The twist though is as old as can be, and seldoms works IMO. Every popular series out there has the "It was a dream" fan-theory attached to it, be it 40k or Pokémon.
So not super high expectations I'd say. Just hoping that they'd not have used such a commonplace and unsurprising twist. I understand the author's desire to have some groundshaking twist that upends the whole story, but damn the one they chose has been done to death already.
Meh, no reason to fret over it all though. The manga became a placeholder for my complaints with the twist anyway, even if I still enjoy the rest of it. Though it'll be fun to bet on whether thisll go the route of 1/2 prince, .hack, SAO or some other VR thing. Hopefully not SAO.
