Debt Collector

When Dolores Constantine broke the ultimate taboo of life and death, bringing the dead back to life and avoiding her own death entirely, the "Debt Collector" manifested. To drag what should have remained dead back to the afterlife, the Debt Collector mercilessly hunted down the lives of Dolores and her machinations. Though the Constantine family managed to dodge fate once, they were unable to do so again. In the end, the Debt Collector drove the bygone Constantine family straight into ruin.

The Debt Collector is the embodiment of a Rule Anomaly with a single, crystal‑clear purpose: erase any consequences caused by those attempting to defy the natural order. In every case recorded, the Debt Collector's appearance is closely linked to the last matriarch of the Constantine family—Dolores Constantine. After Dolores used her Esper Ability to transfer the embers of her remaining life into a puppet, her drained lifespan should've ended then and there.

But the Anomaly she held, "Eternal Present," shielded her life. That perverse act—the reversal of life and death, the theft of time—triggered the manifestation of the Debt Collector, which went on to relentlessly pursue the Constantine family. It's believed that the Debt Collector's ongoing attacks on its "Debtors" are its way of forcing the world back into its proper, natural timeline.

The Debt Collector itself appears as a humanoid figure wrapped in a dark cloak, with one hand replaced by a large glaive, and the other substituted with a heavy chain. Only the "Debtor" themselves, along with other Espers, can perceive the Debt Collector. It manifests at the same time every day to attack its Debtor. These attacks are usually not physical, but instead, metaphysical.

That isn't to say it cannot also cause serious physical harm—if anyone interferes with the Debt Collector's collection process, it will utilize the blade and chains it is equipped with till the very end. Once suffering sufficient damage, or its given attack window closes, the Debt Collector temporarily vanishes. Current theory suggests that only by fulfilling its "Rule" and fully clearing any outstanding debt can the Debt Collector finally be nullified.
