, of course. I'm fine."

Inko smiled. "Ok, I love you. And I love how you're wearing your hair now, it's cute."

Mizuki smiled, "Thanks. I love you too." She said as Inko left. Mizuki went to her open window and stared at the trees. As she watched the cars go by, heard the birds chirp, felt the cool air blow onto her burnt face, and her scars from the explosion. She then decided she would go train for UA tryouts, even though they were still almost a year away. She got into some workout clothes and grabbed her bag with all her equipment inside. She grabbed Itsuki then told Inko they were going out. Itsuki and her walked to a nearby forest where Izuku and Mizuki would normally train.

When they got there Itsuki played on his phone while Mizuki put her bag down and got out her pad that she had to rap around a tree for a target. She then got into her fighting stance and concentrated. She began to feel the powerful energy flow through her and leak out of her skin. She pushed the energy to her arms and hands. The energy moved exactly where she wanted and how she wanted.

She punched and kicked at the tree for 10 minutes before she heard it. Explosions. Explosions that were so big and so loud that they gave her flashbacks to the day her mother died. She tried to get it out of her head and move toward the sound, stumbling around.

When Itsuki saw how she was acting, he knew he had to do something to calm her down. He knew she wasn't fully over what happened the year prior. Small shocks were sent through his body as he grabbed her arm that was still covered in the flickering energy that sent continuous shocks at Itsuki. As the explosions went on the flashbacks got more and more vivid as Mizuki imagined the pain her mom must have felt. Dying alone, without her daughter or son by her side. She screamed. It was like she was back on that day.

"N-no! Mom! I need to help!" She was so scared. She fell to the ground. She felt like her mother was still in that dammed building, and she had to help.

"Shhh, Mizuki it's ok. You're safe. You're ok.. you're ok..." Itsuki said trying to calm Mizuki down

"M-mom..." Mizuki passed out from the physical and mental pain.

Itsuki sat there for a minute holding Mizuki in his arms. Trying to think about what he should do. He decided to stay for a few more minutes to make sure Mizuki was ok.

After around 5 minutes of Itsuki trying to wake Mizuki up, he decided to try and carry her home. So Itsuki grabbed the bag, throwing it over his shoulder, and picked Mizuki up.

Back at the house, Inko and Izuku where worried. Inko asked Izuku when he got home if he was with Mizuki or Itsuki, but Izuku said the last time he saw Mizuki was at school, when she said she would see him at home and hadn't seen Itsuki since that morning. Needless to say, they were a little worried.

20 minutes latter Itsuki was at the door to the house. He put Mizuki down and opened the door to see a worried Inko and Izuku.
