Ryuunosuke Akasaka stands as one of the most enigmatic residents of Sakurasou in 'The Pet Girl of Sakurasou.' Already a recognized genius in the programming industry while still in his second year of high school, he confines himself almost entirely to Room 102, relying on his custom-built AI assistant 'Maid' to handle all external interactions. Despite his severe gynophobia, icy demeanor, and characteristically sharp tongue, Ryuunosuke consistently delivers indispensable technical support whenever his housemates face their greatest challenges — revealing a quietly devoted side beneath his cold exterior.
