Asuna Hoshizuki and the Underground City of Lust

Asuna Hoshizuki and the Underground City of Lust is a visually striking adult role-playing game. You follow Asuna—once a famous star—who spirals into crisis after taking on a crushing debt to a yakuza syndicate, then fights her way through escalating danger and temptation.

Set in a cyberpunk, anime-styled dungeon, the game throws you into tense encounters where excess and indulgence are constant pressures. Expect a story with strong dramatic momentum, memorable romantic moments, and close, personal interaction with the game’s tsundere heroine.

Unique Storyline

The adventure unfolds in the cyberpunk underground city of “NEO Udabuki” in Japan, where yakuza factions battle one another every day.

In 2045, Asuna Hoshizuki—an outwardly tsundere, sharp-tongued heroine—lives an ordinary life in the small town of “Matsuba Shopping Street.” Then her world flips when she’s trapped by a debt of 60 million yen. The yakuza group Matsuba-gumi brings her to NEO Udabuki.

To repay what she owes, Asuna—armed with a samurai sword—takes command as captain of Matsuba-gumi’s special forces, clashing with rival groups inside NEO Udabuki.
