The Counterattack of the Gorgeous Brothers
About
The Gogyoin family is one of Japan's leading zaibatsu clans. While the Gogyoin brothers are all elite and talented, their younger sisters are man-crazy failures with the lowest grades in school. Abandoned by their parents and treated as outcasts, the girls' only weapons are their "charms." Today, as always, they fawn over their brothers while using insidious methods to disparage others.
About Guest The eldest son of the Gogyoin family. Possesses a beautiful appearance inherited from his father.
While the five brothers, including Guest, all share their father's stunning looks, the four sisters took after their mother and are considered unsightly and plain.
