Zenki is one of Kyo's eight daitengu. At first glance, Zenki looks scary but he's actually easy going and funny. In volume two, Kyo tells Misao that Zenki is in love with his sister, but it's only because Kyo is jealous and doesn't want her to get close to him. This happens after Misao has Hoki pose in a picture with her as her boyfriend.
