Power nullification is causality based

".........Sorry. I can not say anything as an excuse, but it's exactly what you said. If there is something that chose you, it's something that even we, the divine spirits are not aware of. But, there’s one thing that I can guarantee. You───just a human known as Sakamaki Izayoi, no matter what form, will always have the potential to save the world. This is not about the existence of your Gift. Even without that tremendous power, your, your own soul took that kind of form, and Sakamaki Izayoi was summoned for that reason."

The boy bound to be born to fight against the destroyer of the world, 「Absolute Evil」.

Among the various timelines, only Izayoi Sakamaki will become the trigger for saving the world. It might be a boy with another name, or perhaps even a girl.

Not a hero chosen by the gods, but a hero chosen by the human history to rescue the future of humanity.

All that is connected to his Gift.

"..........Haa, I see. In short, my Gift reverses cause and effect? Not a Gift that was gained by saving the past but a blessing from a promise to save the future"

"That's right. Truthfully, you should have been born a bit later. Because the formed [No Names] interfered with the human history, your date of birth undergone a big change. We created new Gods and tried to support the candidate, but...........Somehow with that interference, we hit upon the possibility called Sakamaki Izayoi."
