Good choice of scene.  I always liked Touga and
the kitty, but haven't seen any cels from that.

  Chiho Saito probably held up studio to get 
them, as Touga is her favorite character and that 
is one of his really nice human scenes.  (Just 
kidding about Chiho, as she was really nice but 
she does have a penchant for Touga cels)
