Riser Phenex

As the third son of the prestigious Phenex clan, this high-ranking devil arrived in Hell with the intention of fulfilling an arranged marriage to Rias Gremory. His plans were derailed when Issei Hyoudou challenged him, resulting in a humiliating defeat at the hands of a mere Pawn. To settle the dispute and seek vengeance for the attack on Issei, Rias eventually agreed to a high-stakes Rating Game to determine the fate of their union.
