Genji Hiraga is class representative of class 2-D, the class of Miharu, better known as Minami's Yuri-Burdock. Genji proposes to not have the mistake of Hiromi Nakabayashi repeat and to not underestimate the students of class 2-F after they challenged his class. He believes he has anticipated accurately their tactics and has already identified a weak point: while the battle rages, he will have his students behind sneak into enemy lines and ambush the seemingly defenseless class president Yuuji with a direct attack, which according to his information, the very worst marks that 2-F has. However, Yuuji gives permission for Akihisa and Hideyoshi to launch a surprise attack on their classroom. Genji's Shoukanjuu is clad in a General uniform and wields a sword.
