The game follows a murder notice delivered through a Warabeuta song, with seven geniuses gathering at the scene. The developer packed in what they called orthodox mystery elements, including a modern locked room where surveillance cameras may be key, a classic locked room with locked doors, astrology, and a puzzle of flesh and blood.
Renka said they always wanted to try making a mystery with these elements. The developer has released five works by 2026, with three in May alone. The previous work, How Much Is the Corpse in the Stocker?, holds a Very Positive rating on Steam. Renka's official X account said visual novel production is something they always wanted to do, and that they carefully work on each title in their own way.
