Gura has been talking quite a bit about her music in this member's stream. She confirmed that she really doesn't think she sounds good in produced music, and also doesn't like what producers do to her voice in released songs. She prefers how her voice sounds with just a mic - in karaokes for instance. Sounds like there are a couple of projects in the works, but she didn't sound particularly enthusiastic about any of them (besides the thing that's been in the works for 2 years, which she says is really important to her). I get the strong impression that she has no interest in new original music or solo covers going forward - she sounded kinda discouraged about the whole thing. She also said that Full Color might show up from time to time in lives, but not to expect anything more from it.
She also mentioned that instead of doing a promotional stream for the EDF game like IRyS and Kiara did, the devs let her make a "shitpost". She said it's the first time she's edited her own video in forever (since the Senzawa days probably, although she obviously didn't say that). She didn't say anything more specific about it, so I don't know if it's something in the game, or a promo thing that they haven't released yet.
She also clarified that she's "home" now, and looking forward to playing some games again. No mention of travel coming up, which with the concert in a week makes me think that she won't be there. I know that several of the talents (even those not participating in the world tour - Calli and Suisei for instance) are going to be in NYC, presumably for live MC segments and whatnot. Might be that not all of the girls are doing those, or some combination of live and pre-recorded MCs (please no more Connect the World awkwardness, Cover).
