The Vice President Is a Prince?! Aoi & Her Fun Companions

Yukimura’s little sister Ruri loves playing make-believe princess but refuse to acknowledge her brother which, to her, is not her ideal image of a prince. But when she meets the "prince-like" Usui, Yukimura manages to get Usui to go on a date with his sister in order to gain her favor. Things go on as hoped (complete with a costume for Usui made by Aoi) but, fearing the "princelier" Usui may replace Yukimura as Ruri’s big brother, Kanou and Misaki tries to break them up by either scaring them or even acting as a third party. However, Ruri sees through the ruse and runs away into a café, almost causing a cupboard to fall on her. Usui stops the cupboard and its contents from falling while Yukimura shields her. Yukimura scolds Ruri when her prideful behavior goes too far, and she apologizes and reaccepts her big brother. Sometime later, Kanou and Yukimura saves Aoi from a group of thugs, but does not recognize him as he is cross-dressing. Aoi decides to enlist them and, later, the Three Idiots to film a PV. Aoi enjoys the crew’s enthusiasm, but tries to deny it when they see Aoi genuinely smile. Suddenly an escaping thief bumps into Aoi, who then drops the camera’s memory card. While Aoi tries to catch it from the hill and nearly falls off doing so, Misaki saves 'her', who was chasing after the thief. Despite Aoi's abuses, the crew enjoyed working with 'her', and help find the memory card, which landed on Usui while he was resting on a bench below by chance.
