The chairman of Dankaisan's student council, and the only son of a police superintendent, Ran was initially displeased at Akira's pursuit of Mizuki. However, he seems to have developed feelings for Mizuki, and tries to hide it under the pretext of obtaining another "princess", the first "princess" being Akira. Unlike Rui, he is less easily swayed by Akira. Mizuki calls him "four-eyes", because of his glasses.
