Kouji Fujiyoshi (藤吉 晃二, Fujiyoshi Kōji) is a student of the Holy Forest Academy and attends class 3-4.
DOB: June 1
Kouji is part of Kunio Murai's gang, usually tagging along with him and Tadaaki Kusano.
He initially tries to kick out Onizuka like everyone else but then instead becomes his friend, supporting him when he lost the money for the class trip.
He was an unwitting part of Miyabi Aizawa and Tadashi Sakurai's plan to get rid of Eikichi Onizuka, by making him collect money for the annual school trip and then lose it. The money was planted into Onizuka's jacket, which he quickly spent in one night, thus leading to Onizuka being charged with embezzlement. Feeling responsible because he had also stolen some of the money to buy a new watch, Fujiyoshi dropped out temporarily and worked to earn the money back, and his actions helped lead to a school trip to Okinawa, courtesy of Onizuka. He is also romantically interested in Miyabi, to the point of hijacking a car to get her to take a ride with him.
In the Japanese version he is voiced by Junichi Suwabe but in the English version, he is voiced by Steven Jay Blum, who also voices Eikichi Onizuka. In the dub, he has a surfer dude accent.
