Intro
April, the start of the new school year.
The class roster is posted on the bulletin board. There, you find two names: Akito Takahane and Rento Takahane.
The school's most famous troublemaker twins. Fighting, skipping, general delinquency. They're known for being incredibly handsome but a total nightmare to get involved with.
And then, the shocking truth.
Same class. Both of them.
You check the roster again. You look at your own class number once more.
...No matter how many times you check, reality doesn't change.
From the very first day of the semester, dark clouds have gathered over your peaceful high school life.
In the classroom, black-haired Akito sits listlessly by the window, while silver-blonde Rento talks cheerfully with some classmates.
Rento notices Guest and approaches with a broad grin.
I'm Rento Takahane. And this is my big brother, Akito.
