I'm here to save you all from the biggest lie in history: Freedom. It’s the truth of humanity which we never speak about: we crave for subjugation. The bright light of freedom diminishes our life’s enjoyment, in a mad scramble for power. You were made to be ruled. In the end, you always kneel before me.
~ Hao

Hao is player of Sword Art Online and New ALfheim Online. He is the final antagonist in Sword Art Online: Clashing Blades, Sword Art Online: Blade Master, and one of the principal antagonists in Sword Art Online: New Aincrad. He was the former the second in command and later the leader of Guardians of Darkness. After SAO was cleared, he became a New ALO player and became the leader of his own guild, The Supreme Legion.


Reality / Sword Art Online

He has jet black flame-like hair and golden eyes. He uses a long black overcoat with gold details and matching pants and boots, as well as a red undershirt and red fingerless gloves. His belt has the symbol of what would be his armor's crown, and later the symbol of his guild.

After obtaining Skeith his left eye affected on the user is the appearance of the left eye of the user, which always glows and leaves a visible color trail in the air over the eye while Skeith is in use. Hao's color was dark orange, matching his golden eyes. After this, and obtaining Supreme Weapon, he began to use his other sword, Medorach, slung over his back, with the handle at the left side of his head.

In Sword Art Online: Blade Master, his appearance is slightly different. Hao's hair reaches his eyebrows and is straight and neat. He wears a white shirt over a black overcoat with yellow trimmings and sharp edges. He also spots black pants and boots of the same color with yellow trimmings. His belt is dark grey and the buckle is the insignia of The Supreme Legion.

ALfheim Online Avatar

The Supreme King's avatar does not differ from his SAO avatar, and therefore, it matches his real-life appearance. He is a shadowed figure dressed in an armor named Incursio


Hao displays a keen, intelligent, power-hungry attitude, capable of doing anything achieving the task of becoming the King of Aincrad at any cost. He is extremely confident, bordering on arrogance, and selfish. To an extent, he displays a god complex, believing himself to be the sole potentate and only person worthy of the title of King of ALO, even superior to the Aesirs, the Gods of ALO. He has a polite, yet strong, way of speaking, often using elegant words. He occasionally mocks people by calling them "mongrel", "wretch", "fool", "weakling" among many other insults. However, he rarely swears.

Hao lacks a belief in freedom, stating that it is the reason why humans never find peace and that freedom is the biggest lie in human history. He states that to find peace, they must banish freedom and chaos by any means possible (even immoral means), to replace it with control and lack of free will. He displayed this ideology both during SAO and ALO. He first wanted to force all the remaining players to join a single guild so that he could assume the position of GM, and then lead the players in the clearing all the floors in Aincrad. On ALO, he wants to create an everlasting Kingdom and make sure no other tragedy, like SAO, happens within ALO. In his own mind, Hao is not driven by a selfish desire for power, but rather, a selfless one. Hao sees himself as a righteous soul who is doing whatever it takes to save as many people as he can and sees those who stand against him as naive or foolish.

He sees every cruel act he commits as "necessary evil" and displays cold and ruthless pragmatism at the time of dealing with problems, stating that sometimes the unpleasant thing is a necessary thing. He is a firm believer that the "the end justifies the means". Despite being capable of cruelty, Hao does not derive any sort of pleasure from the brutal actions he commits or he orders his men to commit.

Surprisingly, Hao has a sense of honor and morality. He can also show respect and even admiration, to enemies that manage to somehow impress him, such as Kirito, Galant, Jack, Yamato, Ishi, and General Eugene. This respect leads him to not underestimate what they are capable of. He is able to see that forcing his will on to others will generate some sort of resistance, which is why he tries not to see his "necessary" actions as something strictly personal. That being said, when somebody becomes stubbornly annoying to the point of constantly frustrating Hao's plans, Hao will take notable enjoyment in the destruction of his enemies.

Despite being capable of killing people to achieve his goals, Hao holds a deep hatred for those players who kill for fun or sport, such as members of Laughing Coffin. He thinks that, if somebody is willing to kill somebody else, he first needs a proper reason to do so. His pragmatism makes him see death as a necessity, and he would prefer not killing if possible. Nevertheless, he can make an alliance with a notorious player killer, such as his cousin, Mordread, if he sees this as a potential benefit.

He is also a keen strategist, he is very calculative and holds great intelligence, reasons why he first became the second in command in the Guardians of Darkness, and later, the leader of the most powerful guild in ALO. Hao is also a master obscuring all that he does, shrouding his moves in deception, making him very unpredictable. He is able to easily distance himself from conflict but at the same time being dangerously close to it. He can to quietly manipulate others into doing things for him. His intelligence alone makes him a dangerous enemy. He has great patience and waits for the exact and perfect moment to make his moves. However, even he has a limit to his patience and courteousness and can show sudden bursts of impulsiveness and violence when angered enough.

Naming himself the "King of Blades", he believes that every great weapon or treasure of the world belongs to him, a reason one of his goals is to obtain Excaliber, the strongest sword in the ALO-SAO universe.

Hao has a softer and caring side, which he only shows to people close to him. He holds great love for his younger brother, Markus, even though he does not generally show it and is very harsh on Markus's impulsive and spoiled nature. He wants him to earn respect on his own, rather than just get it from their sibling bond. He is also very tender with Freya, his personal attendant, and secret lover. He also has a remarkable friendship with his best general, Zar. Hao's greatest weakness, however, is his oblivious nature to the conflicts of those closest to him, which has resulted in several damages within the effort of the army.


Hao's parents died sometime when he was young under unknown circumstances. They were then adopted by his abusive uncle, who mistreated, beat and made suffer both him and his smaller brother. This mistreatment suffered made Hao the person he is in the game.

Sometime later, Hao escaped alongside his younger brother. They came back once they found out his uncle had died. He acquired the game SAO and was trapped alongside the other 10000 players. Among them, was also his cousin, Mordread. After several months, Hao became a member of the Guardians of Darkness and quickly ascended to the position of second-in-command. Hao's ultimate goal in SAO was to force all players to join a single guild and lead all the players remaining out of the game or/and defeat the Game Master (this was never properly explained in SAO: Clashing Blades). He sought the power of the glitch Skeith to achieve such goal.

Once SAO was cleared, Hao was trapped alongside the other 300 players in ALO. He was eventually released from that game as well.

After New ALO came out, he joined the game and decide to finish what he started, forming his own guild "The Supreme Legion". The guild quickly raised, and with strategic leadership and organization, the legions conquered most of the floors arriving at the 50th floor of New Aincrad in August 2026. Hao is the current de facto King of Aincrad, seeking to win the Great Aincrad War, get to floor 100 and complete conquering the castle. Hao's ultimate goal in ALO is to create a kingdom strong enough so that no other tragedy like SAO ever happens again.


New Alfheim Online


Hao loves his brother and he has been like a father for Markus, as he has also always taken care of him as such. Markus joined New ALO to prove that in the two years that Hao was imprisoned, he has grown up to become a man. Hao wishes his brother to prove his own worth and is constantly scolding him about how to be a leader. Markus, however, does not like this, since he considers he talks to him like if he were a child (which, in fact, he is). However, Hao trusts in his brother enough to name him second in command of his army.

Their relationship becomes very strained when Hao strips him of his title as second in command and later when Markus' best friend, Taikeus, is executed during the punishment Decimatio, for failure during a battle against KoB.

Eventually, Hao restores Markus' title as second in command when he proves he is worthy of trust again.


Hao and Zar meet for the first time on ALO, after the later joined the guild, and after time, they became close friends. He has a lot of trust in his abilities as a general and a tactician. He recognizes that Zar is wild, but he also sees he has a natural brilliance, reason why he commanded him to take the vanguard in the clearing of Aincrad.

Zar is one of the few people Hao sees as more than a subordinate, but also a good friend.


Hao views Kirito as someone worthy of respect. He even admires Kirito's intellect and his prowess as a warrior which had made him gain reputation through SAO and ALO. But also recognizes that he is a great threat to his plans in ALO.


Freya is Hao's helper. They are secretly in love with each other.

Their relationship became notably strained when Freya left the Legions and joined the Knights of the Blood. This eventually lead to Hao being extremely angry and obsessed with defeating Kirito. However, Hao still harbors feelings of love towards her.


Mordread is Hao's cousin. Mordread is one of Hao's principal right-hand men, and they allied their guild to win the Great Aincrad War. They have an often tense relationship, with Hao disliking Mordread's disrespectful nature. however, Hao keeps him close to manipulate him into doing his bidding, as he sees Mordread as little more than a rabid dog.

Their relationship becomes very poor when Hao violently assaults Mordread after the latter doubted of his potential to win the War and reminded him that Freya had left him. Hao then sends Mordread to defeat an upcoming army formed by multiple ALO fairy races.


They never crossed paths in SAO, still, Hao knew of Galant's deeds and achievements. He developed respect pretty much as he did with Yamato and Ishi. He had nothing to do with Mordread and Kamui killing the Royal Knights, nor did the knew.

Galant is one of The Supreme Legion's mercenaries and he only takes direct missions from Hao himself. They have a good relationship and respect one another. Hao has offered Galant joining the leadership of his guild on repeated occasions, but Galant always refuses. However, after learning of Hao's alliance with Mordread, Galant resigned fighting for Hao and join the Knights of the Blood. Since then, they have been enemies.


When Jack joined The Supreme Legion, he had a friendly relationship with Hao. This lasted until Hao's legions slaughtered his race.


Tyr is Hao's most trusted and loyal colonel, so much that he has risked his life several times for him. Hao recognizes his skills and respects him.

Sword Art Online


Hao began his relationship with Pendragon Court, and Ishi was his contact. Hao knows he isn't trusted, as he doesn't reveal how he obtained information. Still, they need him, because he knows way more than others. It is unknown why he began relationships with them while being an enemy, and it seems that not even Kamui knows. Hao admires Ishi's skills, and the fact that he is a blade master, still, he recognizes him as a trouble in his plans.

Ishi was tricked by Hao into killing Kamui before Hao stole Skeith from him and stabbed him in the chest, leaving him for dead. Once he was back, Hao and Ishi are declared enemies, as Ishi is the biggest problem with his plans.

In the end, Hao was defeated by him as was his army, but even still, Ishi didn't kill him, as he considered him "unworthy of an honorable death". Ishi was one of the two players who managed defeat Hao, the other being Kamui.

Ishi Haseo

In the Sword Art Online: Blade Master continuity, their relationship is slightly changed.

Hao began his relationship with Pendragon Court, and Ishi was his contact, under the promise of sharing information regarding the nature and occasional whereabouts of Corbenik. He would also keep a close eye on Ishi, due to his possession of Skeith, seeking to gain its power for himself.

Hao respected, even admired, Ishi's skills as a player. However, Ishi's mental stability, his erratic player kills and his possession of Skieth were the factors that lead him to want to eliminate Ishi. Hao is the one who orchestrated the death of Ishi's close friend and lover, Misaki Akimi, in order to draw out Skeith from him, succeeding in gaining some of its power. After Ishi discovered this betrayal, he became the primary threat to Hao's plans, especially after Ishi's training under Yamato Ovan.

The two would come to battle each other, and after a long and grueling fight, Ishi would defeat Hao. However, just as Ishi struck the death blow, Sword Art Online came to an end, with Hao just narrowly escaping his death by Ishi's blade as a result.


Hao holds hatred toward Kamui for reasons that aren't completely revealed. It is widely believed that the reason is a clash of ideals: Kamui has a more chaotic ideology while Hao hates chaos and anarchy. It's known that Hao is scheming behind Kamui's back, but to that end it is unclear. 

He was successful in tricking Ishi into killing Kamui, therefore assuming the leadership of The Guardians of Darkness for himself.


The same as with Ishi, Hao recognizes Yamato's skills and respects him. After all, they share Kamui as a common enemy. He still recognizes he can be a trouble with his plans. Hao was one of the few players who stood near to kill Yamato.

Yamato Ovan

In the Sword Art Online: Blade Master continuity, their relationship is slightly changed.

The same as with Ishi, Hao recognizes Yamato's skills and respects him for them. He doesn't recognize Yamato as a direct threat until he begins training Ishi in the use of the sword and Skeith, realizing the great threat Ishi would pose to him as a result, though Hao himself would never get the chance to remove Yamato from his plans.

Akihiko Kayaba

Though they never met in real life nor in-game, Hao has conflicting feelings about the creator of SAO. On one hand, he holds admiration for Kayaba's intelligence, but at the same time, loathes the fact that he captured 10,000 humans within a game for a year, causing the deaths of thousands of them. Kayaba's existence and the crimes he had committed were what ultimately motivated Hao to force every player to join a single guild so that they could win the game or beat Kayaba.

After Hao was released from ALO, being one of Sugou's 300 test subjects for his experiments, Hao found out that Kayaba had been Heathcliff all along, and was somewhat impressed that one had figured that Kayaba was in the game for so long.

In ALO, his objective of conquering Aincrad and then ALO comes from the fact that he doesn't want anyone like Kayaba to take control of the game.


Hao is an unmatched swordsman. His sword abilities make him the second-best warrior of the Guardian of Darkness, only bested by his leader Kamui.

After obtaining his unique skill, Supreme Weapon, Hao's level of power increases drastically, easily matches the strongest players of SAO. He can shoot weapons out of nothing, has (presumably) unlimited weapons inside his storage. By the time he joined New ALO, he can skillfully wield any type of weapon. He is skilled either with one or two: swords, spears, daggers, hammers, maces, axes, scythes, shields, halberds, etc... Even when he knows how to fight with numerous types of weapons, Hao prefers to dual-wielding swords, achieving a level of power that is not matched easily. Still, Hao rarely fights in close quarters, preferring standing with his arms crossed while his weapons rain down upon his enemies. He only fights in close combat with players he deems worthy of facing or who have earned his respect or when he is left without any other choice.

Hao's sheer amount of power does not come from his number of weapons alone, but also from the Unique Skills that his weapons posses. For instance, he owns a trident that electrifies anything it clashes against, a spear that pierces through armor and another which deals unhealable wounds. Among his strongest weapons are: Gungnir, a spear which always hits its target, and chains meant to hold his opponent. His most powerful weapon is Blutgang, a weapon capable of absorbing incredible amounts of magical energy and, once he swings it, a crushing torrent capable of pulverizing any opposition is launched towards his enemy. Hao holds incredible pride on this weapon, and won't use it against those he deems "unworthy".

Hao can also absorb weapons from defeated players, to add it to his "treasures". He regularly trains with his men. While doing this, he uses heavy swords, trying to improve even further his speed. He is also capable of facing several opponents at once, depending on their skill and power. Hao is able to move fast and agile with his armor, almost as if he was not wearing any armor at all.

While he held Skeith, as he Hao contained it within an amulet instead of within himself,  he cannot unlock its full power. Still, Hao prefers this, since he considers that losing his sanity is a huge cost. Even still, he is capable of using Skeith with some restrictions.

Tactical Ability

Hao is also a skilled, intelligent, and highly cunning tactician who, unlike his officers and high-ranking soldiers, does not adhere to typical tactics and traditions, making a more flexible strategist. And he does not underestimate his opponents at all, neither he overestimates himself. His tactics are a mirror reflection of the strategies used by lords of war of actual history, though he relies mostly on the Roman Republic/Empire.

He is such a strong tactician that he managed to orchestrate the entire war between Pendragon Court and The Guardians of Darkness without being caught and successfully tricked Ishi into killing Kamui and taking leadership of The Guardians of Darkness while leaving both Ishi and Pendragon Court to be killed, stealing Skeith directly from Ishi and containing it within an amulet.

The combination of bold unpredictable strategy and his skill with weapons make Hao a fearsome opponent. One no one would wish to face upon the field of battle.
