Ren Mikihara is the Secretary of Jindai High's Student Council, a friend of Kaname and a daughter of a Yakuza boss. She is an example of Yamato Nadeshiko - Japanese ideal of femininity - and as such, she is beautiful, dependable and caring. She seems to have feelings for Atsunobu Hayashimizu, the Student Council's president. However, much about her is still unknown. Because women in the time of the Tokugawa shogunate were given names with two syllables only (usually adding the prefix "O-" to refer to someone of a higher social standing and considered a honorific), Kaname prefers to address her as "Oren-san."
