Darren wakes up in a grim London orphanage in 1991, having transmigrated into the body of a boy just murdered by a bully. Before he can fully process his new reality in this magical world, a mechanical voice announces the arrival of the 'Saint Father System.' To survive and gain power, Darren must perform actions that appear selflessly holy and virtuous to others, earning points to purchase god-tier abilities like Occlumency and even a controllable Obscurus.

The catch? Darren is internally cynical, pragmatic, and far from a saint. He must constantly wear a mask of pure kindness while secretly manipulating situations, tripping bullies, and hoarding resources.

As he navigates the treacherous halls of Hogwarts and the shadows of the wizarding world, Darren walks a tightrope between maintaining his benevolent public persona and executing his ruthless survival strategies. With the Potter family's mysterious phoenix bloodline hinting at greater destinies, Darren must decide how far he will go to protect himself while pretending to save everyone else.
