Appearance

Upon obtaining the power of an apostle, she grows wings.

Personality
In the beginning, Eri is portrayed as a calm and quiet girl that loves books. Later on, however, it is shown that she is very cunning and willing to take advantage of classmates for her own personal gain. She has a very deep obsession for Kouki to the point that she is willing to kill him in order to use 'soul bind' on him and make him her puppet and "boyfriend" forever.

While in her persona as the "Shy Girl", Eri is portrayed to be kind and compassionate to others, especially to her classmates of whom she considered to be her "friends", but due to her looks and tame personality is shown to be a tad bit shy, when dealing with them. However underneath this persona, Eri, in truth, despised pretending to being friends with her classmates and dislikes the fact that she needed to maintain this persona for long periods of time in order to stay in Kouki's good graces and truthfully wanted to slaughter them all in order to horde Kouki's attention all to herself. And upon being transported to Tortus, Eri was greatly delighted that her newfound powers now allowed her the chance of killing them all herself. however upon fully mastering her powers as a Necromancer however, Eri’s opinion on her former classmates had seemingly improved from seeing them as "Trash" to be thrown out, to "useful pawns (undead slaves)" to be used for her future plans. However even after her betrayal and eventual failure to kill them (except for Kondou, a classmate that she killed) due to Hajime's interference, Eri was none the less glad that she no longer had to "play house" with them any longer and was completely unrepentant in her choice of betraying them. Due to her obsession, Eri has has shown to have little remorse or hesitation in doing whatever she can in order to achieve her objectives, as seen where she didn't regret killing King Eliheid and the nobles in order to help her new allies in their invasion and fulfill her goal of obtaining Kouki until her plan was foiled by the raged costumed Hajime.

From her past experiences of her suffering in pain, anguish and agony from losing her birth father in a car accident, then facing the irrational hatred from her birth mother and then being physically abused by her step-father and being beaten to near death by her mother in rage for "ruining" her marriage "again", resulting in Eri having a miserable childhood that later affected her psychological/emotional development. Resulting in Eri's overall psychological mindset became severely warped due to her own tumultuous upbringing and lack of stable role models. Causing her to become exceptionally evil, manipulative, cruel, sadistic, selfish, traitorous and emotionally insecure when dealing with others that eventually lead to the development of her very warped sense of "love" and her obsessive tendencies.

This is seen where she came to conclude that the only way for her to truly be with someone is if she was the only person in that person's life that mattered. This was likely brought out from her mother's own selfish ideal of "love" and her own past tragedies that rendered her insecure and selfish when wanting to also be "loved" by some else. As seen where she would viciously try to kill each and everyone one of Kouki's friends in order to insure that his "love" would only remain with her no matter what and would even go as far as using her Necromancy to forcibly bind her to him to insure that he would always be "hers".

A clear example of Eri's emotional instability is seen when she began losing her control over Kouki due to Shizuku successfully getting through to him. Eri was shown to have immediately began suffering a nervous breakdown due to her "losing" him and falling into a crazed panic.

Due to her intelligence, Eri is highly manipulative and traitorous, even more than Daisuke Hiyama when going after what she wants and accomplishing her goals. She manipulated her classmates to become friends with her including the emotionally intelligent, Shizuku just so she would kill them in order to claim Kouki for herself. She also blackmailed Hiyama into helping her after noticing his sloppy attempt to kill Hajime and his gradual losing of footing in his attempts to deny involvement in order to twist it to her own advantage by threatening him that she would tell everyone else of his part in the "accident" unless he helps her. Later despite being collaborators together for their own mutual gain, Eri reveals that she never really saw Hiyama as a comrade or even collaborator but instead only considered Hiyama as a pawn to her that he will eventually outlive his usefulness and later discarded him by leaving him to death at the hands of Hajime without a second thought after witnessing Hiyama being pathetically weak and made no efforts or attempts to go rescue him from his death. Eri herself has little remorse for these actions and was fine being a traitor.

Due to her immense cruelty and sense of superiority, Eri is also shown to be highly abusive and remorseless torturer when she enslaves her undead minions and torturing the souls of the dead to force them to do her bidding like she did to Nia, Meld and Kondou. Eri is very sadistic when she enjoyed seeing her classmates suffers in despair, weep, wail, anguish and agony.

Due to Kaori and Shizuku being Kouki's childhood friends (despite of them being Hajime's lovers), Eri shown to be very envious who held a murderously jealousy towards them as she viewed them as her mortal enemies and wanted to kill them whom she referred them as "trashes" along with the rest of their classmates due to them being in her way of making Kouki as her boyfriend. When seeing Kaori was actually revived by Hajime, Eri's hatred towards her grew even worse. She never cared for Suzu when she doesn't considered the latter as her best friend but rather a nuisance. Though her fears for Hajime, she hates him for him continuing to ruin all of her plans.

Like Hiyama, Eri despite showing herself to be outwardly confident, is a coward when things start turning out of her advantage/favor. As seen where she showcased genuine fear and was terrified of her now mutated and murderous classmate, Hajime Nagumo after his murdering upon Cattleya. When Hajime arrives and ruined all of Eri's plans after the temporarily murder of Kaori, she begs him to spare her life so that she could revive Kaori as his undead slave in order to save herself as she betrayed Hiyama which only increased his anger further to the point of rage that consumed Hajime. She fears the worst when Hajime obliterates all of her undead slaves and kills Hiyama. After Hiyama's death, Eri thrown into greater fear when Hajime is willing to kill her for her failed attempts to turn Kaori into Hiyama's undead sex slave but got away with the help of Freid Bagwa.

After her transformation into a Apostle/Human Hybrid by Ehit, Eri was shown to have become completely fanatically loyal to the crazed false god, even more so upon him presenting Eri with Kouki as her "prize" for her continued faithful service to him and helping him complete his goals of obtaining a suitable physical vessel to contain his immense power.

Although unknown if this was the result of genuine loyalty or simply her mind being affected by Ehit's magic. Eri was noted to have become completely devoted to him and his goals and coupled with her original psychological instabilities, only made her all the more unhinged and murderous. While ignoring Suzu and Ryutarou when she focused on Kouki, she further descended to evil when she discarded her last shred of humanity inside of her heart. Eri was shown to prefer suicide over betraying Ehit, as seen during her final moments after being defeated by Suzu, where Eri instead committed suicide by detonating herself in a last ditch effort to kill her rather than go back with her to their classmates despite the latter's assurance that they would forgive her for her actions.

Much like Kouki, Eri is also clingy and deluded.

However despite her shamelessness and lack of guilt or regret in her actions on the surface, it was shown that Eri did at least on some level of her mind, did indeed possess some regret on how she lived her life and possessed a minuscule amount of guilt towards her actions. And during her final moments, she acknowledged that if she had meet and befriended Suzu first before becoming infatuated by Kouki upon meeting him, maybe she could have become a much better person than she was and things might have turned out much more differently for her.

Biography
When Eri was was 6 years old, her father died after saving from an in incoming car. This lead to her being abused both physically and mentally for years by her mother, due to her blaming Eri for his death. In spite of her mother's harsh treatment, Eri never reported her to the authorities; believing that she would eventually stop it and love her once more. However, when Eri was 11 years old, her mother started dating another man, much to her shock, and had moved with them. He was abusive and would constantly make sexual advances towards Eri at any opportunity he could. Eri did everything she could to avoid his attention, including cutting her hair short and acting more masculine. Despite her efforts, however, he still expressed his attraction towards Eri, and would eventually molest her one day while her mother was away at work. Eri managed to scream loud enough that the neighbors heard it and called the police once they saw what was happening to her. After he was arrested, rather than apologizing to Eri for bringing that man into their lives, Eri's mother instead accused her of seducing him. Realizing that the hardships she endured over the years had been for nothing, Eri decided the only thing for her would be to end her life. She snuck out of her home the next morning and headed to a nearby bridge that was above a river. As she was about to jump off the railing, she was suddenly approached the most popular boy in her school: Kouki Amanogawa. He had been out jogging that morning, and upon seeing Eri in such a dangerous position, he immediately helped her off the railing before asking what had happened to her. At first, the despondent Eri didn't say anything, but after Kouki repeatedly requested that she explain to him what had happened, Eri gave him a brief summary without getting too specific. After hearing her vague account, Kouki mistakenly came to the conclusion that Eri wanted to kill herself because she was scolded by her parents This prompted him to tell Eri that he would protect her. Hearing someone offer kind words to her for the first time in years convinced Eri not to kill herself, and she returned home.

When Eri went to school after her recent ordeal, she was approached by all the girls in her class, who after having avoided her for so long, suddenly wished to talk with her. She soon learned that this had been a result of Kouki's influence, and as a result, she developed a deep attraction towards him for the kindness he showed her. Several days later, Eri's mother was investigated by child welfare due to Eri's attempted suicide. However, Eri did not reveal her mother's abuse to them, and pretended to be a loving daughter. This was done in order to prevent her from going to a different school than Kouki if she had been separated from her mother. Eri's sudden change in attitude utterly shocked her mother, which soon led to Eri constantly manipulating her for years. Eventually, Eri moved out and lived on her own, while still receiving financial support from her mother. Once she had settled in, Eri then sought to start a relationship with Kouki. Unfortunately, she soon realized that Kouki's first act of kindness towards her had not been a romantic gesture, but rather a general sense of chivalry, and that he had treated all the girls he encountered the same way. This utterly infuriated Eri, and had since done everything she could to get closer to Kouki and get him to notice her more, all while becoming bitterly jealous of the girls that were always near him (particularly his childhood friends Shizuku Yaegashi and Kaori Shirasaki).

When Eri's classmate Hajime Nagumo was believed to have been killed in the labyrinth, Eri was among the students that resumed her regular training, despite having witnessed such a horrifying ordeal.

Her intelligence is shown when she invented an original Necromancy magic spell through personal research as well as choosing to betray her classmates and Heligh Kingdom to support the Demons as their spy for self-preservation as she already realized it is almost impossible to opposed the Demons who were supported by Ehit and his armies of five hundred Apostles.

Through clever manipulation, Eri recruited Daisuke Hiyama a fellow summoned Hero to assist her to kill most of the Knights of Heiligh Kingdom in order to reanimate them into her pawns which she planned to use in ambushing her classmates in a deadly trap. She also managed to tricked Shizuku into letting her guard down by using her friend and personal maid Nia who she has reanimated into her puppet to stabbed Shizuku in the back. Anticipating that Kouki could possibly escape, she used the reanimated Meld Loggins as a means to immobilize Kouki due to Kouki's attachment to Meld and Meld's superior sword skill in addition to applying a non-lethal poison to Kouki when she kissed him. Her plans would have succeed if not for Hajime's unexpected intervention.

Spirit Bind loses its effect on living beings if they are able to see past the illusion planted by the caster. "Does it hurt? Are you sad? Let me hear a pretty scream. Try to resist, curse me in your pain. You'll still be my little puppet. A pathetic little toy! Blessings to all deaths! Ridicule to every sorry soul!— Spirit Binding!"
