Cao Cao

Cao Cao is a major character in High School DxD, specifically a prominent antagonist during the Hero Faction arc (featured heavily in Season 4, High School DxD Hero).

He is the charismatic leader of the Hero Faction (part of the Khaos Brigade) and a direct descendant of the historical Chinese warlord Cao Cao from the Three Kingdoms era. Cao Cao is widely regarded as the strongest human in the series, wielding the ultimate Longinus Sacred Gear: the True Longinus, a holy spear capable of slaying gods and dragons.

Appearance: He is a handsome young man with short black hair, sharp blue eyes, and a stylish mix of a Japanese school uniform (gakuran) and traditional Chinese hanfu attire.

Personality: Calm, confident, highly intelligent, and manipulative, Cao Cao is a brilliant tactician who inspires fierce loyalty in his followers. He believes supernatural beings like devils, fallen angels, and dragons threaten humanity, so he fights to protect and elevate humans above them.

He's a formidable opponent with immense speed, combat skill, and strategic genius, making him one of the most dangerous threats the protagonists face.
