Isabela

Isabela is a supporting character in High School DxD. She serves as one of Riser Phenex's Rooks in his peerage.

She is depicted as a voluptuous woman with short light brown hair (featuring three red highlights), grey eyes, and a distinctive plain white mask covering the right side of her face. Her typical outfit includes a black jacket with wide shoulders and leather straps, paired with jeans, fighting gloves, and boots suited for close combat.

Personality-wise, she's fiercely loyal to Riser and follows his orders without hesitation. Unlike some of his other servants, she shows respect and sportsmanship toward opponents who defeat her (such as acknowledging Issei after their fight).

She appears mainly during the Rating Game arc against Rias Gremory's team, where she's defeated after being affected by Issei's Dress Break and then finished off with his Dragon Shot. She has minor reappearances later in the series as well.
