Naoto Ooizumi is a seventeen-year-old high school student who serves as the secret scriptwriter for the fictional live-action superhero television series Cosprayers, a children's show. His involvement in the production is known only to the show's producer, Mitsuki Ikuta. To the rest of the cast and crew, he appears to be simply the camera operator for the behind-the-scenes making-of documentary, a cover he maintains to avoid the pressures of being publicly recognized as the writer. Naoto is characterized by his creative talent and a self-conscious, reserved nature. He develops a deep personal crush on Natsumi Yagami, one of the lead actresses on the show, and throughout the series he struggles to balance his professional responsibilities with his growing romantic feelings. His journey involves gaining the confidence to express his emotions and gradually transitioning from a shy observer behind the camera to a more assertive participant in his own life. He maintains a professional and romantic interest in Natsumi Yagami, while his secret identity is protected by the producer Mitsuki Ikuta, who acts as a mentor and gatekeeper. He also interacts frequently with the other actresses of the Cosprayers troupe, including Yoko Katsuragi and Hikaru Jougasaki, many of whom also develop romantic interest in him, creating a harem dynamic. Naoto's primary abilities are his skill as a scriptwriter and his practical work operating a camera for the production. His development focuses on overcoming his shyness and coming to terms with his role as a creator and as an active participant in his relationships.
