"Hummm... Aah..! Bleh!" You stare at the mirror taking in the adjusting features of your newfound quirk.

"Can you stop already?" Tora groaned laying back on your bed while you stare at yourself in the mirror of your vanity.

"If you don't want to listen to me, you can just wait outside." You lightly glared at him. "No way, your brother has sent daggers into my head with just his eyes! I am not risking loosing my head." The boy interjected.

"Ugh.. Its just that I am kinda getting used to my new features." You explained.

"I mean look, my eyes are turning entirely yellow, my teeth are sharpening and my ears are turning into fins!" You grabbed his collar and shook him in a panicky way.

"Ey get off!" Upon you immediately dropped him making him grunt in pain while you turned away.

"And lastly this tail is just like crazy!" You exclaimed gesturing to the tail that is just leisurely swaying without a care in the world.

"Look calm down, despite your tail being at fault for -I forgot how many incidents at school- it is still part of you."

"How are you so sure!?" You screamed.

"Because I have a quirk that is like a freaking shadow!" Tora yelled back gesturing at the glowing half image of a young saber tiger floating above him like an armor.

"Oh right, but still at least your tiger is obedient, I don't know what mine wants.." You sighed at the tail who made no effort to respond.

"Look, we are going to the doctor and we will see how your mutation is going." Tora says walking to the door opening it.

"Your right, I could use a visit to Se-" you were suddenly cute off with a loud bang off the door and saw Tora leaning against it.

"Can you please tell your dog of a brother to stop guiding your room?" Tora bluntly spoke nudging his thumb to the direction of outside your door.

"You unleashed the wolf you gotta deal with it." You shrugged your shoulder with a smirk, already knowing that Tora had a talk with Katsuki just not the content of the conversation.

[--]

"Alright (Y/N), that's it for your therapy, just wait for your brother to pick you up." Ms. Kōzō said sitting back on her chair while you stretched exhausted.

"Is Sen here?" You asked.

"Oh yes, she is in the room 3 doors away towards the stairs." With a smile you thanked the doctor and walked out to be greeted by Tora.

"You done?"

"Aaaah!....." You lightly screamed before trailing off. "Don't do that..!" You whined.

Tora rolled his eyes and walked off. "Where are you going!?" You asked

"Aren't you gonna meet this 'Sen' person?" He answered not looking back catching on what he meant you quickly rushed after him.

"Sen!" You knocked on the door where she resides.

"In a minute!" Her voice muffled out.

And following that voice were series of crashes and thuds that were pretty loud...

"U-Uh...Sen?"

With a few more seconds to spare the door finally opened to reveal Sen who huffed in exhaustion. "Hi (Y/N)!~" she sang.

"What were you doing in there..?" You asked with a nervous smile as she blew a raspberry.

"Pfft! Nothing dangerous!"

Tora rolled his eyes at her words. "I feel so safe..". Hearing the comment Sen snapped her head at him.

"And who is this Numbskull?" Sen glowered at him with uncertain eyes.

"Ah Sen! This is my bestfriend, Tora!" You say. Sen gasped dramatically and tackles you in a tight hug. "Aren't I your bestfriend?" She asked in shock.

"I can have more than one bestfriend, you know" You laughed at her while Tora groaned in annoyance.

"Well why is the slob also your bestfriend? He seems like a big fat stick in the mud.." Sen pouted.

"Excuse me!?"

"(Y/N).. Did you hear something? All I hear is blablabla..!" Sen smirked at Tora's fuming scowl.

"Now now, let's not start world war bff, I thought I could use your company before I go back home." You stood before each other's burning gaze to calm down the atmosphere.

"Oh sure! Come in!" Sen moved to the side so you could enter but before Tora could she blocked the way.

"Not you, you stink furball.." She deadpeanned holding her nose.

"...what?" Tora growled.

"I thought you have better ears." Sen teased watching Tora shake.

They glared at each other, each taking a step forward Tora's quirk firing up while Sen's eyes glowed. But before hell could break between the two a crash was heard inside the room.

"(Y/N)!? Are you okay?" Both looked into the room and saw you hanging from the ceiling by your tail.

"Ha....Y-Yeah..! I'm fine." You sighed standing on your feet. "Anyway what's taking you two so long?" You asked making them both shrug.

"Oh nothing just introducing ourselves!~" Sen chirped and showed a hand to Tora.

"Hi I am Sen Kōzō, and you are?" Looking at her hand Tora forced a smirk, despite how dark it looked and roughly grasped the outstretched hand.

Both squeezing it as hard as they can. "Tora Seishin.. Hope to chop your head of soon.." Tora growled through gritting teeth.

"Not before I take the chance first..!"

Away from the two you sighed with your tail flicking in dismay.

"I am worried for the sake of the world..." You spoke to it, watching both forces try to tear each other down with their death glares.

===============================
Hey, Hey! How are you all doing? Are you all doing fine? I got this song of Doki Doki stuck in my mind. My trio is almost done so heads up for any soon chapters if you guys have read the Author's message in my other book, but for those who haven't.

I am currently on a trip but fortunately it's almost over, all I have left is my music recital and I am free.

Oh my gosh... 5 days without practice.. I am doomed... (;-;)

But anyway! This maybe shirt cause I am in a bit of a rush to finally get to the climax of this arc! And then we will be entering the series!

But be mine that I also had some of you guys request some scenarios of maybe alternate universes. So heads up for those and just to make a disclaimer. Those are not part of the main story.

You can request too, just make sure it is with at least Katsuki's Sister! Reader .

Thank you for your time!

Peace!X3
