Fumiya Shindouji

Fumiya's older brother was Ayumi's first boyfriend, but he died in a motorcycle accident. When Ayumi fell in love with Ryuji, Fumiya regarded it as a "betrayal" of his brother, and vowed to destroy them both. He gathered a gang and started beating up Shonan toughs, eventually leading Ryuji on a wild motorcycle chase. He crashed when a truck came the other way, but Ryuji saved him from falling over a cliff.

In Shonan 14 days he appears as the CEO of Tokyo Talent Productions. He helps Onizuka track down Miki Katsuragi and the other kidnapped girls.

In GTO: Paradise lost he now works in showbiz, as the president of Entertainment Agency Floyd. He is seen to be very familiar with the industry, even some of its underground dealings.
