Sinful Testament

Houston, 1925. A heroine from the future wakes inside the daughter of a murdered crime boss and discovers she is not there to heal, but to negotiate her freedom as “compensation” to the Devil’s Six. To survive, she must become a player—bargaining, maneuvering, gathering information, and deciding who can be trusted with her liberty and her vulnerability.

Her only edge is memories of the future. That knowledge can be a weapon or a reason to suspect she’s lying. Six dangerous men. Seven deadly sins. Criminal contracts, port streets, Houston’s Chinatown, and laws that leave no room for naivety. You can’t simply run away here; redemption or ruin hinges on every calculated bet.

Sinful Testament is a dark historical otome visual novel set in a Prohibition-era crime-noir. Weakness is sold, trust is bought, and mistakes are unforgiven. Every choice can set you on a path to redemption or drag you deeper into the fall. The atmosphere crackles with intrigue, blackmail, and psychological tension, where romance doesn’t erase danger.
