Cao Cao is the leader of the Hero Faction of the Khaos Brigade. He is the wielder of the Ultimate Longinus, the True Longinus. He is also the descendant of Cao Cao from the Three Kingdoms era. In Volume 17, Cao Cao becomes Indra's vanguard after Sun Wukong stepped down from his position.
Cao Cao is a handsome young man with short black hair and blue eyes. He wears a combination of a Japanese school uniform (more specifically, the gakuran worn by Japanese schoolboys in the fall) and ancient Chinese attire. He also lost his right eye while escaping from the Kyoto incident but later gained one of Medusa's eyes, restoring his sight. After his battle with Issei Hyoudou in Volume 12, he lost his Medusa's eye and since Volume 18, wears an eyepatch. His height is [177 cm] and body weight is [71 kg].
Cao Cao is a charismatic and manipulative person, as he was able to convince many Sacred Gear users to join the Hero Faction either from their own will or by brainwashing them. He also believes that it is his responsibility as a descendant of a hero to destroy beings like Devils, Fallen Angels, and Dragons which he believes are threats to human beings. Like his ancestor, he has the eyes to find people with good potential and considers them valuable talents. However, Cao Cao only accepts Humans with Sacred Gears in the Hero Faction and wants to see how far his faction can go against supernatural existences as he wants to test the limits of what humans are capable of. He is also cocky and arrogant, as he claims that he alone is enough to fight a god, and mocks opponents who are weak enough like Ladon, he tends to lose his control and composure when he is injured by someone unexpectedly or been caught by unexpected unluckiness and things, as is seen when he gets infuriated when Issei hits his eye, and nearly lose his composure and self-control. Sun Wukong and Vasco still consider his views and abilities are far amateur, childish, lacking and still have some developments.
His cockiness would be his greatest downfall, according to Vali, as he refuses to kill both Issei and Vali, and put his objectives first rather than them at that time. But still have some respects to those he deems he gets his interest and he considers strong, such as Issei, Azazel, Vali, and Vasco. Like Georg, he tends to overthink things if some things do not tend to happen, the way he expects to be, as is seen when he over thinks Issei's survival by the help of Great Red and Ophis. He also believes in fate, where he believes that there is a reason why he met Issei, Vali, and other various strong people that exist. It extended to the point that he mentioned in Volume 18, the reason why he returned is that he wants to know why the True Longinus was given to him and why it choose him despite his past mistakes.
During his return in Volume 18, he is shown willing to cooperates with the DxD against Qlippoth and during the Evil Dragon war, where he is shown helping various people including the last stand against Trihexa and the Evil Dragons as Indra's order, and align himself with the Grigori as it's agent along with Tobio.
Cao Cao was born in a remote village in a mountain in China to a traditional family of farmers. One day after getting lost in the mountain while playing with his friends, he encountered a monster he heard about in stories. Faced with death, he summoned the True Longinus for the first time and slew the monster. Half a year later he would meet Sun Wukong who would reveal his ancestor Cao Cao to him. After being sold by his parents to strange men, he ran away from home but was chased down by men wielding weapons, human traffickers and wild animals. A few years on the run, he left China for another country and would learn how to use True Longinus and come to know it is a Longinus and one of the Holy Relics. He abandoned his birth name for the name of the hero "Cao Cao". Returning home, he learned of his parents' death due to a huge amount of debt in money and left thereafter to form the Hero Faction, becoming acquainted with Indra through Sun at some point.
Cao Cao first appears at the end of Volume 6, talking with Siegfried on the defeat of the Old Satan Faction, sarcastically saying that it is too bad their Dimension Lost user did not go all out to which Siegfried replies that it was Cao Cao who gave that order.
In Volume 7, Cao Cao is seen talking with Siegfried who warns him that they are close to being discovered, to which Cao Cao replies by saying that they have gathered enough talent and can start the next phase.
In Volume 9, Cao Cao made his official appearance to Issei and his friends during their class trip in Kyoto. He and the rest of the Hero Faction were responsible for the kidnapping of Kyoto's Youkai Leader, Yasaka, with the intention of opening the Dragon Gate to summon the Great Red. This attempt, however, was stopped by Issei and his friends along with the last minute intervention of Sun Wukong. In the process, Cao Cao lost one of his eyes to a final blow from Issei.
Cao Cao reappears in Volume 11, attacking the Gremory and Vali Teams and Azazel in order to capture Ophis. With assistance from Samael and Georg, while targeting the weakness of his opponents, Cao Cao was able to dominate the battle, defeating his opponents, even shattering Xenovia's Ex-Durandal in the process, and successfully stole Ophis' powers.
In Volume 12, he appeared in the Underworld after Issei and the Gremory Team defeats the Hero Faction, challenging Issei to a fight, which Cao Cao was able to dominate, but eventually lost after Issei used a bullet with Samael's blood on his Medusa's eye, weakening him. In his last attempt to defeat Issei, Cao Cao attempted to use the Truth Idea but did not work due to the will of God in the True Longinus, choosing Issei's dream instead of Cao Cao's ambition. He was then rescued by Georg who carried Cao Cao and Leonardo until they meet Indra who proceeded to take their Longinus and sent Cao Cao and the other two to the Realm of the Dead.
Cao Cao returns from the Realm of the Dead in Volume 16, reclaiming the True Longinus from Indra, who complimented Cao Cao on his return, to which Cao Cao replied saying that it was Indra who sent him there in the first place.
Cao Cao helped defend Heaven from the attack of Qlippoth in Volume 18. He fought against Ladon and was able to trap him inside a crevice for Rias to use her Extinguish Star to destroy Ladon's body and for Koneko to seal his soul inside a jewel that came from Issei's armor. After the battle, Cao Cao mentioned that he was bored with fighting Ladon, and he only viewed Issei and Vali as dragons worthy of combat. When asked why he returned, Cao Cao replied that he wants to know why the True Longinus was given to him.
In Volume 20, Cao Cao visited Vasco Strada, who was currently under house arrest. When asked why he'd come, Cao Cao said that he wanted to know what a "Hero" is. After explaining what he thought was to be a hero, Strada laughed and told him that he was too young to consider himself a hero. Strada then proceeded to explain that it is the people who decide who will become a hero. After Strada explained why he had fought for the Church, Cao Cao thought to himself that Strada resembled Issei.
In Volume 21, Crom Cruach and Cao Cao arrive together to assist D×D's army faction at coastal waters of Japan, at the last stand against Qlippoths army controlled by Apophis.
In Volume 22, Cao Cao was sent to observe Issei's promotion to a High-class devil on Indra's behalf and was caught eavesdropping on Shiva's conversation with Issei. He tells Issei he got permission from Indra to participate in the Azazel Cup and stating he wishes to crush his team.

Cao Cao made an appearance in the opening ceremony of the Azazel Cup, officially joining the tournament as one of the participants. Upon Issei's arrival to the opening ceremony, Cao Cao chuckles as he says he has the opportunity for revenge, with Issei telling him he will defeat Cao Cao.
Cao Cao reappeared in Volume DX.4, with him meeting Issei at the capital of the Underworld without his True Longinus and exchange glares with Sairaorg and walking pass him telling him that he’s looking forward to their match. At the residential area of Lilith Cao Cao paid Heracles a visit and sees him working on flower beds and apologized to him for coming to his work and it’s because he wanted to see how he was doing and Heracles remarks that Cao Cao has changed a lot. Cao Cao and Heracles travel together to the Vatican and meetups with Jeanne who was working as a waitress upon her capture during the Monster Crisis. Cao Cao sarcastically says to Jeanne that she had become one of the training chefs in Vatican and Jeanne complained saying if she truly inherited the soul of Joan D’Arc she should’ve aided the people. Jeanne notice that Cao Cao and Heracles have changed a lot and asked Cao Cao why did he decide to involve the two of them which he responded saying he wants to test his current self. Cao Cao was asked by Jeanne if he wants to fight the Two Heavenly Dragons fair and square and he doesn't know if he can beat them right now, shocking Jeanne and teasing says that the confident Hero Faction leader became so humble but Cao Cao is still angry about the humiliation, helplessness and fear won’t go away until the day when he finally defeat them. Cao Cao, Jeanne, and Heracles meetups with Connla and Marsillio who brought them Georg who return from the Realm of the Dead due to Hades’absence and Cao Cao calling him. After noticing that Leonardo isn’t with him and he’s at the Grigori’s lab, Cao Cao believes they won’t allow a person who can give birth to monsters easily join the tournament. Cao Cao and his team were joined by Perseus who agrees to join the team for the tournament and Cao Cao handed files to his team regarding Sairaorg’s team and his backup members from Magdaran Bael’s peerage members as their meeting starts. At the floating city of Agreas, Cao Cao arrived together with his team for their match against Sairaorg and his team at the arena and exchange glares at each other.

Cao Cao appeared at the center of the battlefield to face Sairaorg but he expressed his disappointment for being unable fight him because Heracles wanted to fight him, however Sairaorg says he’s rather grateful because it helped him feel ready. Cao Cao noticed the similarities between Sairaorg and Issei and revealed he discarded all his strategies so he can fight Sairaorg one-on-one fight and as the match began he sent several jabs at Sairaorg but managed to dodge all the attacks. Cao Cao distanced himself from Sairaorg after figuring out his attack range. When he equipped his Balance Breaker, Cao Cao decided not to use his Seven Treasure and instead use his energy into the holy spear so he can defeat Sairaorg and Issei with simple techniques rather using his special moves. After Sairaorg entered his Breakdown the Beast armor form, Cao Cao continued to dodge his attacks using his vision and senses but took some damage due to Sairaorg’s aura. Cao Cao managed to destroy Sairaorg’s shoulder armor with his spear and caused some serious pain to him with the holy aura and thus forcing his opponent to dodge his spear attacks. Cao Cao started his counter against Sairaorg by sending attacks to where he would go. Sairaorg’s punches became less sharp than before to the point where Cao Cao was able to dodge them easily now. He was able to prevent Cao Cao from getting closer by emitting aura from his body, but it was a matter of time before that aura was penetrated by Cao Cao’s holy spear. Once that aura became weak enough, Cao Cao’s single jab would end his fight. After Sairaorg’s punches became sharper again, Cao Cao tried to slow down the attacks with his spear, but Sairaorg managed to punch the spear away. However Cao Cao managed to stabbed his left side. Cao Cao became exhausted after wasting a lot of energy which gave Sairaorg a chance to land a strong blow on him but Cao Cao use his True Longinus to defend himself against Sairaorg’s punch. The punch sent Cao Cao flying across the field and tumbled the ground several times. He managed to get back up despite the damage he took and they decided to continue to fight each other despite the exhaustion. The match is over with Cao Cao and his team as the victor due to having more points than Sairaorg’s team.
Cao Cao appeared in Volume 24, at the Black Dog BAR and warned Issei that Lavinia is Vali’s and Tobio’s princess and not get carried away. Tobio revealed they both exchanged information since they are both agents of the Grigori and he ordered a glass of hot milk. Cao Cao is honored that Issei says his matches in the tournament are good he expressed his wish to fight him and Tobio. Cao Cao explained that the perpetrators they captured were devils whose identity and affiliations were unknown and couldn’t find any clues at all after comparing them to all of the devils registered in the Underworld and hide the evidence of the higher-up devils. Cao Cao reminded everyone about Indra’s only focused in the tournament is about Shiva and until the tournament ends he will not be making a move. Tobio asked him if he is ordered to eliminate anyone who plans to hinder the tournament and Cao Cao agrees saying his target is the Grim Reapers.
In Volume 25, Cao Cao was sent to pick up Issei by Indra in order make him stronger. Issei was surprised that Cao Cao would come to get him despite being busy, Cao Cao shrugged saying he is Indra’s vanguard and has no choice but to do what he says and leaves with Issei to the Ocean of Milk. After Indra greeted Issei, Indra ordered Cao Cao to start the aforementioned preparations and he exasperating agrees and telling him he’s a god who likes ordering humans around and began working on the sandy beach. After the preparations were almost complete Cao Cao sat the corner of the sandy beach after filling the plastic pool and was ordered to hold the tail of the legendary giant turtle Kurma while Issei holds it's head. After Issei drank the miracle drug Amrita, Cao Cao was ordered to look after him so he doesn’t lose consciousness and watched as Issei suffers from the effects of Amrita and began to lose consciousness. Cao Cao watched over Issei until he regained consciousness as he told him he’s been out for a day and he came back fast.
Cao Cao participated the celebration at the Hyoudou Residence to celebrate with his Hero Faction team for passing the preliminaries of the tournament along with rival teams and he expressed his interest of wanting revenge in the main stage.
Cao Cao reappeared in True Volume 1, at the Hyoudou Residence where he gives intel on Ingvild Leviathan to Issei about how she was kidnapped by unknown devils. After Issei was attacked by the Greek goddess Nyx, Cao Cao arrived together with Tobio at the Hyoudou Residence to give their information on Nyx’s whereabouts. Later Cao Cao arrived to assist the sword group on their fight against the devils where he saved Lint Sellzen from a devil by piercing in its abdomen. Lint recognizes him as Siegfried’s friend and he agreed that he is his friend.
In True Volume 3, Cao Cao and his team arrived to the Shinkansen platform together with the Slash Dog team as escorts and he revealed that he’s been entrusted to Urakyoto’s security and was given complicated expressions from Kunou and he tells Issei so she could hear him that he wants to apologize to Yasaka and Kunou for his actions at Kyoto.
