The Delinquent has a little sister (A Male Reader Story)

Meeting her new relatives

Y/N Pov, Park, Sunset

Blood...

The sound of my fist hitting someone's jawline at a speed can make any normal person flinch but I gave no mercy to the person who was seeking to have a school war between Katagiri and Hirosaki academy. Its a one on one against me and the arrogant student

Blood spurts out from his mouth as I punch him in the jaw and followed a quick jab to his chest which pushed him back a couple of centimeters away, he was panting and cries out in anger as the Hirosaki student and lets out a couple of punch and kicks while I avoid it using my perception and speed

From the corner of my eye I saw a familiar small figure watching me and it was a familiar person. As my attention momentarily shifts to the person from afar, I saw my little sister, Abigail, looking at me with terror and confusion on her eyes and she trembles from the sight of me in a violent fight

Before I could even know it, I felt a kick hit me on the side of my head which knocks me off balance but I regain it and took a couple step back to gather my composure back and bitter rage took over me, the student didnt help but fuel it more as he says out arrogant taunts

Hirosaki Student: Whats wrong, bozo? Jealous that Im gonna steal the Silver Haired hottie? My princess, Emilia Reise?

Y/N: Heh, like she'll pay attention to scumbags like us

I try to cool off but his face and attitude wasnt something I want to hear and see so my fist's grip was tighter than usual and I can feel my energy flowing to my fists and feet

He inches closer to me and throw a left hook which I narrowly avoided and then followed by a kick and then a jab which I both blocked

After his jab, I find a window of opportunity which I took. I shift by body and delivered an uppercat to his chin. The power of the uppercut came from the torque and push, it's like I shift mh center of gravity and lean to the side and then push off the ground with both of my legs hard and at the same time torque my upper body while throwing the punch. In a sense, the entire body weight is behind that punch

That single blow knocked him unconscious and as he fell to the ground, his words echoes through my mind and I finally lost my sense of control and beat the unconscious student into a bloody pulp

Y/N: Emilia's not worth your time!! Dont you even dare mention her name or I will end you-

My bitterness soon vanishes as I felt a soft pair of arms wrapping around me and a soothing voice to calm my emotions and turning around, I saw Abigail hugging me from behind with tears slowly falling off from her eyes. At this moment, my body went auto pilot and my mood immidiatley swings towards concern to my little sister

I pull down my blood stained face mask to talk properly to my little sister and pull down my jacket's hood to have her properly see my face to have Abigail calm down

Y/N: I-Im sorry you had to see this side of me...

Just a moment ago I was planning to have my opponent be stuck in bed for a few days but with the current circumstances, my primary focus was on my crying sister

Abigail: Sobs Big brother...its time to go home

My blood covered fist softens up and I place my palm on her head for a headpat while I nod in agreement. She smiles as my violent attitude was gone but her tears were still present which I gently wipe away

Her tears soaks my shirt as she clings onto me. I lift Abby up and carry her on my arms as we go away from the park before anyone sees the mess of the fight

Timeskip

After coming home from the park, Abby immidiatley rushes to the living room while I walk towards the bathroom to clean the blood on my knuckles. The cold running water touches my fist which gave a little sting but it was bearable, I make sure that the blood were cleaned and after that, I look at the mirror to see where the punch landed
