I can't help but fear that the EVERYTHING IS AWESOME VICTORY LAP Fuuko's going through is going to hit a major bump in the road with Andy. Don't get me wrong, I do enjoy the victory lap and the whole groundhog day fixing the past thing, but there needs to be SOME cause for pathos going forward.
I want there to be a secret loop-hole, no pun intended, created by Luna. Or else maybe Sun is bored and/or Luna decides to explain to Fuuko that what she's doing is basically just Juiz on like... Loop 34, or something, and that it isn't going to go better. At. all. And that she's going to intervene and maybe convince Sun to try something "new" for the grand finale.
That, and I want Andy to be WORSE off than Victor and be like. . . "Yeah... if I work with Sun, I can die. And then it's all over. And sUfFeRiNg turned out harder than I thought. Maybe from sheer loneliness. Or something. Or he doesn't remember and Remember is stolen/lost/innefective has some kind of drawback. Dunno.
It's just... we already saw Ragnarok. I'd feel like the goal now would be to STOP Ragnarok, which should be theoretically possible.
There's also the fact we haven't seen the Negators unite with their antithesis. And it should be noted that the UMAs specifically refer to the Negators as "Vessel of ___" each respective negated force. Fuuko is "Vessel of Luck". Andy is "Vessel Death". Why are they not uniting with those as was done by Unremember and Ghost? I'd imagine that'd be powerful. Especially if they could perhaps tame the UMAs. We know Clothy is helping. And we know Spoil helped... So is it that difficult to get their cooperation? I feel like there's more here being left for potential new arcs.
So yeah, waiting for something to go wrong. I suppose the cliche and the pun will get selected and UnRuin is where it goes wrong. Fuuko's plan to save him will get "ruined."
