What is Rei Ayanami, and whose soul does she carry?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

Rei Ayanami is the enigmatic First Child of Neon Genesis Evangelion: an artificial girl grown from the salvaged body of Shinji's mother and made to hold the soul of an Angel. This ledger separates what the original series and The End of Evangelion establish about her nature and her soul from what fans dispute, what the story contradicts, and what it deliberately leaves open.

Established 5supported, uncontested

  • Established canon (Neon Genesis Evangelion, The End of Evangelion): Rei is an artificial human. Yui Ikari, Shinji's mother, was absorbed into Evangelion Unit-01 during a 2004 contact experiment, and Gendo's failed 'Salvage Operation' to restore her body instead produced the first Rei; the Red Cross Book states Rei was created from Yui's 'salvaged remains.' Ritsuko Akagi says only that Rei was born in a room deep inside NERV, and Naoko Akagi (Ritsuko's mother), who worked on the early Rei, murdered the first incarnation in 2010.▰▰▰▱▱ likely3 points

    • Gendo subsequently undertook a 'Salvage Operation' that attempted to recreate Yui's body and fix her soul back into it, but this failed, instead resulting in the creation of the first Rei Ayanami.Yui Ikari - Evangelion Wiki analysis
    • She is revealed to be a clone of his mother, Yui Ikari, and Lilith, an entity known as an Angel.Rei Ayanami - Wikipedia summary
  • The series establishes that Rei's body is Yui's but her soul is not: she is a human vessel for the soul of Lilith, the second Angel. Lilith is a Seed of Life, an entity equal to the first Angel Adam and the progenitor of the 'Lilin' (humanity); NERV keeps her crucified in its deepest vault, Terminal Dogma, and the LCL that fills the Eva entry plugs is Lilith's blood. In the director's cut of episode 24, Kaworu tells Rei that the two of them are human vessels for the souls of Adam and Lilith, respectively (see the sibling topic evangelion-what-the-angels-are).▰▰▱▱▱ likely3 points

  • Rei exists as a series of interchangeable bodies. Beneath a giant brain-like structure in the Dummy System room, NERV keeps an LCL tank holding dozens of soulless Rei clones that Ritsuko calls 'spare parts' and 'vessels'; when a Rei dies her soul is transferred to a fresh clone, and the three we follow are labelled Rei I, Rei II, and Rei III. Rei herself says 'if I die, I can be replaced.' The same clones double as the cores of the Dummy Plugs, the artificial pilot system NERV built from Rei's personal data.▰▰▱▱▱ likely3 points

  • Rei is the linchpin of the plans that drive the story. Because her body carries Lilith's soul, she is the component needed to trigger Third Impact and Instrumentality: in a scene in episode 25 Gendo tells Rei that the day of Third Impact is the day for which she was created. Gendo grooms her loyalty toward his own aim, reuniting with Yui, while SEELE and NERV deliberately let Lilith grow to the edge of readiness, so Rei's role in both schemes is central (see the sibling topics evangelion-nature-of-instrumentality and evangelion-end-of-eva-ending-meaning).▰▰▱▱▱ likely3 points

  • In The End of Evangelion, Gendo forces the Adam embryo grafted into his hand into Rei III, trying to fuse Adam with her to seize control of Lilith and reunite with Yui. Rei rejects him, merges instead with Lilith's body in Terminal Dogma, and becomes the colossal Rei/Adam/Lilith being through which Third Impact and Instrumentality proceed. When Shinji ultimately refuses Instrumentality, control passes to him, and Rei, having sided with his will, lets it end (see the sibling topic evangelion-end-of-eva-ending-meaning).▰▰▱▱▱ likely3 points

Disputed 3credible sources disagree

  • Exactly what constitutes 'Rei' is left contested. Canon splits her into a body cloned from Yui and a soul belonging to Lilith, and the Lilith page flatly calls her 'essentially Lilith itself'; yet across the series she visibly develops a self of her own, forming attachments and genuine emotion. Whether the real Rei is Yui's flesh, Lilith's soul, or the emerging person who chooses for herself is never resolved into one answer (see the sibling topic evangelion-what-the-angels-are).▰▰▱▱▱ likely3 points

  • How many Reis there are, and whether they are one person or many, is genuinely unsettled. The wiki insists the incarnations 'are the same character,' yet the destruction controller in episode 23 lists numbered clones 'from Rei 004 and upwards,' the tank holds dozens more, and each transfer muddies the previous one's memory. Rei I is described as 'heartless' and Rei III as having 'a shallower awareness of self,' so whether Rei I, II, and III are chapters of one life or separate individuals wearing the same face is left open to reading.▰▰▱▱▱ likely3 points

  • Later continuities rework Rei substantially, so her nature is not fixed across versions. In the Rebuild of Evangelion films (a separate, diverging continuity), the original Rei is lost and replaced in the third film by a memoryless clone from the 'Ayanami Series,' later revealed as Ayanami-Type No.006, who in the final film forges her own individuality apart from the earlier Rei, wants a name of her own, and dissolves when kept from LCL. In the Gakuen Datenroku spin-off manga, Rei is likewise a clone tied to Yui, revealed to be meant to take Yui's place in a world-sustaining Tree of Yggdrasil, who also defies Gendo.▰▰▱▱▱ likely3 points

Debunked 2refuted by the evidence

  • A popular fan reading holds that Rei simply IS Shinji's mother, Yui, reborn, carrying Yui's own soul. The confusion is understandable: Rei is grown from Yui's genetic material, resembles her, and Shinji senses his mother in her. But the series contradicts it. Rei's soul is Lilith's, not Yui's, and Yui's own soul stays inside Evangelion Unit-01 throughout the entire series, later drifting into space as Unit-01. Rei is Yui's clone in body only.Refuted byin which Kaworu goes on to say that he and Rei are human vessels for the souls of Adam and Lilith, respectively.refuted2 against3 points

  • Another common view, encouraged in-story by NERV treating her as expendable 'spare parts,' is that Rei is a soulless doll with no genuine feelings or will of her own. The narrative overturns this. The active Rei carries Lilith's soul (the tank clones, not she, are the soulless ones), she develops real emotion over the series to the point of crying, and at the climax she makes her own choice, betraying Gendo to go to Shinji rather than obey her maker.Refuted byShe knows she's expendable, but the thing is, she's still human so you can't do her totally catatonic.refuted2 against3 points

  • What Rei actually is on the inside, whether a genuine self hides behind the blank affect, is kept deliberately opaque. Character designer Yoshiyuki Sadamoto framed her expressionlessness as an open question, and director Hideaki Anno, who called Rei the character 'closest to my deep psyche,' admitted 'I don't really understand her.' Critics agree: IGN, ranking her among anime's most influential characters, still called her 'a mystery we never really solve.'▰▰▱▱▱ likelysummary-sourced3 points

  • Whether a single continuous 'Rei' survives the swapping of bodies is left unanswered. Supporting material says her soul transfers to a new clone each time she dies but that 'her memory becomes muddled with each transfer,' and in the manga the reborn Rei only half-remembers, wondering why she is alive again. The series never settles whether the Rei who wakes after a death is the same person or a fresh being inheriting a fading imprint.▰▰▱▱▱ likely2 points

    • it's hinted that the 'new' Rei still has some residual memories as she wonders to herself why she is alive again after returning to her quarters.Rei Ayanami - Evangelion Wiki analysis
  • Rei's final nature is left symbolic and open. In The End of Evangelion, spectral figures of Rei appear over the dying and throughout the NERV control room during Third Impact, seemingly apparitions created by Lilith, and Platinum-edition commentary floats that the bandaged girl Shinji glimpses may be 'the existence that gazes upon man.' The giant being she becomes has no official name, and what she is after merging with Lilith, and what her watching presence means, are questions the film raises and never closes (see the sibling topic evangelion-end-of-eva-ending-meaning).▰▰▱▱▱ likely3 points
