@koikun not really. There's more of the Tsukimizuki members and some completely different characters.
Of course, Rikai is always there, and I think Rei-kun makes another appearance, but that's it.
That said, I only read volume 1, so I don't really know what happens in the rest.
Edit: Never mind. Rei-kun is there, Rikai is definitely in focus, and Haruka appears too.
That's just from reading the synopses though.
