紫延 七水

A stoic yet refined girl who serves as both the discipline committee's leader and the student council vice president. She always carries her wooden sword around her waist, which has made some students afraid of her, when in reality Nanami is a surprisingly timid girl. She is actually the school's second biggest troublemaker, just after Miyu, and due to her inadept computering skills, she frequently manages to download all sorts of viruses on the student council room's computer.
