The Irregular Reincarnator differs from the typical reincarnator who is sent to different worlds, often referred to as being "isekai'd," through the intervention of a celestial deity or an unexplained phenomenon that transports individuals to a new existence as someone or something entirely different. An Irregular Reincarnator is a rare individual who, upon death, is chosen not by celestial gods but by deities from the omniversal realm itself.

Unlike conventional reincarnators who assume a new identity in a different world, Irregular Reincarnators retain their original form, even if their death occurred under tragic circumstances. While ordinary reincarnators must earn or acquire power in their new lives, Irregular Reincarnators are granted godly powers directly by the omniversal gods through a sacred ritual originating from the omniversal realm. This ritual marks the beginning of their new destiny before they are sent to another world.

An Irregular Reincarnator receives their powers only if they are deemed deceased in their original world, allowing them to keep their original body in the new world. Ultimately, as they navigate trials and challenges that define their journey across worlds—be it for good or bad—their powers evolve to transcendence, elevating them to the status of a pseudo-deity. Their final fate, whether to join the omniversal realm or remain apart, is determined by the omniversal king.

Xavier Salvador serves as an example of transcendence, having forged his own destiny through a campaign to establish his superpower state, which has the potential to evolve into a hyperpower, significantly altering the history of the world of Aifea through his ideologies. This journey has caused his godly powers to grow increasingly potent, positioning him as a potential pseudo-deity in the future.
