Uraraka POV

She hummed happily as the warmth and sweat-drenched skin rubbed against me though I'm used to it with Katsuki. I watched as her blond hair swished back and forth her bright red eyes shining with amusement. Her tank skin glistening with nitroglycerin she started to singing this sweet melody. She practically hovered off of the ground as she skipped down the hallway the bathroom within seconds.

Not once did she look at me not saying a word to me she just kept singing that sweet melody, even as I looked at her I felt that like an idiot. The two of them looked too much like their ash blond air shimmer the same because of their quirk.

The same naturally tan skin and muscular body, I'm sure that they even have the same murderous grin that they get when they start a brutal fight. I watched as she gripped tightly to the white handle yanking lightly on the door as her muscles strained in a tight tank. "After you pink cheeks"

Her light airy tone filled with machvious joy as she held the door open for me, her brow raised a little expecting me to get my ass in the room. Her eyes shined for a moment trying to figure out why I wasn't doing what I was told. So I walked into the room listening to the sound of the leaky faucet. The white wall blinded me lightly as I walked into the room skipping over the white countertops.

I watched her hair flip over her shoulder as she jumped onto the counter looking at her legs as they dangled back and forth. Her eyes trained on me as she jerked her head towards the bathroom door. Her eyes hardening for a moment they turned demanding. "Go lock the door I wouldn't want anyone coming in or listen to the convention."

Her coy voice told me that if I didn't do what I was told then she would make me regret it. Her legs stop dangling so that I was staring at the soles of her shoes, her retractable spikes were gone but hole replaced them I'm sure that at any moment she could let off a wide expression. I watched her as I slowly crept over to the door.

Quickly turning the cool sliver lock before looking back at Kai this sly look on her face as a cocky grin formed on her face. Her soft pink lips stared back at me as I did my best look at in the eyes. But her eyes were more fierce and threatening then Katsuki could ever get though I'm sure that if I pissted him off enough then I would see that look.

"Alright, so I want to start this off by saying that if you do anything to my kitty Kat if you make him even the slightest bit upset I will kill you. That not an empty threat that's a promise I adore my brother and I won't have you hurting him…." Her voice cut off abruptly as she blinked her eyes rapidly like she was fighting off tears.

Her eyes clouded for a moment simply watching me as her bright crimson gaze dulled a little bit. Her body rigid and not as carefree as before, something about her song about her relationship with Katsuki must have meant a lot. I'm sure that is the reason that Katuski was protective of her. About all of this and one of these days, I was going to ask him about it.

"Anyway so let's chat I want to know everything how you managed to get Katsuki cause god knows that boy doesn't care about anything but being number one. Oh, and what is this I hear about you meeting my mother?" I watched her eyes sparkle with newfound enthusiasm and interest as I looked up from my own clutter thought and unspoken question.

My heart began to thud in my chest as a little voice in my mind told me that I need to be careful about what I say. I know that of Katuki his mother means a lot to him but I don't know if the same could be the same. I guess that Kai must have sensed my hesitation because she began to speak in a carefree tone.

Her index finger curled the blond hair as she cocked her head to the side speaking in a bubbling voice. "Don't worry about it be brutally honest, I'm a daddy's girl. I never liked the bitch she is a pain in the ass its the major reason that I left the county for America."

I nodded my head not really knowing if I should trust her words or not but I sucked in a deep breath before doing my best not to make it seem like I was hiding anything. But I went for it I recounted everything that I could remember from my first meeting with her mother and how things progressed with Katsuki and she squealed excitedly.

She clapped her hands happily before jumping off of the counter her boots slapping heavily against the ground. This wide dazzling smile lit up her face lighting up the room better than the overhead lights.

"That great you don't realize how funny this is, Katsuki finally finds a good girl and mom hates you. I can't wait for the awkward family dinner, you are coming tonight right?"

Her eager voice caused shivers to go down my spine as I watch her long slender arm reach out to the door. A slight grin formed on her face as she unlocked the door. I could hear the sound of the tumblers turning as she yanked it open with ease. Even though I knew that door was heavy.

Her muscles didn't even budge from moving the heaven door as we both began to walk out of the bathroom. Quickly she spun on her boot-clad heels and gave me one more dazzling smile before that dazzling grin turned into an angry sneer. "Just remember my brother doesn't let people in easy but he let you in. If he gets hurts then I will kill you."

She winked at me before running off back to the room. Leaving me there shell shocked and unable to form a word what the hell just happened. It was one of the strangest days that I have ever had and I'm sure that it is going to get even weirder before the day is through.

A Few Hours Later

I watched Katsuki sulking next to me his deep crimson eyes hazed with anger and irritation as I walked next to him just as easy going as she was in the bathroom. It didn't take us long to get out into the fresh open air. The cool summer air swirled around me as I felt the eyes of both on us. I'm sure that they all have seen the scenes that happened in the room from a few hours early.

They probably all thought that it was weird that I was so invested with what Katsuki is doing in his free time. The most interested begin Deku I could feel his cold green eyes watching me as I slowly made my way out the school gate with Katsuki grumbling by my side. Suddenly he softened as his body became less and less rigid.

Kai dance in front of us her skirt rising little too high it was a good thing that he was wearing those leggins or she would be putting on a show for us. "So what did the two of you talk about? Oh and notice how I asked I didn't sneak around the school trying to listen in on you." His hurt and rather gruff voice filled my heart as slight guilty twinged started to fill my heart.

A cold shudder ran down my spine as I thought back to the argument, what if they tell their mother in some off-handed petty comment. I looked up at Katsuki his red eyes staring at his sister. But I could see this protective worry in his eyes as he did his best not to let it show. "What is wrong with you?"

I watched his ash blond brows furrow together and dip down like he has no clue what I was talking about. When he stopped in his tracks her eyes never left his sister as his face became hard and cold.

"You seem off is all I'm saying one minute you are being petty and angry with me the next you won't stop watching your sister. You know that she can take care of herself today made that abundantly clear."

I followed his gaze as I spoke as I watched Kai stop at a stop sign says she spun on her heels, her blond hair spinning around in gold curtains before she looked at me and then Kat. Her red gaze lit up with worry or joy as Katsuki held his hand up. After a minute she ran off leaving the two of us to our own device.

Suddenly this tension seemed to fill in the air as Katsuki jerked his head off to the side of the sidewalk was lush green grass. It looks so warm and inviting that I couldn't help but follow Katsuki as he dropped in the grass. Letting out a groan as he laid in the grass tucking his arms firmly under him till his finger was interlace holding his head as he stared up at the passing clouds.

"Sit we should talk about my sister why I didn't tell you anything about her." His voice softened with worry as his eyes scanned my face lazily. His red eyes no longer scanning my face while seething in silent rage. It seemed like there was something hidden behind his eyes as I sat down next to him.

Holding myself up with my arms as the warmth of the sunshine down on me the warm grass laid beneath me. This cute frown started to form on his face as he spoke in a cool foreboding voice.

"When we were 10 my mom go into this huge fight with my sister, kept saying that she was too pretty and talent to be such an idiot that being a hero is a waste. That, of course, sparked an argument even bigger than the one that they were already in. Anyway, it ended with Kai running out of the house…."

His voice grew cold and angry as his head lolled to the side until he was looking at me.I could feel the warmth of his gaze on my face as I turned to look at Katsuki. My gaze meeting his as the fiery rage started to form in his eyes. Whatever love or joy that might have started to in his gaze was gone.

"She left and at the time we were still training with our quirks she started to practice, to go out wherever her feet could take her and that was anywhere really. Well, this time around it took her to a den of villain. I chased after her I'm older it's my duty to watch her.

Well, I didn't get there in time, they had her pin against the wall, she was covered in blood. They sliced her up pretty good, they were going to rape her when I stepped in. I took them all on I came close to killing them when I grabbed Kai and ran out there.

After that, she decided that she wanted to go to school in America to leave and have to forget her troubles for a while. She blames our mother for all of it and I hate to say I really do because I love my mother but I think the same thing. Hence why I don't get along with her why I treat her the way that I do."

I hear his voice grow cold and deadly serious as I sighed heavily I could see why she looked like that in the bathroom. The way that she blinked back tears and seemed perfectly protective of Katsuki. He saved her for a fate worse than death. I look at Katsuki thinking for the first time that I might really be seeing him.

"So now you know but try not to bring it up, but that is why I didn't want to tell you about her just yet. I don't like new people around her but now I don't have a choice with her starting at the school."

I suck in a worried breath before he glared heavily at me like he was trying to figure something out. "So what did you to talk about? I don't want to pry but she's my sister and if you upset her I would like to know…"

I snarled angrily before sitting upright glaring heavily at him for a minute before standing up getting ready to storm away. "She invites me to dinner tonight and I was thinking about it but my boyfriend is an idiot." With that, I stormed off rage burning bright in my chest as my face turned bright red.
