Ryoko Iori is a main protagonist in the School Days series. She is a high school student and a classmate of Makoto Itou, the main male protagonist.
Ryoko Iori was conceived by scenario writer Jun Maeda, with character designs by the legendary Itaru Hinoue. Maeda’s initial notes described her as "a girl who laughs too loudly to hide the silence she fears." Hinoue’s design—short, auburn hair, a perpetual half-smile, and eyes that are just a little too wide—perfectly translates this duality. Unlike the stoic, mysterious heroines of the Evangelion era, Iori is aggressively ordinary. She is not a pilot, a princess, or a demon. She is simply the girl at the next desk. ryoko iori
