During their final employment trial for a space corporation, cadets Izumi and John crash into the abandoned research vessel Todoroki—a ghost ship harboring "Mysterious Being X." Infected by its psychic parasite, they must scavenge three antidote injections across 12 hours while battling the serum’s erotic side effects. Every corridor holds carnal peril in this survival-horror visual novel.
Cosmic Horror & Erotic Degradation
1. The Todoroki’s Twisted Legacy: Explore a vessel frozen in time—decrypted logs reveal illegal bio-weapon trials. Environmental storytelling exposes containment breaches through mutated flora and holographic crew death screams.
2. Mysterious Being X’s Grip: Contact triggers psychic corrosion. Without injections, hallucinations manifest as psychosexual whispers. Each antidote dose intensifies Izumi’s libido while delaying transformation—a cruel trade-off.
3. Shared Corruption: John avoids infection but witnesses Izumi’s descent. His loyalty missions involve restraining her during serum-induced frenzies or exploiting her state for advantage.
Gameplay: Survival Through Sensuality
1. Resource Scavenging System:
◦ Antidote Synthesis: Combine chemical precursors in wrecked labs (e.g., stabilize serum with coolant to reduce lust penalties).
◦ Environmental Hazards: Navigate zero-gravity brothel decks where "pleasure drones" drain stamina.
2. Erotic Exploration Mechanics:
◦ Pose-Art H-Scenes: 80% of CGs use modular "body canvas" tech—customize Izumi’s proportions per scene (big breasts/butt sliders activate pregnancy content).
◦ Risk-Reward Triggers: Override door locks via minigames to access egg-laying chambers or avoid them to preserve sanity.
3. Consequence Web: Ignoring John’s warnings during Izumi’s lust spikes may impregnate her with Being X’s spawn—altering endings.
Content Design & Replayability
1. Fetish-Focused Artistry:
◦ Bodysuit Degradation: Damage systems reveal skin progressively during combat.
◦ Dynamic Belly Physics: Pregnancy/egg-laying scenes feature real-time inflation tech.
2. Narrative Branching:
◦ 18 Endings: Achieve "Pure Escape" (cure intact), "Hive Mother" (embrace corruption), or "Serum Addict" (overdose on lust suppressants).
◦ Hidden Routes: Sacrifice John to unlock Being X’s erotic hive-mind sequences.
3. Accessibility Tools:
◦ Hint Tome: In-game text decrypts scene triggers (e.g., "Combine reactor key with bio-scanner for breeding lab access").
◦ Lust Meter Toggles: Adjust side-effect severity for customized playthroughs.
