Card battle erotic RPG with a strong sci-fi setting and a gradual corruption theme. You play as Romasha, a virgin elite officer in the defense organization “Highlander”. Serious, justice-driven, and admired as the “unreachable flower”, she lives in the futuristic upper city of Solitia.
Core Gameplay & Themes
Battles against “Trash” entities revolve around a card-based Jamming system. Each fight triggers progressive effects such as clothing data erasure, stripping variations, invasive full-body inspections (similar to high-tech capsules), and visible body changes, including breast enlargement, pubic hair growth, and lewd tattoos on the stomach. Daily sexual harassment events steadily erode Romasha’s morals, pushing her deeper into corruption.
The game features LIVE2D expressions in selected scenes, over 75 basic static CGs, and short story-style events that evolve over time—for example, an innocent ice-cream outing that gradually turns lewd. A brothel (風俗) segment lets Romasha satisfy customers and raise her popularity to 100%. The story traces her fall from a proud, untouched heroine to complete degradation in everyday life.
