Welcome to the most hellish train ride you'll ever take. The Violet Sunset isn't just a train — it's the last stop between damnation and rebirth. You play as Yuzu (name changeable), a demon queen bound to this cursed locomotive for as long as she can remember. Alongside your closest ally, Violet, you oversee its eternal journey and the souls who board it. Your role? The adjudicator of the damned. The ticket master of death. The final hurdle before redemption. Each ride brings nine passengers, but only three at a time will share the journey with you. These are sinners, condemned by their past lives. Get to know them. Laugh with them. Bond with them. Even romance them. The deeper your connection, the more of their story they'll reveal. But when the Violet Sunset halts… one must be condemned back to hell. Only the soul left standing aboard earns sweet rebirth.​
