Story:

Aki Tomoya, a high school otaku, regrettably runs into his ideal girl one day only to discover that she is barely there. Tomoya now wants to make the girl into a heroine in the only world he is familiar with: 2D dating simulation games, thanks to his otaku passions. Eriri Spencer Sawamura, a half-foreign friend from their youth who possesses artistic talent, and Kasumigaoka Utaha, a well-known prodigy writer, serve as the illustrator and script writer, respectively, in order to achieve this goal. Oh, did we also mention the name of the dream girl?
