"We have a new student so please treat her well." Her kindergarten teacher said smiling as both of them stood in front of the class.

"My name is Suirozaki Ayane. Please take care of me." Ayane said with a large smile.

Being a social and cheerful person Ayane was able to fit in from many of the children she got along with Midoriya Izuku,A cheerful boy with green hair, the most.

And being friends with Izuku she also automatically became friends with Bakugo Katsuki.

...

"Aya." Bakugo said as he walked along with Ayane towards school.

"What is it, Katsuki?" Ayane replied with a smile on her face.

"I have something to show you." Bakugo said as he showed his palm and a few seconds later sparks started to show. It wasn't explosive rather it was quite small and also very beautiful as if it were fireworks.

"Woah!" Ayane said with wide eyes shining with amazement. "You got your quirk! And it's so cool. As expected from Katsuki!"

"Yeah!" Katsuki smiled proudly. "You're the first person I showed my quirk to!"

Ayane stopped and stared at Katsuki, then a huge smile emerged on her face again. "Woah! That makes me feel so special,Katsuki!"

Bakugo then looked down and muttered in a low voice. "That's because you are..."

"Hmm?" Ayane who didn't hear him due to her being too amazed by Bakugo's quirk, looked at him.

"I didn't say anything, you idiot!"

"Ahahaha! Since Katsuki showed his quirk to me first, I'll also show mine to you first!"

"It's a promise!"

After that things between Bakugo who often bullied Midoriya and Ayane who always supported Midoriya, went down hill.

...

Ayane was running towards the playground where Katsuki and Izuku would usually play. It's been a while since Bakugo and Ayane hung out like they used to but then she still remembered their promise.

Her quirk appeared quite late so she thought she was quirkless like Izuku but her parents who were doctors assured her that her bone structure , a common method used to identify if a person was quirkless or not, showed that she was not quirkless.

She smiled to herself again as she remembered her quirk. It was quite powerful if she must add.

She finally saw Katsuki's back along with two other class mates of theirs.

"Ka-"

"That's mean,Kacchan." A small whimpering voice was heard making Ayane stop. "Cant you see he is crying? If you keep going...I'll never forgive you!"

This made Katsuki and his group smile and activating their quirk.

"Even though your quirkless..." Katsuki smiled ,bringing his hands together "..you're pretending to be a hero, Deku?"

This made the boys rush towards Izuku.

"Stop!" Ayane shouted quickly making her float and stop in front of Katsuki, arms wide making them stop.

"Aya..."

There was silence among them.

"Katsuki, I already told you to stop bullying others!" Ayane shouted. The girl used her quirk. An almost transparent tail or rope emerged from the girls tailbone passing through her cloths. The tail rising high,tip pointing towards Bakugo .

"Huh?! Just because you got your quirk doesn't mean you can win against me." Bakugo shouted overcoming his astonishment. His close friend had finally got her quirk but then she is using it to defend stupid Deku.

"What should we do Katsuki?" The classmate with wings asked.

Katsuki stopped and looked at the was always like this, always defending Deku from others ever since they were young. Being all cheerful and always smiling but at the same time had that strong sense of justice.

It annoyed him.

"Let's go" Bakugo said as he turned around making the other two also follow him. "Aya destroyed all the fun."

As he walked turned his head slightly and saw both Aya and Izuku bend down helping the other child up.

"Are you okay?" He heard Aya ask as Deku lifted the boy up,concern clearly heard in her voice. "Of course not...Why did I even ask?Let's get you treated!" The girl continued as she smiled.

That girl was a hazard herself being all didn't even know how to tie her shoelace up until recently, Bakugo had taught her. Now she was here trying to help others. How stupid!

That stupid girl also didn't keep her promise. Bakugo thought.
