Appearance
Eri has short black hair that is kept in a tiny bob. She has brown eyes and is usually seen wearing glasses. After she discarded and broke her glasses, she shown a sinister expression to her face.

After 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 on 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 having to pretend 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. Upon fully mastering her powers as a Necromancer however, Eri 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 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.

From her past experiences of her suffering in pain, anguish and agony from losing her birth father from 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". Eri's overall psychological mindset became severely warped due to her own tumultuous upbringing and lack of stable role models. And as a result Eri has become overally manipulative, cruel, sadistic, selfish and emotionally insecure when dealing with other people that eventually lead to the development of her very warped sense of "love". As 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". And when she began losing her control over him, Eri immediately began suffering a nervous breakdown due to her now losing control over him as she began to despair that she was "losing" him.

Eri is highly manipulative when going after what she wants and accomplishing her goals. As seen when she blackmailed Daisuke 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 viewed Hiyama as just a pawn after he outlives his usefulness and betrayed him by leaving him to death at the hands of Hajime without a second thought.

Due to her immense cruelty, sense of mockery and superiority, Eri is also shown to be highly abusive 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.

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 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 shown into greater fear when Hajime is willing to kill her for her failed attempted 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, Eri was shown to prefer suicide over betraying him, 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.

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
Eri had a very tragic past where her father died saving her from a car accident and by protecting her, leading to her then receiving her mother's hatred after her father's death due to her blaming Eri for her father's death. Due to her mother having only loved her only because she is her husband's daughter and nothing more, and upon his death and her subsequent irrational hatred for her daughter due to holding her accountable, further made Eri's childhood difficult due to her now physically and emotionally abusing Eri that then possibly began the development of her warped perception of "Love". After her father's death, her mother remarried another man, but Eri's stepfather was later imprisoned by the police due to him physically abusing her and him being reported by Eri's neighbors who witnessed his abuse. This eventually lead to her mother once again blaming her daughter for again "ruining" her marriage and further amplified her already abundant hatred for her daughter that then lead her to then beat Eri to near death in rage, leading her to then also be imprisoned for abuse and battery by the police due the the commotion once again drawing the notice of their neighbors and reporting her. This incident along with the other tragedies of her life eventually left Eri with a very unstable psychological and emotional mindset that eventually became the root cause of her later issues in life.

However despite her initial bleak life that eventually lead her to develop a nihilistic/suicidal outlook of her life and her having to endure her mother's unjust abuse eventually lead her to seriously consider taking her own life to end her misery. However just as she was about to commit suicide, Eri while in middle school meet and soon became infatuated by Kouki Amanogawa due to his idealism,kindness and heroic sense of justice that moved her not to take her own life due to no longer wishing to endure her life under her abusive mother. Effectively giving her the will to continue on living for the sole reason of obtaining Kouki. Eventually leading her to soon become utterly obsessed and fixated with him and desire him to become "hers" and "hers" alone that even lead her to soon develop a deep sense of jealousy and hatred for Kouki's other friends due to her believing that they were getting in the way of making Kouki "hers". Eri in particular despised both Kaori Shirasaki and Shizuku Yaegashi due to them being incredibly popular and beautiful and them being Kouki's closest female friends. During this time,Eri even implied that she was secretly planning to get rid of the "trash" surrounding Kouki as well kill all of her classmates, but due to her at the time being powerless and not possessing the means to do it without getting caught, Eri instead decided to bid her time and wait for her chance to get rid of them all in the future. But upon being summoned by Ehit to Tortus and being given immense powers as a "hero", her plans for assassinating them was accelerated faster than she would expected thanks to her newfound power and the relative innocence of her classmates of not even suspecting her.

Allies

 * Noint - Noint was aware of Eri's plot to betray the Heiligh Kingdom but decided to cooperate with her due to Noint's master Ehit finding Eri's plans amusing. Eri was first scared of her and though that she would have to kill her but was grateful to her for her help as it speed up Eri's plans by months.
 * Freid Bagwa - Though they are allies, the two of them do not get along as Freid does not trust Eri. He finds her irritating as she is capable of avoiding his detection due to her dark magic. Despite this, the both of them are willing to cooperate with each other as Freid used his Metamorphosis magic to strengthen Eri's undead soldiers.
 * Garland - After Hajime killed Cattleya, Eri used the deceased demon woman's body to inform troops led by Freid of the situation of the Oscus Labyrinth has already been cleared and Cattleya died by Hajime's hands. She revealed to her classmates of her being Garland's spy and willing to betrayed them during the war in Heiligh to join Garland. After their defeats, they've retreated to Garland.
 * Ehit - Ehit finds Eri's plans amusing and considers her an interesting piece in his game. He decided to aid her plans by sending Noint to assist her. Eri is extremely grateful for his help and proudly declare that she has God's blessing on her side. Eri suggests kidnapping Myu and Remia to Ehit, as she knows that they will serve as good hostages for Hajime. Eri later assists Ehit in seizing Yue's body. After Ehit departs for the Holy Precincts after she seized Yue's body, he allowed Eri to accompany him to the Holy Precincts, stating that due to her help, he would grant her wish of claiming Kouki as her rightful "prize". After her defeated by Suzu, Eri refused to betrayed Ehit and attempted to commit suicide for her last loyalty for the false god.

Enemies

 * Kouki Amanogawa - Eri see's him as her savior and will do anything for him to be her's. After Aiko exposed the truth of Ehit as the evil god, Eri confirmed to Kouki as the reason why she betrayed him and her classmates. She tries to escape by dragging Kouki until she was surrounded by Hajime's harems. After her transformation, Eri's lust for Kouki has extended when she was granted by Ehit of have Kouki for herself as "prize" and boyfriend. Upon successfully "obtaining" him, Eri was shown to have become immensely clingy and delusional with Kouki and has shown to have little to no remorse in psychologically manipulating his fragile psyche in order to "keep" him.
 * Suzu Taniguchi - Even it's a lie, at some point she considers her a true friend. Though she mostly only sees her as a tool to get close to Kouki. Though she admitted if she meet Suzu before she meet Kouki, then things might have been different. After her defeat by Suzu, Eri committed suicide in a last ditch attempt to kill her.
 * Kaori Shirasaki - Eri hates her due to Kaori acting like it she takes being Kouki's friend granted and that it feels like a burden. After Hiyama temporarily killed Kaori, Eri was about to use "Blind Soul" to make Kaori as Hiyama's undead sex slave. But failed due to Hajime's arrival. While the raged consumed Hajime marched toward Eri, she cowardly begged to spare her life to revive Kaori as his slave which only angered him further. After revived by Hajime, Kaori has no grudge on Eri for her actions. When seeing Kaori was revived by Hajime, Eri's resentment for Kaori is continually increased even worse.
 * Shizuku Yaegashi - Eri hates her due to Shizuku acting like it she takes being Kouki's friend for granted and that it feels like a burden. She was about to kill her with her undead slave who was Shizuku's personal maid, Nia but failed due to Hajime's arrival.
 * Hajime Nagumo - It is unknown of how she feels for Hajime before his mutations, but Eri also want to kill Hajime with her other classmates due to him and the other classmates are being in her way for her desires to make Kouki her boyfriend. After witnessing he is still alive and gained inhuman strength and ruining her plans, she views him a monster who shows no hesitation killing even his own classmates, which makes her scared of him and his demonic strength. Prior to forming an alliance with Daisuke before she deserted him, Eri initially considers to work alongside Hajime before he falls into the abyss. When he arrived and got unstably consumed with rage from Kaori's temporarily death, Eri begged Hajime to spare her and she would revive Kaori as his slave which Hajime only shown his fury toward her for the worse. Hajime doesn't need Eri of her uses to him when he already have the spirit magic. When she send her slaves to attack him, Hajime easily destroyed her entire slaves. When Eri tried to kill Hajime with daggers, Hajime easily overpowered her. Before he is preparing to kill her, Hajime has tormented her to make her suffer to death slowly which is worse than the time Eri was suffered by her mother and stepfather. Hajime is willing to kill her for her betrayals disregarded of whatever motivations or reason has made her a traitor. She is terrified of Hajime worse when he murdered her former ally, Daisuke Hiyama (whom she'd betrayed) in coldblooded. After Daisuke's and the undead army's deaths and Eri's defeat, Hajime was willing to kill her for her betrayal of her failed attempted to turn Kaori Shirasaki into an undead sex slave for Daisuke, she got away with Freid Bagwa to Garland. Following her defection, Eri believe using Remia and Myu will be good hostages against Hajime but her plan was compromised and yet was ruined by Hajime again. After Eri captured Yue to presented her body to Ehit, she has angered Hajime for the last time as he will kill Eri for taking Yue from him, knowing that she has no resolves left within her at all. Unfortunately, Eri died by committing suicide.
 * Other Classmates - Eri pretended to be friends with her fellow classmates during their time together on earth and initially portrayed herself as a shy but nice girl on the surface. However in truth, She is evil and manipulative girl doesn't care for them and in fact actively secretly loathed each and everyone of them in secret due to them being in her "way" of making Kouki "hers" and even hinted that she was secretly plotting kill them all early on in Japan, but couldn't do it immediately due to her not yet possessing the means or power to do so and instead decided to bid her time plotting in secret. However this changed upon being summoned to Tortus and now being given immense power as a "Hero", greatly speeding up her plans to kill them all to rid them from her and Kouki and now only sees them as pawns that are to be killed and included in her corpse army. Her betrayal had a strong negative impact on all them as when she killed Reichi Kondou. After her transformation into an Apostle-Human Hybrid, Eri happily declared she would now massacre them herself in order to truly make Kouki "hers" alone and showed no signs of changing her mind despite Suzu attempts to get through to her. This is further cemented after her being defeated by Suzu, Eri showed to have no desire to return to them despite being told that they would forgive her and instead opted to kill herself by self detonation in a last ditch attempt to kill Suzu.
 * Hajime's Harem - Due to her betrayal, Eri made enemies with Hajime's lovers (Yue, Shea Haulia and Tio Klarus). When she tried to get away with injured Kouki, they've surrounded her as well knows that she is being outmatched by them. After her transformation, she captured Yue and gave her body to Ehit.
 * Daisuke Hiyama - One of her classmates and fellow traitor that she blackmails of his betrayal of letting Hajime to fall only for him returned as an indestructible monster, into working with her to get what they both want (Eri wants Kouki and Hiyama wants Kaori). However, like the rest of her classmates who are pawns to her, Eri viewed Hiyama as a mere pawn like the rest of them. After Hajime arrived, Eri betrayed Hiyama witnessing how weak and worthless he is when he outlived his usefulness for her attempted to make Kaori as Hajime's slave when their plan turn Kaori into Hiyama's slave was foiled when Hajime Nagumo arrived. After Hiyama was beaten and was left to die by Hajime in coldblooded, Eri doesn't even bothered of going back to Hiyama when she abandoned him due to him no longer having any form of strategic uses or values in Eri's future plans.

Weapons and Equipment

 * Long Staff: As a necromancer, Eri's main weapon is a long staff.
 * Daggers: Eri wield daggers as she attempted to kill Hajime only for the latter disarmed her.
 * Twin Greatswords: From her mutation as hybrid Apostle, Eri wield two broadswords.

Physical Abilities

 * Immense Physical Abilities - After undergoing the Apostle transformation process, Eri possesses all the physical abilities of the apostle. Her strength is more powerful than normal mana blessed humans. However her abilities are a bit inferior to true Apostle's or Kaori who possesses Noint's body and more inferior to Hajime Nagumo.
 * Genius Intellect - Eri has shown incredible, genius intelligence for her age, being superior to most of her classmates including her teacher Aiko. 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. She was also the only person who realized the fireball that caused Hajime to fall into the abyss was intentionally aimed at him and quickly figured out it was fired by Daisuke Hiyama, even correctly guessing his reason for it. But rather than sell him out right away, she chose to blackmail him to help her with her future plans. But when her plan to turn Kaori into Hiyama's sex slave failed due to Hajime's arrival, Eri has betrayed Hiyama in her attempt to make Kaori into Hajime's slave for her safety. Her intelligence holds inferiority to Hajime's own intelligence as her plans were always being foiled by him such as attempted to kill her classmates, making Kaori as Hiyama's sex slave and later trying to capture Remia and Myu as hostage.
 * Master Tactician - Eri has shown to be an extremely crafty psychological tactician and excellent manipulator, having managed to conceal her true personality of a cruel and twisted lunatic obsessed with Kouki, with feigned personality of gentle, quiet girl. Fooling all of her classmates including the extremely sharp Shizuku. She orchestrated a series of master plans to claimed Kouki for herself by killing most of her classmates, by secretly contacting the Demons to assist them in invading and destroying Heiligh Kingdom in exchange for killing her classmates who were the chosen heroes of Ehit and sparing her and Kouki. 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. In her attempted to convince Hajime into sparing her life to revive Kaori as his slave, she betrayed Hiyama for this attempt. However, her tactics of trying to capture both Remia and Myu to take them as hostages against Hajime was one step behind as her plan was compromised and foiled by Hajime when he captured and killed Alv.
 * Master Swordswoman - By using her necromancy powers, Eri was able to possess the knowledge of Meld Loggins, the best swordsman in the Heiligh Kingdom thus obtaining his knowledge in swordsmanship, thus becoming proficient in using a single sword in battle. In her attempted to kill Hajime, her swordsmanship for daggers were paled as the latter disarmed her. After her transformation as an Apostle, Eri gained swordsmanship of an apostle with wielding two great swords but outmatched by actual Apostles or Kaori (while resided Noint's body).

Magical Abilities

 * Immense Mana - Being a Necromancer and one of Ehit's summoned heroes, Eri has more mana when compared to other people of Tortus. By continuously training in secret, she was able to increase her mana capacity. After undergoing the Apostle transformation process, Eri gains the immense mana of one of God's Apostles, allowing her to perform her spells on larger scales and at higher levels than before.
 * Magic Master - Eri has one of the highest magic aptitudes among Ehit's chosen heroes, particularly in Dark attribute Magic due her Job Class as a Necromancer. Her already high aptitude was increased by her secret training after which she was able to control up to 500 reanimated corpses as puppets by tormenting the souls of the dead to do her bidding. Her skill in necromancy magic allowed her to develop a spell that was a degraded version of Age of Gods magic. After obtaining her Apostle powers, her magical abilities improved dramatically, being able to temporarily disable Yue with her dark magic.

However, Suzu noticed that she cannot perfectly utilize the power of the Apostle's or trace back their experience as Suzu noted that while she can block Eri's Disintegration bombardment, she cannot block Kaori's Disintegration bombardment.

Spells/Attacks

 * Spirit Binding - Eri's original Necromancy spell which allows her to tear out a soul fragment containing memories, thoughts and personality of a dead person from their spirit and bind it to their corpse to reanimate it. This magic is only usable for a short time after a person has died. Due to it being a crude form of spirit magic, Eri can only rip out fragments of her victims's souls instead of controlling it entirely, leaving her victims in a mental state of Hollowness. After being enhanced with Apostle powers, she can even do Spirit Binding on living being. However, she can only guide the targets consciousness into believing a what the caster says. Spirit Bind loses it's effect on living beings if they are able to see past the illusion planted by the caster.

 * Mind Slip - A dark attribute magic that temporarily sealed the target's memory for a few seconds until the current time.

Quotes

 * (To her classmates): "Fufu, I’m so glad we all came to this world. Getting rid of all of you would have been difficult back in Japan. Which is why, of course, I can’t let you guys win this war and go back home. Because Kouki-kun’s going to spend the rest of his days here, with me. Forever."
 * (To Hajime Nagumo and his harems): Ahaha, give it up! She's already dead. I never thought you guys would show up here... Well, I should have expected it since Kaori was here and all... Looks like Hiyama's outlived his usefulness, so how about I give Kaori to you instead? If you promise not to fight me, I'll use my magic bring her back. She won't really come back to life, but at least she'll still look pretty. It's better than letting her rot, I imagine. What do you say?"
 * (To Hajime Nagumo after ruined her plans): "Why'd this monster have to show up and ruined all my plan?!"
 * (To Hajime Nagumo): Wait, hold on. Let's talk things through, Nagumo. Look at all these soldiers. They look like they're practically alive, don't they? It's unfortunate Kaori died, but I can at least make her like them. Besides, this way you'll be able to do whatever you want with her. So if you don't want her to rot away, you'll need to keep me ali-"
 * (Eri expressed fear of Hajime): "I'm going to die."
 * (To her undead soldiers): Tch... Get him!
