Vali Lucifer is one of the main male protagonists of the light novel and anime series High School DxD. He is the descendant of the original Lucifer and a half-human, half-devil hybrid, granting him incredible demonic power and the Longinus Sacred Gear Divine Dividing, which holds the Vanishing Dragon Albion.

As the White Dragon Emperor, Vali leads his team, originally affiliated with the Khaos Brigade, before joining Issei Hyoudou's DxD alliance. He is Issei's chief rival, wielding the polar opposite power that divides and weakens opponents.

Personality & Appearance

Vali is a handsome young man with hazel eyes (light blue in the anime) and light silver hair (dark silver in seasons 2-3). His casual attire consists of a dark green V-neck shirt, a high-collared black leather jacket, burgundy jeans with a silver chain, black leather chaps with three bands on his right calf, and buckled black shoes. As a Devil, Vali has eight black bat-like wings on his back.

Initially portraying a cold, arrogant, and ruthless personality, Vali displays a calmer, caring side deeply attached to his comrades. His overconfident, battle-obsessed nature stems from a mix of Lucifer's pride and the trauma of his unhappy childhood. In his various dragon armor forms, he takes on the appearance of a white-armored dragon warrior. His most powerful form is the Diabolos Dragon Lucifer form, which gives him black and silver organic-style armor with 12 Lucifer devil wings.

Though prideful of his Lucifer lineage, Vali is more humble than other Satan descendants, understanding his limits. He respects worthy opponents like Issei, whose happiness with family and friends Vali secretly envies from his loneliness.

Despite a brutal upbringing, Vali retains a compassionate side, saving Asia's life and even protecting his abusive parents out of residual love. As he interacts with Issei's group, Vali becomes more open and lighthearted while maintaining his battle-maniac habits and obsession with ramen noodles.
