Yuuka Koyama (小山 友香 Koyama Yūka) is a minor character in the Baka to Test to Shoukanjuu series. She is Class 2-C's Representative at Fumizuki Academy. In her debut appearance, she is revealed to be going out with Kyouji Nemoto, but when she sees him cross-dressing, she immediately dumps him.

In Episode 2 of the Matsuri OVA, the two have once again teamed up, only for her to find out during the battle that Kyouji has a cross-dressing album in addition to his previous cross-dressing attempt, resulting in their breakup. Nemoto's album was burned by Yūka in the Bonfire dance.

In volume 8, Yūka makes a reappearance, asking what Class F's plans are for the ST-wars. After a smart exchange between Yūka and Yuuji, she returns again later in order to declare a war against Class 2-F.

During the first day of the war, Yūka commands her class to fight the unorganized students of class F, who were fighting among themselves. Despite this obvious advantage, class F manages to reorganize its troops and fends class C off until the next day.

In volume 9, the war continues and class C starts off with the obvious advantage. She fights Akihisa who was late for school and is almost severely injured, only to be saved by her senpai pulling her out of the fight. She then sends class C troops to go and find Akihisa. Counseling her senpai, Yuka tries to work together with Nemoto and class B in order to win. However, all her plans are foiled by Akihisa who avoids all of the class C members that were sent to defeat him. Finally, she is defeated on the rooftop and her class is forced to take class F's equipment. It later turns out that Takashiro came up with her strategy for the war.

In volume 11, she admit that she likes Yuuji and it makes Kyoji frustrated. However, Yuuji dislikes Yūka for what has she done to her dumped boyfriend.[1]

Her Shoukanjuu wears a kimono and a skirt and wields a trident.
