Double posting because I can but WHAT
The fundamental idea of the movie was thought of during Osaka's beatnation summit when I was dancing with a fan to Setsugekka - it was extraordinarily popular then so this time we've used a fan.
SO WHY DID THEY NOT FILM IN OSAKA?! Dai actually made it to the Osaka beatnation summit! They only filmed the Tokyo venue of Club Citta.

I wish there were footage of Dai dancing to Setsugekka with a fan, seriously.
This does make me think that Dai has a dance for a fair amount of Ryu* songs. But zomg, Setsugekka.
