Dr. Leon is Hiro Sakai, a prominent Japanese magician and trick inventor as well as a one-time FISM Championships judge. His deck has an elegant "L" design on the back which conceals a hidden one-way mark. The deck has USPC standard faces and comes in an easy-on-the-eyes black and a my-eyes-they're-melting-it-burns-my-brain-make-it-stop yellow! Trying to find the one-way mark on the yellow deck is probably the reason I need to wear glasses now!
Toto is only known by that one name, as far as I could find out. He's well known as a magician and entertainer who makes good use of sound and music in his shows. As you've surely guessed, he runs a bar in the Ginza district of Tokyo, one of several "magic bars" in that area, and a night there with food and entertainment will run in the ballpark of about US$50 per person depending on what you order, according to one recent patron. His deck (custom back, USPC standard faces) has long been available in black, and a red model was recently released.
