Yuuto Kiba

Yuuto Kiba is one of the main male protagonists in High School DxD.

He is a third-year student at Kuoh Academy, widely regarded as the school's "pretty boy" or "prince" — extremely popular with female students (and often envied/hated by the guys) due to his handsome appearance, polite demeanor, and friendly personality.

He serves as Rias Gremory's Knight in her peerage (a reincarnated Devil with superhuman speed and swordsmanship skills), and he's the Vice-President of the Occult Research Club. Kiba is upbeat, chivalrous, loyal to his comrades, and takes great pride in his role as a knight, often acting as the calm and reliable "best friend" type alongside Issei Hyoudou.

His backstory involves tragic events from the Holy Sword Project in his human past, which fuels his growth and abilities with swords (including holy-demonic swords later on). Overall, he's portrayed as kind-hearted, honorable, and skilled in combat.
