What do you mean waiting? This match is already over, and your points have been addressed, but simply not to your liking. This should have been closed already, and we are under no obligation to humor you any further. However, I will add one last thing so you get some sense of closure
It doesn't matter whether All Fiction could undo the bullets or restore the futures or not, because All Fiction won't. The futures where All Fiction would have tried to undo the bullets do not exist. All Fiction works retroactively, as you have said, and there is no way to stop the bullets unless you do it proactively. Weighted Words or Scar Dead would have been a better choice. Even if you claim that All Fiction could somehow make the bullet miss Medaka's heart, that doesn't matter. We know Medaka can survive normally with without a working heart due to her style
Another thing you have claimed quite a bit is that, because the futures existed at one point, they can be restored. Here is the thing, even if she can somehow "Unfire" the bullet, those futures don't come back. Ashen is a Perennial, and Perenials cannot leave The House, so the fight must take place there. Fate exists in The House, and time is cyclical. Those futures never existed as soon as that gun was shot. Unfire the gun, and Medaka still dies in that exact same moment; none of her abilities can save her unless she never fires the gun to begun with. All Fiction will not save her, no kind of causality manipulation will, because she will drop dead anyway even if it is not by the bullet. All fiction may be able to erase an erasure, but it cannot erase a retroactive and proactive erasure that stops the erasure from ever being erased
