He couldn't get his mind off the naked girl from the previous day. After successfully completing garbage duty he had returned to the dorms to discover everyone else from class 1-A in the commons area having a good time. Their smiles and bright energy bringing a sense of longing as he watched from the sides.

Wordlessly he had walked back to his room without a second glance.

"Maybe one day I can join you guys..."With that in mind he had changed into a pair of sweats completed with boxing gloves as he took a few jabs out on the sandbag in his room.

His mind still on the rather strange encounter as he furiously delivered strike after strike against the worn bag. Sweat trickled down his face as he took a small breather.

"I wonder if I'll see her again."He would soon regret those words very soon.

"Too soon..."

He was in home room as he glared at the rather ecstatic blonde before him as she stood in front of the class along with two other people. A girl with periwinkle colored hair that nearly touched the groud and boy with a ominous emo edge to him.

And finally the girl know as Mirio Togata before him. Her uniform clung to her tightly holding her rather large bust at bay. He muscular arms stood out mostly that had various scars on them that peaked Izuku's interest slightly.

"These are U.A's top 3 students also known as the big 3." Aizawa stated dully,but everyone else in class stared in awe at the three with excitement and anticipation.

"Wow there so cool!" Tooru voiced her opinion as the rest of the class nodded in agreement.

"They will be helping you in your next assignment when you enter your hero training. I'll let them take it from here." Aizawa said seeping back into his yellow sleeping bag.

"So I know you all have a bunch of questions, but first let us Introduce eachother. I'm Nejire Hado!" The girl with periwinkle hair spoke as she gave a small bow.

"I'm Mirio Togata!" The blonde boasted with bright smile making Tokoyami cringe slightly.

"Too bright..." He whispered to himself.

The one with a emo edge just glared at the class scaring them slightly. With out a word he faced the wall confusing most of them as he began to speak.

"I'm...T-Tamaki Amijiki..." The teen said shyly.

"He's shy!" The whole class thought in unison.

"I'm also really sorry to cut this short,but I kinda wanna test my skills against you guys." Mirio spoke honestly with a slight edge in her smile. Everyone stared in slight confusion except for Izuku who saw a look of excitement in her blue eyes.

"She's definetly strong..."

"So meet us in the training ground in 10 minutes!! See you there!" With that said the three left not before Mirio gave Izuku a playful wink and blown kiss towards Izuku.

"Can't wait to see how strong you are Midoriya-san!" She exclaimed leaving behind a slightly flustered Izuku.

"Do you know her Midoriya-san? Kero." Tsuyu questioned as he gave off a light frown.

"I just ran into her is all." He said vaguely leaving out the part about seeing her naked.

"Well I hope you guys don't plan on just sitting there. Make your way to the training grounds." Aizawa spoke from his sleeping bag.

Izuku watched as everyone got ready to leave as he had a strange thought to himself.

"Should I mention Senpai's quirk?"

Deciding to withhold this information he gathered his things to make his way to the changing rooms.

"Still...how strong is she?"

"Glad you guys made it!" Mirio said as she stood infront of 1-A. She was now dressed in the standard U.A training uniform as the other two stood to the side along with Aizawa and surprisingly Todoroki as well.

"Wait are we just gonna be fighting you?" Kirishima questioned as Mirio gave a hard nod.

"Yup! Promise not to hold back on lil old me!" She said with a bright smile.

As soon as she spoke her words everyone readied their battle stances. Izuku opted to stay in the back with a pair of Tofas at his side as he tried to analyze the situation.

Not a second later did a few students like Sato ,Iida, Kirishima and Ojiro charged towards Mirio with full force ready to end the fight quickly as possible.

In a blink of an eye Mirio had vanished before them just leaving the traces of her clothes on the ground.

"Wait where did she go?" Ojiro questioned as everyone looked around.

Izuku readyed himself as he looked around his perimeter.

"She used her quirk...but what is it?"

"AHHHH!!" A sudden scream was heard from Jirio as she was kneeled on the ground holding her stomach tightly. Standing before her was Mirio with same grin as before ,but stark naked surprising everyone.

Mineta and Kaminari were the first to go down as blood gushed from their noses wildly. The rest either had server blushes or looked away from the rather naked curvious sight of their senpai.

Doing that though was their ultimate mistake as Mirio delivered swift and powerful blows to each student with ease.

"POWERRRRRRRR!" She roared as she struck a pose over every fallen student.

Izuku was the only one left standing as he kept a safe distance from his smiling senior.

"Guess your the last one Midoriya-san. Don't disappoint me!~" Mirio spoke as she vanished into the ground once again.

"What a powerful quirk..." Todoroki spoke as he watched as almost all of his class was defeated In a blink of an eye.

"You would think that...it's not just her quirk. This is Mirio-chan's true strength." Tamaki spoke softly as Nejire nodded her head in agreement.

"The big three aren't just the strongest in U.A,but also those closest to be the top heroes. " Aizawa spoke droningly surprising Todoroki.

Izuku looked out into the distance cal.ly as he readied his Tofas. Taking a small breathe he dodged a rather powerful punch from behind him with ease surprising Mirio and Nejire.

"Sorry senpai, but those tricks won't work on me." Izuku said taking a side step to keep his distance from her.

Mirio looked on confused for a second before her eyes widened into sparkly blue orbs.

"I knew you wouldn't disappoint me! Get ready Midoriya-san!" Mirio said excited as electrical energy started to form around her as she swelled with power.

"Ah crap." Izuku said as he prepared to defend himself from this one sided fight.

"let's at least get one blow in."

With that he leapt into battle at the ready as Mirio smiled widely.

"GET READY! POWERRRRR!!" Mirio roared as she swung her first towards Izuku with all her might.

"Oh shit." Was all Izuku thought before he felt his body being thrown into the distance.
