    Synopsis

    ■Story

    One day at the Occult Research Club…

    Kiyono Okuda, the club president, discovers an old parchment and, driven by curiosity, performs a ritual—but something unexpected happens.

    ■About the Game

    This is a transformation game where three characters gradually change in appearance, personality, and thoughts as their souls are corrupted.

    There are two routes: a transfur (bestial transformation) route and a state change (objectification) route, with 4 branching endings: Happy End, Mild Ending, Severe Ending, and Bad End.

    A total of 21 endings are available (Happy Ends have no route variations).

    The gameplay is simple—open treasure chests and progress. The game intentionally features strong luck-based mechanics to express how chance and fairness can be cruel.

    Secret commands (cheats) are included for those who want to avoid relying on luck or quickly view all endings. See the “Game Explanation and Strategy Hints” file included for details.

    ※Note: No flattening, spherification, or similar shape transformations are included.

    ■Specifications

    ・32 base character sprites + 730+ expression variations

    ・18 base event CGs + 24 variations

    ・100,000+ total characters of text

    Editorial Review

    Transformation and Occult Research Club positions itself within the niche but dedicated subgenre of corruption-focused transformation visual novels—works where character degradation is the narrative engine rather than a peripheral kink. This sits apart from lighter transformation fare by centering psychological and spiritual contamination alongside physical change, treating the occult premise as a genuine plot mechanism rather as window dressing.

    The distinctive architecture here is the dual-route system splitting between bestial transfur and objectification transformations, each with branching severity levels that genuinely alter characterization and personality rather than merely adjusting explicit content intensity. This structural choice—where a character’s fundamental nature shifts based on transformation type—suggests designers thinking carefully about how corruption manifests thematically. The inclusion of a luck-based treasure chest progression system is narratively deliberate too; the synopsis explicitly frames randomness as thematic commentary on cruel chance, which elevates what could be tedious busywork into intentional design philosophy. The 21 total endings across happy, mild, severe, and bad variations promise substantive replayability for collectors seeking completionism, though the inclusion of cheat commands signals developer awareness that pure RNG frustration has limits.

    Production values appear competent rather than exceptional based on available information—this is workmanlike VN construction optimized for content variety rather than technical showcase. The school occult club framing is familiar territory, but serves the serious tonal commitment the tags advertise; there’s no comedic safety net here.

    This appeals specifically to players who fetishize psychological transformation arcs and enjoy parsing how corruption rewrites character fundamentals, particularly those drawn to bestial or objectification content presented with narrative weight rather than detached scenario buffet construction.

    A transformation VN that commits to thematic coherence between mechanic and narrative: substantial enough for devotees of corruption content seeking intellectual scaffolding alongside explicit material.
