Popular female painters Suzuhira Hiroshi and Nishi Mata Aoi jointly serve as the game's original painting and character design; Tonosuke, a powerful scriptwriter who wrote the previous game, continues to lead the script; and the well-known musician Tsukasa Kikuchi produces the soundtrack. A luxurious cast of voice actors lend their voices to the heroines of this and previous games. The theme song "Fragile" is sung by the famous singer Migo Aki.
