"Forgive me. It is my fault that our world became the target of a Divine World. I am ignorant that it will cause the destruction of our world."
In contrast to what this digital entity did, I lowered my head towards him.
There's nothing wrong with being this shameless, he's already dead and the past would remain as the past. There's no such thing as going back to the past.
Time can only be perceived slowly. Just like what is happening inside that Dimensional Passage. Time can also be perceived in an accelerated state. Just like Raiden's Ability or any other abilities related to it. Yuko's Foresight and the principal's Clairvoyance could also be one application of it. However, it was peeking through one or more from the infinite possibilities ahead of time.
But no one can go back in time.
Like they said. Time is relative. No one or nothing can actually make it stop or go back.
