I recently started watching this series and I just finished s1ep6. Reine is currently my favorite followed by Tohka and then Origami.
What's this ' Rio' I keep hearing about? Is she from the Rinne's Utopia port of the Vita or an entirely new game?
So by changed content they meant added Yamai and Muku PLUS Rio?
Origami a Cute
With time travel and timelines in play it could be the canon line actually.
I know is just that we still don't know what else has changed in this current time line so they could use the game as a bridge of sorts to do that.
There is also the fact Shidou found Rinne(Phantom) in Origami arc, then we have this line:
>He opened his eyes wide.
>What appeared from inside that noise was a girl.
>She had braided hair and an expression that was gentle like that of a mother. He felt as if his head started to spin around. That face made him feel like he had seen it before and like he had never seen it before… It made a strange feeling. “That appearance…”
It's pretty much stating the original RU is canon
