The title Inma Keiyaku Sex Succubers (淫魔契約セックスサキュバーズ) is a composite of several key Japanese and English concepts, instantly communicating the game's themes. The term is the Japanese word for "Succubus" — a demoness or monster that seduces men via sexual dreams, draining their energy or life force. "Keiyaku" (契約) translates to "contract" or "covenant," a binding agreement central to the story's premise. The phrase "Sex Succubers" is likely a stylistic rendering of "Sex Succubus," with the "ers" suffix adding a collective or playful twist to the theme.

The succubus requires spiritual energy (often manifested as sexual energy) to survive or maintain her physical form in the human world. In exchange, the human partner is granted heightened senses, supernatural charms, or simply the companionship of an extraordinarily beautiful entity.

The core relationship is defined by a formal or accidental between the protagonist and a human partner.
