Sega Sammy Holdings
The show was created by TMS Entertainment, the animation subsidiary of Sega Sammy Holdings. It was primarily influenced by other anime rather than work from the West, and was created for a Japanese audience. Yuji Naka, then the head of Sonic Team, filled in as executive producer, and Satoshi Hirayama designed all of the original characters, basing the designs on Yuji Uekawa's original concept.
