My name is Matsuno Chinatsu, and I'm a second-year high school delinquent girl.
...A delinquent boy's older sister.
The Tokyo Manji Gang recently reached the top of Japan's delinquent rankings. One of its officers is my little brother. What's more, I'm close with the other officers too. Those idiots all call me "Big Sis" with the utmost respect whenever they see me.
Maybe they're so respectful because I've beaten them up before... I mean, I am pretty strong.
One day, I was just about to roll up my sleeves and teach a few delinquents a lesson in an alley when the man who appeared behind me gave me a fright.
"Hey, what kind of person picks on a girl?"
He had a volleyball tucked under his arm, broad shoulders and a narrow waist, with smooth, defined muscles. Even a plain short-sleeved shirt from the red volleyball team couldn't hide the masculine charm radiating from this incredibly handsome guy. He pulled me behind him.
"Hey, are you okay?" The handsome guy lowered his head slightly and glanced at me from the side.
...Yabai!
Why was my heart beating so fast? Why was my head starting to feel dizzy?
Almost instantly, I leaned weakly against his broad, solid, dependable body. "Sniff, sniff. Those delinquents were so scary! Handsome guy, save me! QAQ"
The delinquents across from us were stunned. "...Big Sis??!"
To find out if what I'd felt really was love at first sight, I decided to go to Osgu High and look for him. The handsome guy had a distinctive hairstyle, his uniform said "Nekoma," and he carried a volleyball, so he should be easy to find.
I was peeking into the volleyball club from the doorway when a hand suddenly landed on my shoulder.
He looked like he'd just finished exercising, full of energy and radiating endless charm.
"Hey, are you..."
Our eyes met.
He came toward me, radiating masculine allure with every step. Trying to stay calm, I held out my hand. "Hello, handsome guy. Thanks for saving me the other day. I'll probably be transferring to your school tomorrow, so I look forward to getting to know you."
"...Hey, maybe wipe the blood from your nose first!"
