- Aura (アウラ) is an advanced AI that takes the form of a young girl whose white hair, skin, and garments give her a ghostly appearance. She is created by Harald Hoerwick to be a symbol of his love for his deceased lover as the daughter that could have been. She is the perfect AI, and is the spirit of The World. Since her awakening by Tsukasa, she has been fleeing the clutches of Skeith, as witnessed by Orca and Kite, and several other players as well. She is meant to be the perfect AI that will take in collected player information by Data Draining the current AI control program, Morganna, though Morganna intentionally keeps Aura in her sleep-like state to keep her purpose. After Morganna's plot to keep her asleep by using Tsukasa in .hack//Sign fails, Aura awakens and becomes hunted by Morganna's Phases to prevent her from developing Data Drain.
Aura manages to cultivate this power into an installation book, which ends up in the hands of Kite. Aura becomes Data Drained afterward, which causes her to be scattered throughout The World. She manages to communicate with Kite and other players through corrupted e-mails, which leads to the defeat of most of the Phases. During the final battle, Aura is scattered again and merges with Morganna to complete the Ultimate AI. She becomes an omnipresent yet mostly silent force within The World for some time. She eventually sets out to perfect herself by interacting with the World by giving two players, Shugo and Rena, chibi versions of the avatars of Kite and Blackrose in a contest, and giving birth to another AI, Zefie. This helps Shugo reach his goal of becoming a hero. Aura's eventual disappearance causes The World to decline. Consequently, the CC Corp develops Project GU to recreate her.

Kite is the close friend of Yasuhiko, who plays online as Orca, in their school, so Kite joins The World and meets up with Orca. Soon after, Yasuhiko is placed in a coma by Skeith, and Kite receives the Twilight Bracelet from Aura, allowing him to Data Drain. Following leads set by Aura, Kite defeats the various Phases and Cubia, the alternate side of the bracelet, destroying the bracelet. Aura eventually gives him a new bracelet called the Dawn Bracelet.

His job is to work out any glitches in the game, as well as delete any system anomalies. He is set to hunt down a Vagrant AI, Lycoris, as part of his job, though he later meets her and befriends her, not knowing her true nature. He helps her regain various pieces of data, along with Hokuto, a newbie player, and when completed, Lycoris realizes that she cannot exist and forces Albireo to delete her. Albireo reappears in .hack//AI buster 2, chasing after Tsukasa, though he soon runs into Macha and is rendered comatose for several months.

He is a Blademaster, who is given white wings after the event as a reward. He can use them to float and jump higher than other players. Balmung is originally very formal and assertive of his views, following a strict moral code of doing good in The World, leading some to consider him arrogant or rude at times. He truly loves The World and takes playing it very seriously, to the point of investigating disturbances within it personally and refusing to speak with .hackers or associating with them. In .hack//Legend of the Twilight, he's much more carefree and less serious with new players, though still completely business-like with his associates.

He creates a virtual daughter, Aura, designed to receive data on humanity and its various emotions. His plan goes wrong when the program designed to nurture Aura, Morganna, decides to bend its own programming to stay in existence. Obsessed with completing Aura, he decides to rid himself of his physical body and become part of The World. Morganna traps Harald and restricts him to inaccessible areas, leaving him as "The Broken Man", where he loops dialogue expressing his regrets and the error he made in creating Morganna. He eventually helps Bear and his companions get on the right path to Aura, but Morganna deletes him soon afterward.

Elk shows a great loyalty to and infinite concern for his odd companion as her mysterious condition slowly worsens throughout the game. He eventually accepts Kite and his companions as they work together. In the next version of The World, Kaoru Ichinose (一ノ瀬薫), the player behind Elk, creates Endrance (エンデュランス) the Temptress. Endrance is cold towards other players, referring to them as "ugly dolls". Endrance is online for most of the day, logging off only to sleep, and interacts with a small cat, which he believes to be the reincarnation of Mia. The cat is actually an AIDA feeding off his emotions by acting as Mia. Haseo eventually destroys the AIDA while fighting Endrance.

- Crim (クリム Kurimu ) is a Long Arm featured in .hack//Sign. His avatar is a male with spiky blue hair, a red jacket, flared red and yellow pants, and a wave symbol on his chest. Crim plays as a very happy-go-lucky character, easygoing and sociable. He enjoys testing his skills against strong opponents and is always ready to help anybody in need. He founded the Crimson Knights with Subaru, though he eventually leaves. He is very close to Subaru, as he knows that she is handicapped and offers his phone number to her if she feels the need to talk.

Helba's name comes from the long lost net-distributed text, the Epitaph of Twilight. She finds files of an unused town and creates a patchwork area which she names Net Slum. It is a sanctuary for Vagrant AI, trash data, and other illegal items. It is suspected that she made a brief real-life appearance in Liminality as Kaoru Asaba, a strange woman who helped Yukichin in the second episode.

- Mia (ミア) is a Blademaster with the appearance of an anthropomorphic cat with purple fur and long rabbit-like ears. She is a truly strange character, made increasingly strange by her ability to see Kite's Bracelet. While she thinks she is a hacker with advanced skills, she is really just an incarnation of the Phase, Macha. She is close to Elk because she unconsciously sees the resemblance to Tsukasa, a friend from the previous incarnation, and she is constantly on the look out for an item called "Aromatic Grass." As Kite defeats each phase, she loses her memory and begins to wander the root towns. As The World becomes more corrupt, she eventually awakens in her full phase form, Macha the Temptress. She is destroyed, and Aura revives her afterward. Mia is captured and killed after the Project G.U. (aka: Project Roots) staff remove the Temptress data from her. The original "Macha" is an AI character created by Morganna to follow Tsukasa and make sure that he never leaves the game. She eventually turns on Morganna and sacrifices herself to save Tsukasa and the others. After Macha was data-drained and killed, her data was reconfigured as Mia, who later meets Elk, a Wavemaster.
- Mimiru (ミミル) is a female Heavy Blade who appears in .hack//Sign. Her avatar appears as a teenage girl dressed in an armored bikini top and a short skirt, with large greaves on her legs. The outfit is the same design as BlackRose's, albeit with a different color set and wave design. Mimiru plays as a "tough-it-out-through-anything" player, who is poor at planning and following through on those plans. Nevertheless, she has a big heart with bigger attitude, which is a great asset. She meets Tsukasa and soon becomes one of the few he trusts, eventually befriending him. She also teams up with Bear, whom she refers to as an "old man", and spends considerable time in the series attempting to figure out what Bear's career is in real life. She eventually meets with An Shouji, Tsukasa's real identity, and the two go shopping together in Shimokita. In real life, she is a 15 year-old teenage girl, who is an only child and has few friends.

- Morganna Mode Gone (モルガナ・モード・ゴン Morugana Mōdo Gon ) is an AI system created by Harald Hoerwick to oversee the birth of Aura by gathering personality data of the players of The World and allowing herself to be absorbed into Aura. However, Morganna eventually realized that after Aura's birth, she would have no purpose, so she attempts to stall the growth of Aura indefinitely, resulting in many of the events in the .hack series. In .hack//Sign, she imprisoned the character Tsukasa in The World and tried to use his negative emotions to keep Aura from waking, but the plan failed. She is able to bend her programming by succumbing to a paradox, though she eventually breaks her programming and takes on the persona of the Cursed Wave from the Epitaph of Twilight. She exists everywhere in The World with the exception of glitched areas, and when she is damaged, The World becomes corrupted.

His avatar is an edited version of the standard Crimson Knight design, with full chest and back plates added to his armor, horns added to his helmet, and red eyes instead of blue. He possesses a strong sense of justice but is also extremely naive, leading him to end up as more of a tool to be used by whoever is in control. He is extremely overprotective of Subaru, more so than anyone else. Silver Knight also appears in the .hack//Legend of the Twilight anime, where he helps Shugo until his character is deleted by the Cerulean Knights. He makes a third appearance in .hack//Roots, where he offers Haseo his assistance after stating that he has been in a similar situation. Haseo refuses his help.

- Skeith (スケィス Sukeisu ), known as Skeith, the Terror of Death, is the first of Morganna's phases to be created. He first absorbs Sora using Data Drain and then is sent out to find Aura. His avatar appears as a humanoid seemingly made of rounded rock with floating disjointed appendages and a two-piece ring shaped horn. Skeith carries a red staff, upon which he 'hangs' (similar to cruxificion) his victims prior to Data Draining them. He resides in an amnesiac Sora until Aura is found. Skeith seals Sora within his staff. He drains Orca, which places Yasuhiko into a coma. Kite eventually fights and defeats Skeith. Skeith is recreated with the other Phases as part of CC Corporation's plan to reconstruct Morganna, though the plan backfires. Based on Sora's condition, the corporation gave him the ability to fuse with players. The seven Phases absorb the consciousness of their players and escape into the network. (The eighth, Tarvos, had already been stolen and hidden away halfway through the plan), where they waited for the right person to "connect to".

She eventually comes into contact with Tsukasa and forms somewhat of a romantic bond with him.

At first, Zefie is selfish, spoiled, and rude, but matures through her interaction with Shugo and Rena.
- Piros (ぴろし) is a Heavy Axeman and a strange one at that. Piros believes he is the true protagonist of the story and refers to Kite as "he of fair eyes." ("Ii me wo hito shita yo"). His odd speech pattern is not as odd as his character model – Piros appears to have a shrunken head, given the Brobdingnagian proportions of his body. He involves Kite in his misadventures... which are usually the result of his naivety. Although he can be very childish at times, Piros is actually a graphics designer, a programmer, who spends his time playing The World. Voiced by: Masaya Onosaka (Japanese), Darran Norris (English)
- Sanjuro (砂嵐 三十郎) Voiced by: Yasunori Masutani (Japanese), Steven Jay Blum (English) is heavy blade player in the game, Sanjuro is an American man who loves Japanese films – specifically samurai films and the work of actor Toshirō Mifune and director Akira Kurosawa. Indeed, the only thing Sanjuro may enjoy more than samurai films is telling people about his favorite samurai films. His love may extend past films and may encompass all things samurai, considering that his character model is a samurai and he has a small obsession with collecting katana – kotetsu swords in particular. He is optional, and can only be found if the player reads his message board entry and helps him find a rare weapon.
- Gardenia (ガルデニア) Voiced by: Yumi Touma (Japanese), Carolyn Hennesy (English) is a quiet Long Arm with a great love for flowers, she takes Kite to fields that have something to do with flowers in the name. Though she appears quite mysterious, she is not truly a part of the conspiracy that the outlaw player Kite is battling. Gardenia is a true romantic even though her personality is a little on the hostile side. She enjoys foreign films. She is also optional, though her recruiting manner is different. To acquire Gardenia, you must read a message board post from her "groupies", and go to their meeting place, where Gardenia will join you in the hopes of keeping her unwanted fans off her back. She resembles the character "Mimika", who Mimiru saw use "Ap Crystal" in the episode "Intermezzo", but, contrary to popular belief, is not one of the three players who controlled Mimika.
- Natsume (なつめ) Voiced by: Maaya Sakamoto (Japanese), Lia Sargent (English) is A Twin Blade just like Kite, she is in a constant search for more power and fears that she will never be good enough. Her character model is the same as the lesser known A-20 of .hack//Sign. Despite this, she still has an upbeat nature and is a welcome addition to any team. In real life, she is in the ninth grade, and she plays The World to make herself more confident in the every day trials of life. Like Sanjuro, you must read her weapon-hunt request and help her acquire a rare sword before she will join you.
- Mistral (ミストラル) Voiced by: Atsuko Enomoto (Japanese), Sandy Fox (English) is a Wavemaster who joins Kite's campaign quickly, she is a treasure hunter and a young woman with bright pink hair that is outshined only by her eternally cheerful personality. She is truly an oddity among the friends that Kite makes within the game, as there is little to guess about her. Unlike the others, she plays the game just to play the game. While she has no mysterious role or secretive agenda, although she is very fascinated by the Twilight Bracelet, as she is a treasure hunter, she does jump on the bandwagon that is Kite's crusade. She tends to behave much like how a stereotypical MMORPG "noob" behaves: hopelessly enthusiastic, begging to be given rare treasures, and using lots of smilies in her messages. Near the end of the game, she goes "off-line" in order to give birth in real-life.
- Marlo has a rotten personality on the surface. He has a hard time showing gratitude, and rarely says anything positive. He was typically a loner until he joined up with Kite. He seems to like Kite due to Kite tolerating his personality. His class is Blade master.
- Moonstone is the strong silent type to an extreme degree. Usually, Moonstone speaks in one word phrases. When he does speak in a complete sentence, it'll be short. Like Natsume, he is obsessed with increasing the strength of his character, and has a great deal of respect for other strong characters. However, Moonstone does not force anything he desires onto other characters. Always leaving them the option of not participating in his quest for strength. Moonstone's character class is a twin blade. He is also the first character to send you his address though e-mail.
- Nuke Usagimaru is the host of a battle commentary show where he tries to tackle a powerful monster solo, providing humorous commentary and physical comedy while others watch. Though his shows are often failures, Nuke takes it in stride and is always using his past experiences to improve on future shows. Even in normal situations, Nuke acts in a flashy way; it seems to be an innate part of his personality. His closest friends in the game are Kite, who Nuke sees as the ultimate straight man and his ideal partner, and Rachel, who acts as his editor via e-mail. Nuke's character class is a Long Arm and his dress is something like that of a clown. It is implied that he and Rachel have become somewhat famous by time the events of .hack//G.U. occur.
- Rachel is greedy and money-obsessed. She is always cooking up a new idea for making money in The World. If there was an option to make a merchant character, that's what Rachel would have been. She drags Kite into helping her with whatever plan she has currently at work, even though her plans usually fail for various reasons. Despite her obsession with money, Rachel doesn't accept anything that is low in quality. Her character class is a Blademaster.
- Wiseman is a Wavemaster with a calm and collective attitude and an excellent perspective on business. He is greedy like Rachel, but shows it indirectly. He lets on a personality that brings people to think that he is always keeping something from them. His real name is Takumi Hino, a ten-year-old boy who enjoys collecting trading cards and playing soccer.

A List of the Main characters from the second version of "The World"
- Haseo (ハセヲ Haseo ) is an Adept Rogue "Player Killer Killer" and the main protagonist of the .hack//G.U. video game series and the .hack//Roots anime series. He joins the game and he is quickly hunted by player killers until he joins with Ovan of the Twilight Brigade. Ovan eventually disappears, and Shino, Haseo's friend, is placed into a coma by Ovan. Haseo attempts to find power, which leads him to Harald, who gives him power. He eventually tries to face Tri-Edge, though he is completely reset after being data drained. Haseo agrees to assist Yata and Pi, two System Administrators in The World R:2, in their efforts to discover the reason behind recent attacks on players and a sudden increase in AIDA activity. Haseo gains an "Avatar" named Skeith by awakening him, acquiring the ability to call Skeith and wield his abilities. In the real world, Haseo's real name is Ryou Misaki, a social outcast who played as the player killer character, Sora, until he was placed into a coma by Skeith and awoke with amnesia. During the development of the game he grows as someone mature who wishes to protect everyone and that enjoys company instead of his cold and lonely self. In the beginning he was in love with Shino but later found interest in Atoli, however his feelings are never shown or declared except in the game during the special wedding events. However, in .hack//LINK, during Tokio's journey in 2017 timeline, it was shown that Haseo declined Shino's invitation to rebuild Twilight Brigade, and then indirectly confessed his feelings to Atoli. In the English version, Haseo is voiced by Yuri Lowenthal in the games and Andrew Francis in the anime.
- Artificially Intelligent Data Anomaly, shortened to AIDA, is described as a bug or virus, thought to have come from the disappearance of Aura, that defies all system parameters in The World. AIDA afflicts players in the .hack//G.U. series by attacking them and causing them to become insane over time or comatose in the real world. The eight Epitaph Users are partially immune to the effects of the virus and use this advantage to fight it. The bad, viral instances of AIDA are deleted at the end of the game series, though it is stated that good instances exist, who try to exist happily. AIDA may only be stopped by the Epitaph Users' ability to "data drain", an illegal program originally given to Kite by Aura, which CC Corp believes also causes AIDA.
- Alkaid is a female Twin Blade known as "Alkaid, Former Emperor of the Demon Palace." She is part of Icolo's guild, and takes part in the arena battles. She fights with Haseo after an argument, and loses after Haseo uses Skeith to fight for him. She thinks of him as a cheater while leaving.

While searching for information, she is PKed by an AIDA-infected Bordeaux and placed into a coma until the fight with Cubia. Her real name is Chika Kuramoto, a sixteen-year old Japanese girl. She lives in Sapporo, Hokkaido, and is on the library council for her high school. She values reading, and reads both Chinese classics and Western contemporary fiction. In the Japanese version, her name is "Yowkow," the Japanese name for the star Alkaid.
- Atoli (アトリ Atori ) is a Harvest Cleric who becomes attached to Haseo. A pacifist, Atoli is part of the guild Moon Tree under Sakaki's command. She harbors feelings for Haseo, which in the beginning of the G.U. series are unreciprocated, and slowly wane after Haseo slanders Sakaki. However, her affections are later rekindled, after Haseo realizes Atoli was suffering from her desire to be recognized by Haseo. Haseo, who was drawn to Atoli because she used a newly identical Player Character to Shino, had only been looking for Shino in Atoli. Atoli is later found to be an epitaph user when she is separated from her Avatar (Innis, the Mirage of Deceit) by AIDA after following Haseo, Kuhn, and Pi to an area inaccessible to regular players, found inside one the Tri-Edge marks. At the end of vol.3 of .hack//G.U she sees Haseo with Shino at the cathedral because she received an e-mail from Shino herself requesting her presence in the cathedral. After a few words she runs away heartbroken thinking that her relationship with Haseo has ended, but is surprised when she sees Haseo running towards her. Her real name offline is Chigusa Kusaka.

He can also transform into a floating azure orb of light to travel, and often arrives at areas in this form, surrounded by azure flames. He is an artificial intelligence created by Aura that exists to destroy computer viruses and AIDA. He is mistaken as the "Tri-Edge", which leads to Haseo attempting to fight him.
