One-Sided Sin: Premature & Permanent

Season One of One-Sided Sin: Premature & Permanent follows Reiji Hayashi, known as Retro, in a fractured timeline where reckless government decisions have led to extreme inflation, corruption, and the quiet collapse of public trust. As society deteriorates under its own moral failures, an all-knowing deity known as the Hand of Morality intervenes, delivering divine punishment through a phenomenon called Sin Combustion, where one's sins manifest as destructive force. Alongside this judgment emerge Virtues, powers believed to reward righteousness and restore balance. However, virtues are not simple blessings. They are tools, designed to measure, control, and reshape humanity itself. As the world restructures around moral power and survival becomes tied to perceived worth, Retro is forced to confront the true nature of virtue, punishment, and what it means to remain human in a system built to quantify the soul.
