Riko Izumi

Riko Izumi is a second-year student at CITY South High School and the younger sister of Kazuka Izumi. Her charming, attractive appearance has earned her widespread popularity among her peers, complete with a dedicated fan club of her own. Yet behind that pretty face lies an extreme love of sleep — she frequently dozes off during class, often waking up in a rather disheveled state. Beneath her seemingly carefree and airheaded exterior, however, she harbors astonishing hidden abilities, including hacking and bomb-making, which create a striking contrast that shines through in the chaotic everyday life of the city.
