Do everyone know that Nozomi like know that Honoka,Umi,and Kotori would create a group name Muse?

I guess...?? i mean she had her tarot cards...and besides if you look at some of the episodes carefully,especially where the 2nd year duo were up the roof (i forgot what episode is that,but its in s1),you would see the door ajar and someone was peeking through...with green eyes,while the three-if i remember right-were talking about idol stuff and i'm pretty sure its Nozomi. Plus, she's the one who named the group Muse...aaaand the first time that Honoka tried to make an idol group, they asked for permission from the Student Council, which,i remind you, Eri and Nozomi were a part of :P ...i think the real question here is...How was Nozomi so sure that there would be 9 people,that she should name them Muse and who those 9 are supposed to be? although,i think that too could easily be explained with her being able to "read into the future" or something with her tarot cards...

Yeah, the anime kind of tried to get that idea across, from point of view. I think when I first watched I didn't really think about it, I just watched and then was surprised when they named it Muse, but I watched it again and realised just how obvious they made it and kicked myself for not bothering to pay attention to the details.

"Her cards told her..."

I knew about them thanks to the "Love Live! School Festival" game c:
