Description
Hajime Shibata is a central figure in the first two seasons of the anime, introduced as a freelance journalist and a single father. Before becoming a freelancer, he was a respected reporter for a political and economic magazine. However, his career path took a morally ambiguous turn, as he came to rely on income obtained by blackmailing celebrities with the threat of exposing their scandals. This contradiction, between his investigative abilities and his methods, defines much of his character.

Hajime's personal history is marked by deep tragedy and guilt. He met his future wife, Ayumi, while both were journalism students. After years of harboring feelings for her, he finally asked her out, and they eventually married. The birth of their daughter, Tsugumi, was a happy event, but Hajime's dedication to his work led him to be frequently absent from home, leaving Ayumi feeling neglected. This marital strain culminated in a devastating discovery: while on a stakeout investigating a politician's affair, Hajime learned that the woman involved was his own wife. Blinded by rage and a sense of betrayal, he confronted Ayumi, ended their relationship, and forbade her from seeing Tsugumi. Shortly after, Ayumi died in a car accident near their home, an event Hajime witnessed. He was left with overwhelming guilt, blaming himself for the harsh words he spoke and believing his actions indirectly led to her death.

This guilt is the primary source of Hajime's most defining personality trait: a firm, almost desperate belief that vengeance is wrong. He is convinced that revenge only breeds more suffering and cannot bring true resolution. This principle drives his primary role in the story, which is to oppose the Hell Correspondence, a supernatural website that allows wronged individuals to send their tormentors to hell in exchange for their own souls. Upon learning of the website's existence, Hajime investigates it and discovers that his young daughter, Tsugumi, has a strange psychic link to Ai Enma, the Hell Girl herself. Through this connection, Tsugumi receives visions of Ai's activities, which Hajime uses to track down potential clients. He desperately tries to intervene in their lives, aiming to dissuade them from making a contract for revenge. His efforts are often fruitless, and his sometimes preachy or insensitive approach can alienate the very people he is trying to save. Despite his noble goal, he is largely a tragic failure hero, and this repeated failure slowly wears down his resolve.

The relationship between Hajime and his daughter, Tsugumi, is the emotional core of his character arc. As a single parent, he is caring and deeply attached to her, but their dynamic is unconventional; Tsugumi often calls him by his first name, "Hajime" or "Hajime-chan," reflecting a relationship that is more like that of a bickering but loving brother and sister rather than a traditional father and daughter. While Tsugumi is wise beyond her years, Hajime can be immature and bumbling in his parenting. Their conflicting views on Ai Enma's actions create friction, with Tsugumi feeling a degree of sympathy for the Hell Girl's work, which she perceives as a form of justice for the downtrodden. This conflict culminates when a family secret is revealed: Hajime and Tsugumi are distant relatives of Ai Enma, as they are direct descendants of Sentarou Shibata, Ai's childhood cousin who ultimately betrayed her 400 years prior. This ancestral sin makes them targets for Ai's lingering wrath.

The climax of the first season sees Hajime and Tsugumi confronting Ai. As punishment for his ancestor's betrayal, Ai traps Hajime in the Realm of Eternal Twilight and tries to goad Tsugumi into pulling the straw doll's red string, which would send her own father to hell. Ai forces Tsugumi to relive the circumstances of her mother's death, breaking down Hajime's emotional defenses and making him accept what he sees as his just punishment. However, in a pivotal moment, Tsugumi refuses to condemn him, declaring her love for him despite his flaws and his past mistakes. This act of forgiveness breaks the cycle of hatred and saves them both.

After this ordeal, Hajime's spirit seems broken. He gives up his mission to actively stop the Hell Correspondence, exhausted by his continuous and ineffective efforts. He channels his experiences into writing a biography titled "The True Hell Girl," intended as a record for future generations who might become entangled with the supernatural service. Shortly after completing this book, Hajime disappears entirely. His whereabouts become unknown even to Ai's supernatural attendants, leaving his ultimate fate a mystery. His daughter later implies they lost contact not long after her childhood, with his legacy living on solely through the book he left behind. His notable abilities are not supernatural but human: he is a tenacious and skilled investigator, capable of connecting dots and uncovering hidden truths, even if he cannot always change the tragic outcomes he uncovers.
