Chapter 13 Sisters and Girlfriends Don't Mix

Katsuki POV

Even as I stalked down the hallway with nothing but the slapping of my and Kai's boots to keep me company I knew that everyone was waiting. With stupid shocked looks plastered all over there faces. Like it's all that shocking, you would have thought that it would be obvious.

We do look a lot alike even when Kirishima first saw her he knew that there was some kind of family connections. "Are they all this stupid" Kai voice lit up with intrigue as her cool red eyes looked me up and down expectantly. But all I could do is laugh because, to be honest, they all are that stupid.

She on other hand didn't think that it was so funny as she walks alongside me. Her steps weren't as light and confident as before. Her shoulders slump slightly as her hands shoved deep into what little clothing she had on. I mean really she left little to the imagination I mean our dad is a clothes designer. Why would he let her leave the house like that?

"Stop staring it's weirding me out" As I looked up from Kai bare legs I noticed a light pink blush filling her cheeks. Good, she should be embarrassed. "Put some damn clothes on, next time I see you in that stupid costume I'll rat you out to mom and dad."

I watched a cold shiver go down her spine at the mention of our mother. My voice is cold and deadly serious. I'm older than Kai by ten minutes. Making me her big brother and I will be damned if some chump is more focused on her ass. Rather than having her back because the moment she hurts or comes crying to me about one of them.I'm going to go postal and end up doing something stupid.

Here's a fun fact for you I was born at 11:59 meaning that I and Kai were technically born on different days. Which makes it all the more fun to play overbearing big brother. Though Kai hates it, I don't know why I think that I'm the best older brother ever.

"You wouldn't? Would you?" I looked up at the sound of a harsh yet curious voice. Kai's eyes were wide with worry and confusion as she stared me down. I'm sure that she wanted me to say no.

But that so isn't happening I don't know if it is the fact that all the guys in my class are peeved and fucking idiots. But the last thing I wanted was them giving my sister any kind of attention. I shifted to get a better look at her forcing both of us to stop short.

Taking in the small worry lines of her face. Or the way that her red eyes darken to a cold crimson color as I spoke. "If you don't wear something else I will rat you out. I don't like the way they look at you. There fucking scumbags and they only want one thing it's my job to protect you and I can't do that if I'm in jail for killing one of those pricks."

My voice turned cold and harsh as I thought back to Denki who kept asking me how I knew Kai. Or that little fuck with the grape-like hair that kept drooling over her. I wanted nothing more than to knock their lights that would just cause more harm than good.

So I just pushed the thought out of my mind as my hands began to smoke and crackled. As I walked down the hall I could hear the surprised voices from behind a great large steel door. Surprised squeak and low questions that they didn't dare to utter to me when we got face to face. But the only thing that I am worried about is Uraraka.

I hope that she isn't too pisted about me not telling her. I just wanted time for just the two of us. Before my family was forced upon her. They are just as bad as me if not more. My sister and mother are overly protective of me and it's unbearable at times. I'm pretty sure that my mother and my sister don't like Uraraka and they are a big part of my life so for them not to like her. Could be disastrous.

But I managed to put a brave face on as I came face to face with a large silver and blue steel looking door. Large and impending I knew that there was nothing to worry about at the present moment. Ochako wouldn't start a fight in the middle of the room though I'm sure at some point through the day she is going to force me to talk to her. About this about not telling her the whole truth which I'm sure is just going to cause another problem.

But I forced the door open as the squeals were reduced to dull whispers as the light from the hallway, flood the dark room. The bright blue screens from the computers illuminated the room slightly. Bright red and orange words that said Team Bakugou won. Were plaster across all of the screens as EH and All Might both stand there, shell shocked but amused looks on their face.

EH cunning red eyes looked over me and then passed my shoulder to where I'm sure Kai is standing. His red eyes seemed to utter a silent threat. You better behave or you two are going to get it later. So I did my best to push off the stares from the others. Kirishima is the only one who had this sly grin on his face as he walked over to me. Clasping me on the back as this huge goofy grin seemed to spread across his face.

This amused air surrounding him as his posture seemed light and airy as he grinned at me and then at Kai behind me. Even as I shifted I could feel her hands on my back as she peered her head over my shoulder.

Her blond hair shifting lightly over her face obscuring her visions. But as I looked around the room Denki and the grape fuck were practically eyes banging her while the girls all looked not Mina she just glared at Kai with rage and anger likes it's my sister fault that Kirishima has wondering eyes.

Then there was Uraraka, her deep chocolate brown orbs stared back at me, her face filled to the brim with shock but her eyes. They darkened in rage as a silent question began to pop up in her eyes. "How could you not tell me? I didn't really know how to respond to that but I don't think that I really wanted to. No matter what I said I'm sure that I am still going to be made out as the jerk.

"Alright then…" EH cleared his throat as All Might began to announce the next pairs but I simply moved off to the side with Kai coming with me. Kirishima was partnered with Mina and they were going up against Denki and Jiro. I already knew that it was going to win. But still, it would be a fun thing to watch. If only I got the chance.

The moment that I leaned against the wall Uraraka swarmed me a down on her face as both her hands were pressed firmly against her hips. I barely had time to cross my arms over my chest as she glared angrily at me.

Her brown eyes light up just a bit with outrage as the silent tension fell over the room. I knew that all eyes were on me so it's not like I could put a hand on her waist and tell her that I didn't mean to keep this a secret and that is just how it worked out. But we both knew that was a lie and that I purposely hid this from her.

"Was this what you and Mina were talking about in the closet." Uraraka's voice came out a cold venomous whisper as her eyes narrowed into two defined slits. Her body grew rigid as she ran her eyes over Kai who seemed uninterested by all of this. Her red eyes clouded over as she looked lost in thought maybe she was thinking about her new costume.

But I am more shocked that Uraraka managed to overhear my conversation in the broom closet. That couldn't be possible unless I looked up rather shocked and annoyed as anger began to burn in my veins. "Did you really eavesdrop on a private conversation." Uraraka's eyes widen in shock and rage as her face began to turn beet red. But for once it wasn't from embarrassment but for rage.

"You're really going to yell at me about secrets when you are the one that lied to me…." Her voice raises for a moment forcing all eyes on us again as Deku started the both of us down. His green eyes grew cold and luminous as he thought that we might be plotting to fuck him over again.

"I'm your girlfriend and you thought that you didn't need to tell me you have a sister. How am I supposed to get your mother to like me if you can't even trust me with the fact that you have a sister? I'm mean really are you an idiot."

Her voice began to rise again this time gaining the attention of Kai, who seemed to have this devilish grin on her face as she started to rise from the ground. A newfound purposes lit up her eyes with a malicious glint. God, what could she be planning now? She focused her eyes on Uraraka as they sparkled with new found interest. "So your the girl that can sway his angry moods" She giggled lightly like this is the best thing that could happen to her.

She watched as Uraraka looked at me her eyes narrowing even more if they were even possible before trying her attention to Kai. A dazzling smile taking over the once angry sneer as her entire body posture changed.

From angry to joyful in a matter of seconds as her bubbly personality came back as she spoke in a cool voice. "Yes I am and I wish that I could say that I have heard a lot about you but Katsuki likes to keep secret like our relationship so if you could keep it on the down low."

Kai's eyes seemed to glow at this news as she shifted from me to Uraraka, I could tell she was growing giddier with each passing moment, it's was like this gave her a new purpose. She looped her arm in Uraraka's as this sly grin formed on her face.

Her eyes seemed to darken as she begins to steer Uraraka to the door. "Let have a chat in the little girl's room shall me." Her coy voice forced a cold shudder to go down my spine as I watched my sister take my girlfriend hostage.

The door slammed with a final thud as they began to disappear and I found myself was swarmed with a new group of people. Denki's eyes glowed eagerly at grape fuck face came running over to me. Drool practically dripping from both corners of his mouth. I mean really did either one of them think that I am going to hook them up with my sister.
