Cao Cao is the leader of the Hero Faction and the wielder of the strongest Longinus, the True Longinus. He is the descendant of the original Cao Cao recorded in the legend of the Three Kingdoms. Born in a village in a remote part of China to a household of traditional farmers, his life changed after awakening his Longinus following a life-threatening encounter with a monster. In the aftermath of people discovering his possession of the original Longinus and his parents trying to sell him to those people, he ran away from home and formed the Hero Faction to oppose supernatural beings. After his loss to Issei, his Longinus was temporarily confiscated by Sakra, and he was sent to the Realm of the Dead along with Georg and Leonardo. After returning, he reclaims possession of his Longinus from Sakra, subsequently becoming his vanguard, facilitated by the resignation of Sun Wukong.

Standard Equipment:

•Holy Spear of the Setting Sun: Cao Cao's Sacred Gear and one of the Holy Relics. It is one of eighteen Longinus, special Sacred Gears created by the God of the Bible that holds enough power to kill God's. Known as the Spear of Destiny, it is the original Longinus and the spear that pierced through Jesus Christ and contains his blood. It takes the form of a spear that can extend and retract according to his will and defend him from attacks, as well as create blasts of light and an energy blade. As it is one of the Holy Relics, it can take away the sanity of those that believe in God if they stare at it.

•Optional Equipment:

°Phoenix Tears: A small bottle containing the tears of the members of the House of Phoenix. These tears can be used to heal both minor and serious injuries, and can even be utilized to reattach lost limbs.

Intelligence: Cao Cao is very well versed in battle tactics as well as manipulation, much like his ancestor. He effectively deduces how the abilities of his opponents work and figures out their weaknesses, wasting no movements, neutralizing their attacks and accurately predicts their actions and fighting style shortly into a fight, allowing him to dictate and manipulate the battle.

Weakness: Truth Idea will not work if God chooses the will and dream of his opponent over his, such as against Issei.

Notable Attacks and Techniques:

•Heavenly Ring Holy King's Spear Enveloped in Brightness Which Brings the Polar Night: Cao Cao's sub-species Balance Breaker. It creates seven floating, bowling ball-sized orbs called the Seven Treasures, each with their own ability. However, they all have the exact same appearance, making it difficult to anticipate which ability is going to be utilized. He can also an Abyss  Side variant which restricts the use of the Seven Treasures, in return for a significant power up of the spear itself.

°Elephant Treasure: It grants Cao Cao the ability to fly and levitate any object or person the sphere touches.

°Female Treasure: It completely seals the special and unique abilities of women temporarily. It can only be canceled out by those with a certain level of strength.

°Pearl Treasure: It has the ability to release any attack sent towards Cao Cao to another target, creating a spiral that sucks in the attack with the spiral reappearing at another point and releasing the attack there.

°Horse Treasure: It has the ability to teleport a person of the wielder's choosing. Cao Cao can also apply this ability to himself.

°Wheel Treasure: It has the ability to instantly destroy all weapons, with the exception of significantly strong opponents.

°Householder Treasure: It creates several humanoid soldiers. Cao Cao can utilize them as a shield to defend against attacks. It can also create phantoms of Cao Cao, which he uses to confuse and distract opponents.

°General Treasure: It focuses heavily on destructive power and seems to have some sort of restriction on how often it can be used.

•Brightness of Supremacy: Connected to the will of the God of the Bible, it creates many effects and miracles. The will of God absorbs the wielder's ambition, and by responding to the strength of the opponent, miracles and effects to varying degrees are created. It can be the form of an blessing to capture and captivate their hearts, or grant the wielder absolute power to destroy the opponent.

•Medusa Eye: It allows him to turn anything he gazes at into stone.

Note: Cao Cao does not make use of Medusa's Eye after the events of Volume 12.
