The Senrigan Group is a powerful corporation that sponsors Aster Phoenix. The Group manufactured the "Destiny End Dragon" card for Aster. When the card was thought to be stolen, Aster's career was threatened, and he temporarily lost his career after losing a bet that Chazz Princeton would win against Jaden Yuki. However, when the Group later recovers the card, they agree to continue funding Aster.
The Group considers the Princeton Group (Manjoume Group in Japanese) their main rival company.
