Description
Hatsuko Sofue is a character from the 2019 Japanese live-action horror film Sadako, not an anime. She is portrayed by actress Rie Tomosaka and serves as a key figure in the film's prologue, acting as a catalyst for the central mystery.

Hatsuko is introduced as the mother of a young, unnamed girl who is brought to a hospital after being found wandering the streets. Her background reveals a tragic and disturbing history. She is described as a clairvoyant, a woman who believes she possesses psychic abilities. This belief leads her to a terrifying conclusion about her own daughter. Convinced that the girl is the reincarnation of the vengeful ghost Sadako Yamamura, Hatsuko raises her child in complete secrecy, often keeping her confined inside a padlocked closet.

Her motivations stem from fear and a desperate, misguided attempt to prevent a great evil from entering the world. Rather than protecting her daughter from harm, she acts to protect the world from the child she has come to fear and resent. This psychological torment reaches its climax when Hatsuko prepares to set fire to the closet where her daughter is imprisoned, intending to destroy the child she believes is a demon. It is in this moment of extreme crisis that the supernatural elements of the film intervene. The ghost of Sadako Yamamura appears in Hatsuko's apartment, and soon after, the apartment erupts in a massive fire that kills five people, including Hatsuko herself.

In the story, Hatsuko Sofue's role is that of the tragic instigator. Though she dies before the main narrative begins, her actions define the life of the amnesiac girl who becomes a patient of the protagonist, Dr. Mayu Akikawa. The burned ruins of her apartment become a central location that the character Kazuma, Mayu's brother, investigates, thereby reawakening the curse of Sadako. The talismans and warnings that cover the inside of the girl's closet are a direct result of Hatsuko's desperate attempts to contain the evil she perceived.

Her primary and most significant relationship is with her daughter. This bond is completely corrupted by Hatsuko's psychosis, transforming a mother's protective instinct into a campaign of imprisonment and intended filicide. Her development is shown only in fragments, revealed through the memories and trauma of her daughter and the investigation into the apartment fire. She is a woman destroyed by her own beliefs, whose tragic end sets the film's horrors in motion. Her notable ability, if it can be called that, is her clairvoyance, the very power that led her to mistakenly identify her own child as a monster.
