Suda wrote the game's script in an improvisational manner, aiming for a lighthearted atmosphere that sometimes even mocked the game's design. The main reason for this was that he had fully immersed himself in the grim atmosphere of "The Silver Case", and he wanted a change both for himself and his next game. Returning staff from "The Silver Case" included scenario co-writer Masashi Ooka and character designer Takashi Miyamoto; the change to a lighter atmosphere proved difficult for Miyamoto when designing the characters. Despite the differing aesthetics, the overall visual design was deliberately similar to that of "The Silver Case". The music was composed by Masafumi Takada, who had previously worked on "The Silver Case"; and Shingo Yasumoto, who had worked on the "Twilight Syndrome" series. The soundtrack incorporated remixed and re-orchestrated versions of classical music. The idea of using classical music was suggested by Suda: he told the sound designers to create a score that sounded like lounge music, but some considered tracks could not be used due to licensing issues. Due to budgetary constraints, voice acting could not be included, with characters instead being given garbled vocals "that sounded like random foreign languages".
