Sakyubasu no Keishōsha: Derira no In'yoku Bōken

サキュバスの継承者:デリラの淫欲冒険 is an R18 doujin game from circle Ramen Cat Studio. This guide romanizes its title as “Sakyubasu no Keishōsha: Derira no In’yoku Bōken” (a Hepburn romanization of the original Japanese title, not a translation).

What this work is

According to the DLsite listing, this is a pixel-art, Metroidvania-style action game set in a fantasy world where humans and a demon race are at odds; the story picks up amid the chaos after a hero has defeated the demon king. The player takes the role of a succubus who uses a “seduction ability” to interact with enemies, casting arousal magic on them and draining their life force to strengthen her own abilities. Play involves exploring a large connected map, fighting, and solving puzzles while searching for the missing demon king. The listing also notes that some background art was produced with AI assistance.

Why it may work for non-Japanese readers

Movement and combat in an action-format Metroidvania are largely visual and control-driven, which can lower the amount of reading needed from moment to moment. That said, the listing’s own description mentions exploration and puzzle-solving alongside combat, and Metroidvania-style games often gate progress behind item descriptions, ability text, or environmental hints — any of which could carry more text dependency than pure combat does. The listing names English as a supported language, alongside Japanese, Chinese (Simplified), Chinese (Traditional), and Korean.

Language support

DLsite’s own “対応言語” (supported languages) field for this listing lists Japanese, English, Chinese (Simplified), Chinese (Traditional), and Korean. The listing does not specify what exactly is covered — menus, item and ability text, puzzle hints, or full narrative dialogue — and that has not been checked hands-on.

English-Friendly Score

3 / 5 — provisional, based only on the public listing page, not on hands-on play.

Score reasoning

• DLsite explicitly lists English as a supported language for this work
• Core movement and combat are visual and control-driven, which lowers pure-language dependency during play
• The listing describes exploration and puzzle-solving alongside combat, which is the kind of narrative/system-driven design where English coverage breadth is harder to verify from the listing alone
• No hands-on confirmation of how complete or consistent the English text is across the game

What remains unverified

• How much of the game is actually in English versus Japanese-only (menus and item text vs. full narrative and puzzle hints)
• Whether puzzle-solving sections depend on reading comprehension beyond simple UI navigation
• Overall translation quality and completeness, since this is an unverified listing-only signal rather than a hands-on check
