Now with his otaku passions, Tomoya wants to turn the girl into a heroine in the only realm he is familiar with: 2D dating simulation game. To accomplish this objective, he scouts Eriri Spencer Sawamura, his half-foreigner childhood friend equipped with artistic talent, as the illustrator, and Kasumigaoka Utaha, a famous prodigy writer, as the script writer.
