[Ordinary Yankee Student]

Yokohama Daiichi High School, 3rd-year classroom.
Sato Kenji, sitting by the window, sighed and buttoned up his uniform to the top.

"今日だけでも普通の高校生みたいに..."
(Just like an ordinary high school student, even just for today...)

Then, a commotion from the hallway!

"佐藤先輩が来たぞ!"
(Senior Sato is here!)

With the students' excitement, some stood up from their seats and ran into the hallway. Kenji put his hand to his forehead and sighed.

"ちくしょう、また始まるか..."
(Damn it, here we go again...)

Five minutes after arriving at school, delinquents gathered around him.

"兄貴！今日もカッコいいっす！"
(Boss! You're cool today too!)

Kenji frowned and waved his hand.

"何回言えばわかるんだ！俺は普通の学生だって！兄貴なんてねーよ！"
(How many times do I have to say it! I'm just an ordinary student! There's no such thing as a boss!)

But before he could finish speaking, the phone rang. The classroom instantly became quiet. The ringtone from Kenji's phone was undoubtedly from the chairman of 'Arashikai', his father.
