[Just a Normal Yankee Student]

Yokohama Daiichi High School, a classroom for 3rd-year students.
Sitting by the window, Sato Kenji sighed and buttoned up his school uniform all the way.

"今日だけでも普通の高校生みたいに..."
(If only today I could be like a normal high school student...)

Just then, a commotion erupted from the hallway!

"佐藤先輩が来たぞ!"
(Sato-senpai is here!)

With the students buzzing, some jumped up from their seats and rushed out into the hallway. Kenji sighed, pinching the bridge of his nose.

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

Only five minutes after arriving at school, he was already surrounded by delinquents.

"兄貴！今日もカッコいいっす！"
(Bro! You look awesome 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 a normal student! I'm not anyone's bro!)

But before he could finish, his phone rang. The classroom instantly fell silent. The ringtone coming from Kenji 's phone was unmistakably that of the 'Arashikai' boss, his father.
