NTRaholic SS puts you in the role of Ryunosuke, a landlord whose newest tenants bring money troubles and a marriage he intends to disrupt. Newlyweds Chiho and Shota hesitate over the rent, so you propose that Chiho clean your room to cover the difference. That housekeeping arrangement becomes the starting point for a single-player adult simulation in which you divide your days between earning money, interacting with Chiho, and buying items that open further story developments.
Chiho and Shota have been together since university, and their bond withstands Ryunosuke’s initial advances. His response is to enlist Lilith, a succubus, and strike a pact to influence Chiho over 90 days. The premise gives the calendar a specific purpose: use that limited window to advance a corruption storyline through personal contact, purchases, and supernatural abilities.
Four Time Slots, Plenty of Bad Intentions
Every day is split into morning, afternoon, evening, and midnight. You can work part-time, spend time with Chiho, or buy items. Earning the money you need takes time away from other activities.
Minigames raise intimacy and advance the story within that 90-day limit.
The Succubus Has a Progression System
Lilith’s magic is part of how you progress. Her abilities let Ryunosuke influence Chiho from a distance, while an increasing Lust Mark value unlocks additional succubus abilities and gameplay mechanics. Accumulating corruption energy also opens more Devil Skills, which lead to further interactions and story developments.
Chiho's changing behavior, new interactions, and supernatural abilities form the main progression system.
A Shopping List With Ulterior Motives
Part-time earnings fund items that help move the story forward. The Spy Cam lets Ryunosuke observe the newlyweds’ room next door, extending his intrusion beyond Chiho’s housekeeping visits. Another purchase, the Ninja Scroll, unlocks special gameplay features.
Progression also expands the setting beyond the rental property. The night market, izakaya bar, and hot spring inn become available as Chiho’s corruption advances, while increasingly provocative selfies accompany her changing behavior. Locations, items, and messages all feed into the same adult storyline.
Content and Availability
