Unexpected happenings

It was a lovely day at the UA. Currently our fighting heroes were stick within the tortures of Mr. Aizawa. Mitsuki banged her head on the table in frustration. She hated studies but her dad always told her it was necessary of a hero. She looked around and smiled as she noticed her friends. Jirou was listening to music...mind you discreetly, Momo was being her normal self by paying attention though she found it had to figure what Hagakure was doing, Ochako was trying I to doze off, Mina was long gone and Tsuyu was trying to pay attention. She smiled. Ever since her mom had died she had had a hard time making friends since people wanted to be her friend because of her dad but these girls were the first to like her for her and she couldn't agree for better girlfriends.

She got out her notepad and filled to a random page before beginning to draw. Mitsuka was a girl with long blonde twintails and violet eyes. She had joined the UA due to recommendation considering that her dad was All-Might.

She sighed. Nothing interesting happens anymore. She wanted nothing than to face some sort of interesting and complicated situation. She was generally shy around others but when you get to know her she's friendly and yearns for adventure.

Mr Aizawa had strolled to her desk and looked under her desk. He removed a book only to find hasty notes all over it.

"I can't believe after all this year's you don't trust me, Mr. Aizawa."

He quirked an eyebrow.

"Oh come on at least I'm not that dumb with a quick temper not that I'm pointing fingers." She pointed towards Bakugou who sat next to her.

"OI! WHAT THE FUCK IS YOUR PROBLEM?!"

"I bet you couldn't last an hour without swearing."

"I COULD FUCKING DO SO!"

"Wanna bet?"

Bakugou fumed as he reached his hand out when Mr. Aizawa slapped it away.

"No bets in my class, get back to work."

Hardly had he turned when he caught a glimpse of the two students shaking hands.

"I thought I said no bets."

"Mr. Aizawa if you knew a person would lose during a bet and would guarantee you money, would you take that opportunity?"

"Yes..."

"Then how stupid am I not to agree to bet with anger issues over here for 1,000 yen."

"WHY YOU LITTLE..."

"Enough, let's just get back..."

Mr Aizawa was interrupted when there was a loud crash in the training grounds which shook the ground.

"WHAT THE FUCK!"

"W-what's going on."

Before anyone could stop her, she had run out of the class.

"Mitsuka!"

She had run towards the crash. She felt an odd pull from whatever it was. Mitsuki reached to the site just in time to see a girl rising up from the crater. The girl had short brown hair and she wore a purple right fitting jumpsuit and brown loose gloves and boots. Mitsuki got in a battle stance as the rest of the class came in.

"WHO THE FUCK ARE YOU?!"

Mitsuki smirked at the blonde.

"You know you owe me, right."

The blonde narrowed his eyes as he looked away which brought a mischievous grin to her face.

"Let me rephrase that...who are you?"

The girl in question who could be no older than fifteen lifted her head and revealed dazzling blue eyes which widened in recognition.

"Aunt?"

"AUNT!"

Well Mr. Aizawa knew one thing for sure. This would take a while.

Mitsuka could only gape in shock.

'Well this is interesting.'

But Mitsuki had a gut feeling that those weren't the only surprises.

Little did she know that the arrival of this mysterious girl would change everyone's life.
