Kei's uncle and doctor of the local clinic. Minoru is something of a lecherous rogue, continually making wolfish comments regarding the attractiveness of passing women, even in the hearing of his wife, who often retaliates with a measured degree of force. He is openly quite jealous of Kei's relationship with Mizuho; he is more than a little perverted ,in the Japanese sense of the word, but often covers for and helps Kei and Mizuho out such as moving Kei's goods into the married couple's new quarters, purchasing a proper wedding ring for their private ceremony, and paying for an expensive hotel in Okinawa for their honeymoon.
