Japanese pesticide and hygiene product manufacturer Earth Corporation recently unveiled Gokigen Lovely Days, a free browser-based otome visual novel commemorating Insect Repellent Awareness Day on June 3 (June 4 in Japan). Played from a first-person perspective, the game invites players to romance four seemingly ordinary attractive men who secretly possess insectoid traits. Notably, all four characters are voiced by Yuki Kaji, the acclaimed voice actor behind Eren Yeager in Attack on Titan and Shoto Todoroki in My Hero Academia.
As the heroine wanders through a solitary night, she encounters Kuro, the “prince on a white horse,” Chaba, the charming bespectacled younger brother type, Yamato, the sophisticated Japanese gentleman, and Wamon, the dependable, beer-loving big brother type. For those unfamiliar with Japanese, the names of these four characters bear a striking resemblance to various cockroach species – kuro-gokiburi (smokybrown cockroach), chabane-gokiburi (German cockroach), yamato-gokiburi (Japanese cockroach), and wamon-gokiburi (American cockroach).
The gameplay incorporates an “affinity” system. To achieve the optimal outcome, players must carefully observe the characters’ behaviors, which, by coincidence, mirror the habits and ecology of insects. Depending on the choices made, the branching narrative will lead to multiple possible endings, revealing the love interests’ “true intentions,” whatever those may entail.
This project serves as a promotional tool for Earth Pharmaceutical’s Gokisshu Su Sugoi! cockroach-repelling spray, and also includes practical advice on how to combat these pests.
Gokigen Lovely Days is accessible for free via browser, supporting both PC and Mobile platforms. The game is exclusively in Japanese and will be available through the official website until September 3, 2026.
