Saying it bypasses Acausality would be a stretch, especially since the reasoning behind Acausality is not explicitly stated but rooted in assumptions.
Hmmm... Well, I do think we need to elaborate on the stagnation and progression point, and on Orihime's powers which admittedly have been resisted before. There's also the fact that Tsukishima undid the Almighty's effect by changing the past.
This is more of an anti-feat than the opposite.
I'm actually still unclear on whether Ichibei is being considered to have the same Acausality here, since the OP doesn't list him but people are talking like he would be included.
The OP's reasoning doesn't strongly support his point, as with half of his arguments, can be easily interpreted differently than he narrated it to be.
I do agree that the creating of life and death is a seperate thing, leaving aside the issue of the underworld already existing which implies death also existed in some form already.
Before engaging in a full conversation about this, provide evidence that his existence exists independently or differently from the current time of the verse first. Otherwise, we would be arguing about a topic that lacks a backing in the first place. But that's false btw.
I don't think it is false, since other verses get given Acausality 4 for handling erratic time flows without being affected, although DMC I think has other things pointing to it as well. I'm not sure about plants in Trigun. Still, it's likely that the world of the living already had the same time flow and Reio only created the time flow of the Dangai, the only one that flows differently.
That doesn't really convey the difference in causality between back then and the present, and I don't see anything indicating that he created the progression and stagnation in the OP, lol. Can you please quote that specific part?
The OP talks about stagnation and progression being altered. I'm using a phone right now, so I can't go to a different page or even tab while typing or the dumb thing will refresh and erase everything I've written. I'll check in a moment, but the OP links to a strange location anyway.
Update: Okay, I just read the scan linked in the OP. Ichibei says there that life and death weren't happening and humans and hollows lived together in one world, until hollows started eating humans which would have eventually turned all the souls into one big Menos, which was described as a cause of the world stopping. The stagnation and progression reference in the scan simply seems to be referring to life and death, as stated: "there was no such thing as life or death, and without progress, there was no retreat".
Unless there's more solid proof of cause and effect being different, I'd have to say this isn't enough. What was that about the Reio's arms embodying stagnation and progression?
