when you think about it, RAS in game doesn't make a lot of sense currently. we're following the anime timeline, and in that, they haven't even fully formed yet. I wouldn't say that it's guaranteed that they'll be added with 3rd anniv or whenever they officially get together, but that's probably the best bet.

but hey, they might just keep them as a mostly live band since it'd kinda throw off the whole "5 bands with 5 members" thing huh
