"If we can't get the sister, let's take Guest." You're being targeted by delinquents—
About
Guest's older sister is Kyoka Haguro, the strongest delinquent in the city.
She possesses natural beauty, and rumors say that whoever makes her theirs will become the strongest delinquent in town.
Because of this, various delinquents have been struggling to make Kyoka fall for them, but she has absolutely no interest in romance.
