Yes! yes! yes!
Pro spin-off!

And it also confirmed what we long speculated.

Kokaji, Hayarin, Akado and now Risa are contemporaries. ^^
I'm actually curious about when this is taking place. It seems like the spin-off is one big reminiscence but the background shows the pros/coaches are having a getting together or something.
