Mayu Ikeda

was a ten-year-old girl who died in a fire she caused. Trying to worry her mother, she had hidden in a closet and was unable to get out. Mistakenly thinking that her mother did not love her, she became a vengeful ghost attempting to kill her little brother.

History
When Mrs. Ikeda did not come to the school's open house, Mayu returned home angry and hateful. Her mother explained she was unable to come because Mayu's younger brother Satoru was sick. Feeling envious of her mother's constant attention towards her brother, she runs away but comes back later. After returning to the apartment they live in, Mayu puts her scarf over a radiator (something her mother told her not to do) and hides in the closet to get back at her mother for perceiving and for ignoring her, telling a still awake Satoru not to tell Mrs. Ikeda that she was there. The scarf catches fire and leads to the apartment catching fire as well. Mrs. Ikeda comes back from shopping and finds her apartment on fire. She rushes in to save Satoru and gets out safely but unfortunately did not know Mayu was still hiding in the closet. By the time the firefighters found Mayu, it was too late; she had either burned to death or died of asphyxation.

However, this was not the end for Mayu. Thinking that her mother had deliberately left her to die in the fire, Mayu's soul was not at peace as she was filled with hatred and resentment towards her family. Thus Mayu could not pass on to the afterlife and became a vengeful ghost, intent on killing Satoru who she thought her mother loved more than her, as what she believes to be revenge on her mother for (unknowingly) leaving her to die.

Mayu's existence as a ghost was maintained by a youkai known as the Soul Piper, who looks after the souls of dead children until they can either accept their deaths or are to be sent to Hell if the child does wrong. It's eyes are usually closed, but every time Mayu committed a harmful act against her mother, brother or anyone, the Piper's eye opened slowly, symbolizing Mayu drawing closer to the point of no return.

Because of the fire, Satoru fell into a coma and remained in this state for about a year. He also happened to be friends with Sōta, Kagome's little brother. Sōta, with Kagome visits Satoru in the hospital. Kagome has the ability to see Mayu in her spirit form, and finds her with the Soul Piper. She goes to Myōga to learn of the Soul Piper and returns to attempt saving Mayu's soul. After learning the truth about what really happened during the fire from Mayu's mother, the two of them catch Mayu as she's making yet another attempt to kill Satoru. She knocks her mother unconscious but Kagome is able to get through to Mayu and she realizes that she was responsible for the fire. But claiming she still hates them both, Mayu tries to kill Satoru again but he is saved by Inuyasha for his just-in-time arrival.

Before Mayu can make another action, the Soul Piper appears behind her with its eyes fully open, signifying that Mayu is doomed to Hell because of all her hateful actions. Mayu protests as the Soul Piper wraps her up in chains, takes her away back to her apartment where she died, and subjects her to an illusion of how she died in the fire. As Mayu thinks on how it happened Kagome soon arrives and tries to get Mayu to come with her but Mayu brushes her off not wanting her help.

But moments later, a portal to Hell opens up in the floor and the chain still attached to Mayu's arm pulls her down into it, much to her terror. Kagome barely manages to grab Mayu's other arm as Mayu holds on desperately, but the Soul Piper adds more force to the pull making it all too clear that it's only a matter of time before Mayu is dragged into Hell.

To save Mayu from Hell, Kagome tells Mayu she can't have it end like this and urges her to make up with her mother before she passes on for good. The desperate Mayu asks Kagome if her mom is still angry, and Kagome tells her that her mother does love her and always has, which cause Mayu to think back to all the happy times she had with her mother and realizes it's true. Driven to tears, Mayu pleaded desperately for a chance to apologize. Seeing Mayu's change of heart, the Soul Piper decide to give Mayu a chance to atone and changed his judgement on her soul. Her chains break as the portal disappears, Mayu was spared from Hell.

The next day, Mayu's mother returns to her old apartment and is confronted by the no longer angry Mayu's soul. Mayu apologizes to her and asks for her mother's forgiveness. Her mother lovingly forgives Mayu and she says her final goodbye. Though still grief-stricken, Mrs. Ikeda is now more content having reconciled with her daughter. Having made up with her mother, Mayu's soul was finally at peace.

Having atoned for her actions, Mayu was now able to ascend to the heavens. As a bonus, the Soul Piper allowed her to remain for one more week until her brother came home from the hospital. At this time, Mayu visited Kagome at her home wearing a beautiful goldfish yukata her mother had made her. Mayu thanks Kagome for everything, and finally moves on.

As Kagome watches as Mayu departs with the Soul Piper, she thinks to herself on how Mayu was never an evil spirit as Myōga had claimed but merely ordinary little girl who loves her mother more than anything.

Personality
When Mayu is alive, she is shown to constantly argue with her mother due to the jealousy she feels toward her brother Satoru. After her death, she becomes vengeful towards her brother and wishes to kill him. Her jealously continues to grow to the point that she also attacks other children. Deep down though, Mayu loves her mother very much and only acts out of vengeance because she wants her mother to pay more attention to her. She becomes much kinder after wishing to make peace with her mother before moving on to the afterlife.

Physical description
Mayu appears as a young girl with short black hair that is tied into twin-tails. She strongly resembles her mother and brother.

Outfit
The outfit Mayu wears when she dies consists of a red winder coat, a light blue top with large yellow flowers on it, a dark blue skirt, and long grey socks. She also has a pair of hair bands with red balls on them.

After making up with her mother, Mayu wears a blue yukata with a goldfish pattern on it and a large yellow obi sash around her waist, which her mother made for her.

Powers & Abilities
Although a human, as a ghost, Mayu gains a variety of powers akin to a poltergeist. Her powers appears to be strongly tied to her emotions.
 * Telekinesis: Mayu can move and manipulate objects of seemingly any size depending on her emotional state.
 * Pyrokinesis: When angry, Mayu can summon flames, although they are only maintained by her presence.
 * Teleportation: Mayu can vanish and appear anywhere she chose.
 * Flight: As a spirit, Mayu is unaffected by the physical world and thus immune to gravity, she can fly and hover in mid-air.
 * Invisibility: Being a ghost, Mayu can not be seen by the living, however, people with spiritual powers, like Kagome, are able to see her. Inuyasha and Mayu's mother are also capable of seeing her.

Relationships
Mrs. Ikeda loved both of her children dearly. She always tended to their needs and was a very kind, loving mother to both of them. Mayu loved her mother very much, but was always angry of the time that she spent tending to her sickly brother Satoru. This caused the two of them to get into arguments. Mayu believed that Mrs. Ikeda abandoned her to her fate, and became extremely bitter toward her as a ghost. Her mother actually didn't know that she was trapped in the fire and was heartbroken after learning that, but was relieved when they finally made up.
 * Mrs. Ikeda

Mayu was very jealous of Satoru since their mother constantly tended to him when he was sick, thus she felt that he was their mother's favorite child. Thinking that the lady abandoned her to save Satoru when she died, Mayu became vengeful and would try to kill him as a ghost. She gave up her pursuit of vengeance after she was able to make peace with her mother and realised that she had been wrong.
 * Satoru

Satoru himself cared a lot for Mayu, and was very worried for her sake. The first things he did as he woke up was telling his mom that his sister was in danger (not knowing that she was dead already), and begging her to save Mayu.

Manga vs. Anime

 * In the manga, Mayu attacks Kagome and Sōta near her old apartment by telekinetically throwing a drain pipe toward Kagome. In the anime, Mayu telekinetically pulls up a nearby tree and bushes in midair and causes them to fall all around Kagome and Sōta.
 * In the manga, Kagome hugs Mayu after rescuing her soul from being pulled into Hell.

Trivia

 * In the Korean dub Mayu was renamed to Yoo-jin.
