Wait, did they just completely leave out from the manga adaptation the part where everyone dies and Sora rewinds time to beat the prophecy??? isn't that kind of really important to the plot??
Nonsense! It's just like Yu-Gi-Oh! If someone challenges you to play a children's card game, you play the children's card game. Doesn't matter if the world's falling apart around you, the card game comes before everything else
It's more likely that Keyaru deluded himself into believing that's what he's fighting for now. It's not that the author believes it, it's that he's telling you that's what Keyaru believes. I mean, didn't he write Keyaru's internal thoughts calling Keyaru out on this bullshit when he was fighting...
Dropping this hardcore after chapter 51. Fuck the mom and fuck the author for what she did with her. There's terrible writing and then there's comically horrible writing. This is the latter.
