The complex protagonist of Tokyo Ghoul:re


Haise Sasaki, the protagonist of Tokyo Ghoul:re, is portrayed as a self-contained and good-natured individual. As a Ghoul Investigator, he embodies trustworthiness, loyalty, and dedication. While he maintains a serious attitude toward his work, Haise also exhibits a degree of mercy, believing that Investigators should not needlessly destroy Ghouls. Despite his authoritative role as mentor to the Quinx Squad, he respects and deeply cares for his colleagues, displaying a protective streak over them. Haise’s cooperative nature is evident, as he prefers to work with his team rather than accomplish goals alone. He also has a penchant for puns, as seen in his conversation with Akira Mado at the Naan restaurant, and often scratches the back of his head when he is contemplating or feeling uneasy.


Haise Sasaki’s background is deeply intertwined with the events of the Tokyo Ghoul series. He is a first-class ghoul investigator and a member of Team Mado, whose duties are overseen by Akira Mado and Kishou Arima. Haise’s true identity, however, is an important mystery. Formerly known as Ken Kaneki, a one-eyed ghoul, he underwent a transformation to assume the identity of Haise Sasaki. This change was the result of an intense operation that erased his memories and merged his ghoul powers with his human side. As a result, Haise Sasaki represents a new persona, unaware of his past and the truth about his ghoul nature.


Haise Sasaki’s appearance reflects his dual nature as a human and a ghoul. He has a youthful and handsome appearance, with short, white hair and captivating gray eyes. Standing 170 cm tall and weighing 58 kg, his physical attributes contribute to his overall enigmatic presence. Haise is often seen in the typical attire of a Ghoul Investigator, wearing a black suit with a white shirt and tie. His demeanor, while calm and professional, belies his inner conflict and complexity.


As an artificial one-eyed ghoul, Haise Sasaki possesses unique abilities that set him apart from both humans and ghouls. Combining his ghoul powers with his training as a ghoul investigator, he demonstrates exceptional combat skills and a deep understanding of ghoul behavior. Haise wields a quinque called the Yukimura 1/3 (Koukaku), a weapon specially forged from the kagune of a defeated ghoul. This quinque allows him to effectively engage in combat with ghouls. While Haise’s true potential lies in his repressed memories and ghoul side, his abilities as Haise Sasaki are formidable and crucial to his role as a ghoul investigator.


Haise Sasaki’s origins can be traced back to the events of the Tokyo Ghoul series. He was originally Ken Kaneki, a young man who became a ghoul after a fateful encounter. However, due to circumstances and the suppression of his memories, he underwent a transformation to become Haise Sasaki. This process involved the merging of his ghoul nature with his human side, resulting in a new persona. Haise’s origin is a complex amalgamation of his past experiences, the operation he underwent, and the subsequent struggle to reconcile his two identities.
