I am now conceding the point that Sekai is actually her name after getting called out like that (just @ me next time Selebus, sheesh), even though we are told very explicitly not to take everything at face value and then given an obvious metaphor, so of COURSE us overthinkers are gonna chase that. Digressing.
Now we have a complication with regards to her appearance in this update, however, because we have an established character who can wear anyone's face. I'm not suggesting it was ONLY Doppelganger Flower Girl, but at any point in time, it COULD be. And i'm going to need to go through this a couple more times before I'm comfortable saying definitively whether or not Doppelganger Flower Girl was posing as Sekai at any given point during this update.
Sekai has the same power the angels do, apparently. That could be fun.
I am very interested to see if this means that Makoto and Futaba can now see the Angels the same way Sana can now.
I think we're getting very close to the end of Chapter 3, and I'm going to be spending the two months before the next update going back through the game to take better notes (I say that, I always forget to actually take them). I definitely need to pore over the game to note whenever I think Doppelganger Flower Girl is posing as someone, been wanting to do that ever since we got that reveal.
