Renko Kamishakuji
Candidate for next term's Student Council Secretary. She may be small in stature, but she is a domineering, brazen, vainglorious mad scientist. Because of this fact, she is frequently seen wearing a white lab coat. She treats Kaoruko like a slave, and produces a variety of questionable inventions, such as the mecha used in episode 1. While annoyed at having to work as a team (not to mention the dispositions of her team members), Renko proves on many occasions to be an integral member of the group. She also loves Pandas. (Wkipedia)
