Miki Saotome (早乙女 ミキ Saotome Miki) is a cold young girl who is the polar opposite of Honey, being introverted and anti-social. Like Honey, she has the Honey System installed in her body, changing her into a blue armored form called Sister Miki (シスターミキ Shisutā Miki). In this form she cannot control her aggression, causing her to develop a fear of herself. She stays away from other people because she is afraid of hurting them against her will. Despite her cold demeanor, she cares about Honey.
