Eri

Eri is the granddaughter of the Shie Hassaikai's Boss.^[3] She was the key source of Kai Chisaki's operation to manufacture the Quirk-Destroying Drug via her Quirk, Rewind, and had been living at the U.A. dormitories since she was rescued.

Following the Final War, Eri's guardianship was transferred from her grandfather to Mandalay, and she now lives with her and Kota Izumi.^[4] Eight years afterward, Eri is now a middle school student who dreams of being a musician, while beginning her street performing career under Kyoka Jiro's tutoring.^[2][4]

Appearance#

Eri is a small girl with bluish, off-white hair, messy and unkempt, which is parted in the middle of her forehead, almost reaching down to her waist. She has very wide, innocent-looking eyes, which are bright red in color. Poking out from the right side of her forehead is a small, brown horn, which grows larger when her Quirk is activated.

In her first appearance, she's wearing a plain, short-sleeved dress, which is a dirty, pale tan color. Bandages are wrapped around both her arms and legs, stopping at her wrists and ankles, underneath which she is shown to have numerous scars.

After she's taken in by U.A., Eri's outfit is changed to a white dress shirt with a frilled collar and a plain red pinafore with two large, golden buttons on either side of her chest. Under this, she wears gray tights and a large set of tan boots, and a small dark red messenger bag with the strap sitting over her right shoulder, and 2 little flowers decorating one of its sides. Her hair also looks to be better cared for, appearing straighter and neater than it was during her time with the Shie Hassaikai.

Near the end of the Final War, she willingly ripped off a piece of her horn, with the help of Ectoplasm, and gave it to Shota Aizawa to help save Izuku Midoriya.

Eight years after the Final War, Eri's horn has healed and grown longer. She is seen wearing a white long-sleeved seifuku like her peers, both the skirt, collar, and wrist red with a double white trim, paired with a blue scarf, dark brown leggings, and brown dress shoes. She also carries around a black bag for a guitar.^[2]

Personality#

Because her mother disowned her after she accidentally made her father disappear with her Quirk and the experiments she was subjected to by Kai Chisaki, Eri became a fearful and secluded girl, without anyone showing affection to her in her life. Apparently, Izuku Midoriya's touch was the first time she ever felt kindness, which overwhelmed Eri and brought tears to her eyes. When murderous intentions are directed towards her, she neither screams nor cries but simply remains silent in knowing that she has no choice but to accept whatever will happen to her. Although Eri's attempts at resisting and escaping her abuse slowly diminished, she still made numerous attempts to escape her captors, despite knowing nobody she could turn to.

Eri is, however, willing to let herself go with Kai in order to protect those who help her, as she feels guilt over other people getting hurt in order to rescue her. This is a result of Kai manipulating Eri into believing that her existence and Quirk are only meant to harm others. As such, Eri feels strong and horrible guilt and does not want other people to die because of her.

Unfortunately, after her rescue, Eri still psychologically suffered from Kai's influence, as she was unable to smile due to having no experience of being happy. However, this changed, thanks to the events of the U.A. School Festival, where Eri finally smiled for the first time and expressed her joy at Class 1-A's band performance. Following this event, Eri becomes more cheerful around those she is familiar with and slowly accustoms to her new life at U.A.

At first, Eri still felt negative about her Quirk and was apologetic to her caregivers at U.A. when believing that it was causing them trouble. After Izuku encouraged her that Rewind could also be used for good, however, Eri develops a more positive outlook, which encourages her to do her best with her Quirk training. Even so, Eri was still scared of the deadliness of her Quirk due to remembering how it vanished her father out of existence. However, she becomes inspired by Izuku and Mirio Togata, seeing how both young men continue to train and do their best no matter how bad things get, overcoming the fear of her Quirk and using it to heal a kitten's wounded leg.^[5]

This improvement is further shown when she is able to restore Mirio's Permeation, telling the latter not to be sorry, and that she had been training Rewind to bring his power back as a means of thanking him while tearing up in happiness. Due to her previous upbringing and isolation, Eri is still rather unfamiliar with many regular concepts and day-to-day things. This includes holidays, as she mixed up Halloween, Setsubun and Easter with Christmas.

After seeing Class A's performance at the festival, she was completely inspired by one of the class members; Kyoka Jiro, who was the lead singer in the band, and wanted to sing like her, much to Kyoka's delight. She wants to sing to the entire class after seeing them on stage, and when the war ended, Eri gets to perform, just as she wished, with Kyoka being her lead guitarist. As time passes, Eri continues to pursue her dream of becoming a singer, with Kyoka giving her music lessons on her days off from Hero work.

Eight years after the Final War, Eri's mentality has improved for the better, and she is seen enjoying regular school activities, such as music, with her peers. Upon visiting U.A. and greeting Shota and Hizashi Yamada, Eri has shown to have grown into a kind-hearted and thoughtful young lady, thanking Mandalay and Kota for adopting her as she brings the teachers some treats made by the former. While she still thinks Izuku and Mirio are awesome and wants to spend more time with them, she does not wish to take advantage of their fame. Upon seeing a news report of Izuku, Katsuki Bakugo, and Shoto Todoroki in action, Eri is amazed as she watches Izuku's triumphant return to being a Hero, something that inspires her to do her best as well.^[4]

Abilities#

Overall Abilities: Despite her powerful Quirk, Eri use to be very inexperienced when she was at her young age and previous isolation, especially after being subjected through various experiments by Overhaul throughout her childhood, having never been educated about her Quirk and not knowing how to use or control it. During the Shie Hassaikai Raid, Eri begins to grasp the abilities of Rewind when she split Overhaul and Shin Nemoto apart. Later, during Izuku's fight with Overhaul, she had accumulated enough energy to allow Izuku to reach Full Cowl - 100%, but wasn't able to control her power output as she continued to rewind Izuku before the timely arrival of Shota Aizawa, who used Erasure to prevent her Quirk from killing Izuku. Afterwards, Eri gained a fever and fell unconscious.

After being rescued by Izuku and Mirio, and moving into U.A. High School, the faculty have helped Eri train her power. Using small ounces of energy, she managed to regenerate the limbs of bugs and lizards. Eventually, she gained enough control over Rewind to restore Mirio's Permeation Quirk the day before the Paranormal Liberation War began.^[6]

• Musical Skill: During the Final War, Eri reveals that she has been inspired by Class 1-A's performance during the School Festival to become a musician. As she is seen carrying a guitar following the eight-year timeskip and is revealed to have been taught by the musically talented Kyoka Jiro, this implies that Eri has gained some proficiency at singing and playing instruments.^[4]

Quirk#

Rewind: Eri's Quirk allows her to reverse a living body back to a previous state, allowing her to make her target physically younger, heal injuries, and undo bodily modifications. As shown by when her Quirk first manifested and accidentally affected her father, she can even rewind someone's body to a point before they existed, erasing them completely.^[3]

The source of her Quirk's power is located in the horn on her head, and the size of the horn dictates the strength of her power. As Neito Monoma revealed when he copied her Quirk, it is also an accumulation-type Quirk, which means the power it emits has to build up over a period of time before becoming usable.

As a result of her Quirk mutating her body, Eri's blood is able to attack an individual's Quirk and stop its activation by reversing the target's evolution before the point of the Quirk phenomenon, a fact that became the crux of Kai Chisaki's ambitions as he supplied the creation of the Quirk-Destroying Drug by using his own Quirk to viscerally deconstruct her, gather quantities of her blood, and then quickly reconstruct her.

It was suggested by Eraser Head that her Quirk can even rewind the bodies of those who have lost their Quirks and restore them. However, Eraser Head indicated that Rewind only works on people, not on things, which means that it's not something that can be easily trained. This also means Eri cannot use her Quirk on an immaterial concept like time, as it is not a living thing.^[7]

In order to help Izuku during the Final War, Eri snaps off her own horn, potentially damaging her Quirk as a result. Once detached, Eri's horn worked as her Quirk normally does, though only able to use as much energy that she had stored up within her, which was about two to three minutes worth; this was able to rewind Izuku's arms back.^[8]

As of the epilogue, Eri's Quirk has presumably healed along with her horn, though it isn't seen in use.

Trivia#

• Eri's name is composed of two characters: "break" from "destroy" or "necrosis" and "reason, logic" from "reason".
• Putting the two characters together can translate as "destruction" or "reason of destruction" with the original words together, noting how her Quirk was used to make Quirk-Destroying Drugs and how it can potentially destroy living things by rewinding them out of existence. Her name also alludes to how her Quirk "breaks logic" by its very nature, being referred to as a mutation since it does not resemble any Quirk from either side of her family and very few people understand how it works.
• Hypothetically, Eri's name can be scripted just like "laugh, smile" from "smile", or "smile", and "advantage" from "profit", a more positive name tied to her soon smiling nature.
• According to Eri's Volume 19 profile:
• Her favorite fruit are apples.
• She shares her liking of apples with Fumikage Tokoyami and Pony Tsunotori.
• Eri's main outfit following her rescue was chosen by her nurse after Shota bought her an unfashionable sweater featuring cat emotes.
• Kohei Horikoshi admits to finding Eri a hard character to draw and portray, with one of her initial sketches being scrapped as she looked a bit too prepared for the oncoming Shie Hassaikai Raid.
• Eri has many similarities with Tomura Shigaraki as a child:
• Both of them have light blue/white hair and red eyes.
• Both children manifested unique and dangerous Quirks that ended up killing their relatives, Eri's father and Tomura's entire family.
• Eri's Rewind is stated to be a unique variant different to that of her lineage. Tomura's Decay was initially thought to be the same, before it was later revealed to be an artificial Quirk given to him by All For One.
• Both had caring grandparents and conversely, Eri's maternal grandfather was a Yakuza boss while Tomura's paternal grandmother was a Pro Hero.
• Both children were abused, Eri by her foster father, Kai, and Tomura by his actual father, Kotaro Shimura.
• Both Eri and Tomura were taken in by villains, Overhaul and All For One, respectively. The only difference is that Eri was subjected to torture at the hands of Overhaul and was eventually rescued by a hero while All For One treated Tomura with care, albeit for his own motives, and raised him to become a murderous villain himself.
• Additionally, both Overhaul and All For One are responsible for getting rid of their grandparents with Overhaul having forced Eri's grandfather into a coma while All For One killed Tomura's grandmother in battle.
• Eri's English voice actress, Emily Neves, also voices Sirius.
