|“||Be careful, there's a dangerous power hidden inside of you.||”|
Pi is a scantily clad Tribal Grappler. She has long pink hair tied into two large pigtails and wears a very revealing red outfit which snakes down her legs. She wears a small pair of glasses on her face which she frequently fiddles around with when trying to make a point. She has red tattoo with a blossom-like design on her right shoulder.
As Yata's assistant, Pi is required to follow his orders, a job she does willingly, being a consumate professional. However, unlike Yata, she has trouble seeing The World R:2 and its users in an impersonal way. She has the tendency to become attached to people and occasionally breaks the rules in order to help them out. Despite the tough personality she tries to give off, she is prone to occasional moments of weakness, especially when dealing with other people. Nevertheless she is dedicated to both her job and to Yata and does her best to follow his commands.
She is fairly close to the other members of Raven, especially Kuhn, though she insists that she only sees him as a coworker. Pi had a very strained relationship with Haseo. Though she recognizes his skill and power, she initially saw him as nothing more than a rude brat with no manners whatsoever, and considered his personality dangerous based on experiences from her own past. She and Haseo gradually built up a deeper relationship, respecting and understanding of each other, however.
Pi's offline self is a woman currently residing in Tokyo named Reiko Saeki (佐伯令子). She is a workaholic, loves eating out, and has a pet cat. She enjoys driving and owns a Maserati.
The final file on the Terminal Disc is a letter to Reiko from Jun Bansyoya, where he reveals that he's her brother, though they haven't seen each other since she was very little. He also tells her that she's a "Chosen One", and that the Epitaph PC for Tarvos is stored on his PC.
For more information, see Ender.
Reiko played as the character Ender until TaN was disbanded, and then resumed her online activties as Pi. She was then assigned by Yata to track down the remaining members of the Twilight Brigade, namely Tabby and Haseo. To help with her work she restored the account of Saburou, a player who had previously worked for her in TaN. Saburou directly interacted with the Tabby and Heaseo while Pi watched from the sidelines. However, Saburou soon realized that Pi had more power than a normal player should, and confronted her about it; angered with the evasive answers Pi provided, Saburou resigned as her assistant.
Soon afterward Tawaraya returned to The World using the character Tohta. Feeling guilty about the loss of his character, Pi contacted him, but Tohta easily saw through her disguise and recognized her as Ender. He used her to contact Yata and pulled in a favor by requesting that he delete several Real Money Trade players.
Pi was then called in to contact Kuhn, who had awoken his Avatar after coming into contact with an AIDA. She invited Kuhn to join Raven and promised to instruct him on the use of his Avatar. Realizing that there was a serious threat to The World R:2, Kuhn accepted her offer and left Canard to join up with her and Yata. The two began hunting AIDA together. However, their hunt was put on hold when Tri-Edge reappeared and attacked Haseo. Realizing that Haseo's own avatar was about to awaken, Yata began making plans to bring him into Raven as well.
At Yata's orders Pi finds herself busy keeping track of the Epitaph User Endrance and his progress in the Arena. Unfortunately for Pi, her partner Kuhn seems more interested in Nanase than the jobs Yata sets for him.
When Haseo is about to be PKed by Bordeaux, Pi saves him, then leaves, after commenting about a "dangerous power" in his character. She begins to resent Haseo because of how disrespectful he is to her, like calling her an "old hag." She accompanies Kuhn to train Haseo at Δ Great Cursed In-Laws. There, they share with him their knowledge of the Avatars. Although Haseo tries to summon an Avatar for a while, he is unable to do so. Pi begins to provoke him, saying he isn't worthy enough to use an Avatar, but leaves when Kuhn tells her to stop. After they return to Mac Anu and Kuhn leaves, Pi tells Haseo that she came along so both she and Kuhn would be able to stop Haseo if he lost control of his Avatar. Pi states that she and Haseo are very much alike because of their desire to control their Avatar's power.
Pi plays a major role later on as a member of G.U. and is able to summon Avatar Tarvos. During a training mission with Haseo, she ended up getting infected with an AIDA, which in turn forced Haseo into his first battle against another Avatar. Later Pi was one of the two party members to aid Haseo in fighting Azure Kite.
In the manga Pi is a manager in the net game The World. After Haseo is defeated by Tri-Edge she introduces herself as a member of G.U. and explains about a phenomena in the game known as AIDA. At Dead World of Indieglut Lugh Bordeaux is possessed by AIDA and Pi arrives with another member of G.U named Kuhn to intervene. After Haseo is saved, Kuhn explains that the AIDA are beings that can infect people and fuse with their minds. Kuhn also explains that the Epitaph Users are the only power capable of combating them. Following their conversation Pi introduces Kuhn as the Epitaph User known as The Propagation and the doll that saved Haseo is Kuhn's Avatar Magus. As Kuhn adds that Haseo is also an Epitaph User Haseo demands to learn how to use the Avatars. Pi begin tells Haseo to listen and do exactly as she says however Kuhn interrupts her and asks Haseo to come with him if that is what he really wants. Afterward Pi returns to the Serpent of Lore. As Haseo enters battle in the Arena Yata explains to Pi that the AIDA are interested in strong human emotions and Pi watches from the monitor as Haseo activates his Avatar Skeith for the first time in his faces off against Endrance.
In the novel Reiko Saeki investigates AIDA through her character Pi as a system engineer of Project G.U. for the CC Corporation. As a result Reiko becomes immersed in the Bansyoya File written by her brother Jun Bansyoya and the fonder of Project G.U. Throughout her journey Reiko investigates the project and visits the translator W.B. Yates, behind the former PC Hotoko, real name Mizuhara Haruka, to learn about The Epitaph of Twilight written in her brother's report. Much after with the information behind her Reiko Saeki as Pi later rescues Ryou Masaki's character Haseo and introduces him to Raven. When Atoli disappears Pi tracks her whereabouts to Morrigu Barrow. Along with Kuhn and Haseo, Pi travels to Outer Space to find Atoli where they unexpectedly face Tri Edge. Unfortunately before they can ask how to recover the Lost Ones Haseo uses his Avatar Skeith to use Data Drain against Tri Edge and Pi delivers the final blow with her Avatar The Avenger Tarvos, knuckles with spike like beasts' claws.
Soon after the incident however Atoli's Avatar is stolen and Pi is taken into the AIDA Server with the rest of The World. Reiko later escapes with everyone else using the AIDA Server Operations Folder and as time passes even schedules an appointment in Ikebukoro to meet with Ryo to discuss the condition of Atoli's player Chigusa Kasaka. Following this at Raven's @Home Pi restrains Endrance as the members of G.U. attempt to review what the avatars are when Yata presents the sixth Bansyoya File.
Later within A.D. 2017 inside the Akashic Records during the events of G.U. Trilogy, Pi while secretly working alongside Genius, infiltrates and serves as a member of G.U. a guild under Yata dedicated to the investigation of the AIDA phenomenon happening within the game, once more. After observing Haseo's battle with Tri Edge, a mysterious PK thought linked to AIDA she along with the other members of the organization Yata and Kuhn introduce Haseo to the Serpent of Lore where they explain to Haseo about the existence of Epitaph Users and their ability to summon beings known Avatars, a power strong enough to combat Tri Edge.
And as Haseo willing to do whatever it takes to get this power then follows. G.U. in the inter medium Pi along with Yata observes as Haseo continues to grow as a person, as he attempt to awaken to his Epitaph while also watching as he later meets the love of his life Atoli, another unawakened epitaph user, whose existence ironically actually jeopardizes Haseo's connection to Skeith as she calms the rage in his heart norn from the loss of his previous romance Shino of whom Tri Edge is rumored to have PK'ed and worrying Pi, who is also secrectly interested in Haseo's abilities about how at this rate he may never awaken as an Epitaph User, which Yata would then correct by explaining how if that were ever possible That Man would step in instead.
Sure enough later on sometime after Haseo gets in an argument with Atoli, the young Harvest Cleric finds her way to The Terrance at Isle of Kings Hy Brasail where she would then end up being approached by That Very Same Man, Ovan, an old friend of Haseo, whom, separate from G.U. has also been secretly watching everyone's growth as well and takes advantage of the situation.
And with Atoli looking for a way to get Haseo to look at her again, Ovan, for his own purposes tells Atoli about Haseo's previous attachments to Shino and explains that, if she wants Haseo to pay more attention to her, she can find a way to help Haseo, in an area in Outer Space, just beyond Morrigu Barrow Wall and also causing her to also disappear from the Serpent of Lore and subsequently The World itself.
Following up on the abnormality Pi and Yata use the system to track her last whereabouts to Morrigu Barrow Wall and after confirming her disappearance from the area recruit the remaining members of G.U. to investigate.
Once there the party Pi, Kuhn, and Haseo then travel through a Sign, a type of warp gate left by the mysterious Tri Edge Haseo to The Other Side of Morrigu Barrow Wall located in Outer Space where they arrive to find Atoli attempting to open a set of lockers in an effort to find a way to impress Haseo, who after hearing what she has to say starts to realize Atoli's feeling for him, but before any addition conversation is made the party are instead forced into a confrontation with Azure Flame Kite also known as Tri Edge, whom suddenly appear in the area as apart of his autonomous pursuit of AIDA, and as Haseo's presence then interferences with that pursuit drags the party down into Avatar Space where Azure Knight then transforms into the Guardian Deity of Azure Flames.
Faced with his nemesis once more this causes Haseo to finally begin awakening as an Epitaph User who from there then begins to transform into his Avatar Skeith, while Pi understanding everything convinces that is about to occur convices Kuhn and Atoli to gate back to Outer Space, for their safety.
After the battle Haseo once again reaches out to talk to Atoli however, the lockers behind her open and a series AIDA arms pierce Atoli's body instead causing her to fall in a coma. Quick to respond the party thenmitigate the situation by swiftly rushing Atoli's PC back to the Serpent of Lore where with help from Yata they discover her PC data is now falling apart as a result.
Realizing that this has may cause a more devastating outcome to her player than it appears. Yata proposes Haseo connect his PC data Atoli in order to enter her mind and save her consciousness before it's too late. Haseo agrees. And from there Pi and Yata use the Serpent of Lore to connect Haseo to enter Atoli's Inner World, causing him to enter a similar stasis.
During the proccess however unknown individual, Ovan, begins hacking the serpent of lore and as Haseo enters deeper into Atoli's Inner World and eventually her memories, the two suddenly surrounded by several black bubbles and as Yata orders Pi to place a tracer on them, the two are then subsequently abducted by AIDA.
From there as Haseo continues to attempt to free Atoli from inside her inner world Pi and Kuhn eventually manage to track the couple PC to the Inverted City Megan Fi where unexpectedly upon their arrival they are attacked by Ovan, the actual Tri Edge and the one controlling AIDA and are subsequently defeated.
Then much later on however after Haseo rescues from Atoli's own darkness. The two return to The World whereas Haseo emerges to find Ovan alongside the servered bodies of Pi and Kuhn and is soon to discover who after unlocking the seal on his arm PK's Atoli revealing him as the one behind everything and after allowing Haseo to wallow in his despair the leaves for to the Creator's Room as he invites Haseo to try and defeat him, whom after transforming into his B-st Form and being defeated once and returns in his Xth Form after conformed by Atoli's Spirit from inside his own Inner World and engages his opponent in one final battle, each activating their respective Avatar's as well and ending with Ovan guiding Haseo into activating The Rebirth, which he uses to reset the network, returning all the Lost Ones, including Shino, Pi, Kuhn, Atoli and, his little sister Ain with which as Ovan explains to he had manipulated everyone in order to save, before ultimately falling into a coma himself and being subsequently warped back to Megan Fi with everyone else.
However, with Ovan's Marty this leads Haseo grieves his lost as lead, leavinng Atoli who has recovered her status as a Lost One to activate her Avatar Innis and giving Haseo Wing's to go and recover Ovan's PC.
Haseo dives into Center of the System and after brief struggle with the consciousness of The World Aura, Haseo manages to pull Ovan from his self guilt saving him falling in coma as well placing an end to the situation with months later after Haseo reconciles his relationship with Shino and decides to continue his romantic relationship Atoli instead and Ovan reunites with Aina in Flowery Field somewhere in game.
Finally beyond that with the incident now pass then, everything ends as it secretly began. Pi now reappearing at her computer as her offline persona Reiko Saeki finishes her report with unknown individual, Genius, President of CC Corp, aka Durga Fima Shura and her employer with whom Reiko Saeki of The Akashic Records had been closely monitoring the situation as thus far, and after Genius going on to surmise/guesses that the will of heaven, the general outcome of the timeline, cannot be really denied, before then instructing Reiko, as she places down a special VR Scanner to pass the bar to, the ferrymen, Schicksal, an organization of hackers partially responsible for the deviation of the record in the first place, whom from that point there on move into their remaining plans to capture the current Aura of their own world circa A.D. 2019 - 2020, while Pi, within a different location within the Akasha Board would then thereon continue to work under Genius thereafter, and leadimg into the events of A.D. 2020.:
Reiko (Pi): "The menace has been dealt with. The situation is as predicted." ???: "I suppose it's not possible to resist the will of Heaven." ??? : "What are the people of Schicksal up to?" Reiko (Pi): "They have already moved on to the next phase." ???: "Give the oar to the ferryman." Reiko (Pi): "I'll do as you say."???: "Gather at Acheron, oh, Prisoners of Charon."
Being an Epitaph User, Pi can acquire a Lost Weapon during Volume 2 by collecting Adler's Keys: a rare pair of Gauntlets called "Stained Wing" (which is renamed to "Blinding Wing" once evolved to its final form), which adds Paralysis to normal attacks and increases critical hit damage by 25%.
Stat-wise, Pi has average attributes which are compensated by her very fast attack speed, which allows her to pressure her opponents at ease. However, she has the lowest magic defense in the game (tied with Tabby).
- The Gauntlets Pi starts out with are the Tiger Fist, a rare set of Gauntlets.
- Pi's name comes from the number π, which she believes represents herself: an indivisible and unbreakable woman.
- Pi's Japanese voice actress, Sanae Kobayashi, also does the voice of Mai Minase from .hack//Liminality.
- Pi's name was originally written as "Pai" in Japanese sources.
- Pi is 5'9" (175 cm) in height. According to Reiko, her measurements are 37-22-33.
- In the .hack//G.U. Prototype Trailer, early concept sketches had her being a Twin Blade, as well as wearing a less revealing attire.
- One of Pi's earlier concept sketches was later used in the G.U. games as one of the minor PCs Haseo can interact with.
