Not an expert on that but apparently it's a part of the Nipponese one, if nothing else.
Looks like SEGA had commissioned none other than Kishibe to design that character from scratch. Looks like that the anon who sang odes to the Japanese having good upwards mobility and pipelines in place for artists to score contracts with large companies, has a point there. Too bad that the game itself apparats to be yet another generic rhythm arcade and the busty doggo only appears once: https://www.youtube.com/watch?v=_uSQ-k5vKtQ
Well, 3 times, but simultaneously for some reason.
