First Appearance: Volume 1
An 11th grade student and self-proclaimed best friend of Issei, Yuuto Kiba's got that "school prince" reputation down. He's best known for being the sole survivor of Project: Holy Sword, a traumatic experience that left him determined to hunt down everyone responsible. When Rias pulled him back from the brink of death, he became her servant, though his thirst for revenge never really went away. He's also got serious beef with Excalibur and everything it represents.
Kiba first showed up in Volume 1, dragging Issei to the Occult Research Club on Rias' orders. As her Knight, he's got ridiculous speed—the kind of god-level reflexes that make him nearly untouchable in combat. His swordsmanship is genuinely elite.
His Sacred Gear, Sword Birth, basically lets him summon an endless supply of demon swords whenever he needs them. He can pull out specialized blades like Holy Eraser or Flame Delete depending on the situation. Later on, he unlocked a Balance Breaker variant called Sword of Betrayer, which fuses demonic and holy swords together. He got it during a fight with Freed by merging his Sacred Gear with the spirits of his fallen comrades—which is as dark as it sounds.
