s2 fucking when
I need more Cyan and I wanna see more of the other bands, all the music in the game is amazing
Wait for relevant animu information in the Anime Japan 2016 open panel for March.
That's when they'll talk about the planned short series (probably in the style of those youtube shorts), and the second season.
For now, all we can do is wait.
Oh, and for those wondering about the announcement of SB69 season 2 in April.
That was unfortunately wrong.

You're right. That's a positive way to look at it.
Blackmail and doggystyle Retoree
She could come to visit MIDI City, or be summoned by Grateful King to Sound World because Dagger is doing some shenanigans.
My personal crack theory
however is that her sempais were really Chuchu, Retoree and Moa, who came from Sound Cosmos to the human dimension to visit Cyan, but arrived earlier than they left (because reasons we don't really need to sweat about) and then they decided to disguise themselves as normal girls in the school that Cyan would attend to and inspire her to want to join the local K-ON.
That's how I would handle it.
