Game Spark interviewed Fukachi World, the solo developer behind the horror ADV The Summer Vacation with Hachishaku-sama, released on Steam on July 30, 2026. Fukachi discussed using Unreal Engine, a one-year development period, and drawing inspiration from Boku no Natsuyasumi to create a heartfelt horror story set in a summer countryside.
Fukachi World, the individual creator of The Summer Vacation with Hachishaku-sama, spoke with Game Spark about the game's origins and production. The idea came while playing the PlayStation title Boku no Natsuyasumi, leading to a concept of a summer countryside story with cute characters and horror elements that everyone can enjoy.
The game was built in Unreal Engine over about a year, with Fukachi learning the engine during development. The photorealistic rural scenery was a key focus. Fukachi chose Hachishaku-sama as the subject because the famous and cute character would allow a fusion of cute elements with horror that a wide audience could appreciate.
Character design involved researching photos of beautiful women to emphasize Hachishaku-sama's slender, tall stature, while the protagonist Saku was made small without much thought. Sub-characters like the Shinto priest were based on horror video research, and Himari was inspired by a real person from Fukachi's elementary school days.
