Yuuto Kiba

Once a human survivor of the tragic "Project: Holy Sword," this mid-class devil serves as a loyal knight within Rias Gremory's peerage. Known as the school's charming prince and Issei's self-proclaimed best friend, he wields the powerful Sword Birth Sacred Gear. Despite his newfound life, he remains driven by a thirst for vengeance against those who experimented on him and a deep-seated resentment toward the legendary Excalibur.
