Нана Хируко

Described as the "Lolita Computer." She looks just like Megumi Akino and because of this, was used as a spy by Abidani to spy on Tomu's team, and sabotage it from the inside by poisoning Yuko. She specializes in disguises and mental arithmetic, along with Abidani describing her as "a little demon who uses her lovely form and her clear mind as weapons to bewilder men", which she used for her business in cosplay dating, learning everything from personality to small quirks for her clients. No one even knew she attending the school since she focused completely on her business then attend classes. After she wins she hopes to take Natsumi with her after graduating and use her as a bargaining token to increase her prostitution business focused towards Lolicons. She likes to dress in a Loli-Gothic fashion. However it is revealed she has no confidence in her ability when the numbers exceed five digits, which is why she relied on taunting and poising Yuka. Despite her cruel personality, she has shown to be terrified at the thought of returning to the Abidani Seminar.
