Hello,

The correct term for Post Production cels is "Rilezu" and not
Relay.

The word comes from the dragon quest game "re-raise"
i.e. to come back to life.

The shop that sells the cels in Tokyo is Madoka Ltd the
their site can be found here.

I still need ot do do some work on this site.

Thanks

Stephen
