Mai's beat spurred Rei on, and she kept up the whirling, energetic performance for another few bars before the tune shifts and she nods to Mai.

Stepping clear, she gets ready for Mai's second portion, and the inevitable duet where she cuts in halfway through. Her fingers dance, the audience treated to a genuine smile as she gets ready, coming out of the wilder tune and lapsing into a more peaceful one to harmonize with Mai's second bit.
