Ero Scheme [v0.10.4 Pre-Alpha] [PassionScheme]

September 12, 2026F95

Welcome to Ero Scheme — a story-based, character-driven adult visual novel dating-sim!
Play as Ark (name changeable), a cynical strategist clawing his way back from ruin. Gather followers and challenge the deviously charming Lady Erostegia for the Throne.
Meet and recruit a cast of dangerously powerful (and irresistibly alluring) female allies—each with their own desires, secrets, and breaking points. Spend your days training, exploring the city, and choosing how to handle the people you draw into your orbit. Will you date them, corrupt them, earn their loyalty … or simply use them to further your own ends?
Your words matter. Your actions have consequences.
The choice is yours. As is the path you walk on, King.
