別当・和泉 九郎・スカーレット

Kurou is a genius spy from the prestigious Bettou-Izumi-Scarlett family, and a go-at-my-own-pace kind of person. He wields knowledge, strength, and great political power. Kurou also deeply cares for his younger sister Shizuka and often worries about her. [Edited from a combination of Haeleth's post and Choux's review.]
