Detective Todoroki, whose full name is Wataru Todoroki, is a character who originated in the Cutie Honey 90s manga as a major supporting figure. He is a young man with short black hair and dark eyes, typically dressed in a suit and tie complemented by a trench coat, fitting his role as a police detective. His professional background establishes him as a decorated officer dedicated to maintaining public order, and he initially approaches his work with a healthy skepticism, investigating suspicious entities including the influential Hayami Group. Before encountering the supernatural elements of his world, he had a tough time believing in the existence of Cutie Honey and the criminal organization Panther Claw.

Personality wise, Todoroki is portrayed as a competent and dedicated detective who uses considerable powers of deduction at crime scenes to piece together events. However, he also has a notable and rather perverted side, being highly attracted to young women such as Honey Kisaragi or Seiko Hayami, with one account even mentioning him taking Seikos panties when she was not looking. This combination of professional diligence and personal lecherousness defines much of his character. After a traumatic encounter where he was attacked by Tarantula Panther and rescued by Honey, his perspective shifts dramatically, and he becomes a willing supporter of her cause, deciding to help her with his skills in any way he can.

In the narrative of the Cutie Honey 90s manga, Todoroki is initially suspicious of Honey and the Hayami Group when his superior directs him there for answers about a series of murders and heists. He is easily attracted to Honeys appearance but doubts her explanation of Panther Claw. Following his rescue from Tarantula Panther, he becomes a key ally, using his deductive abilities to aid Honey, such as deducing the culprit of a murder at a film studio. He assists Honey in the final battle against the antagonist Sister Jill. A curious and notable aspect of his development is that after this battle, he somehow loses his memories of both Honey and Panther Claw, reverting to a state of ignorance about the extraordinary events he participated in.

This memory loss affects his role in later iterations, such as in Cutey Honey Tennyo Densetsu. In that continuity, he appears as a recurring character who does not recall any of the previous events of his life. The police are having difficulty with recent cases, so Todoroki seeks help from private investigator Seiko Hayami and her assistant. In this version, he serves mostly as an informant and occasional backup, all while being strongly attracted to Seiko and her sensuality. The character of Todoroki has become a semi-staple in the Cutie Honey franchise, with different versions appearing across various series. For instance, in Cutie Honey a Go Go, a version of Todoroki exists who is a diligent young police inspector and the long-suffering assistant to Natsuko Aki, though this version is described as polite and mild-mannered, lacking the more perverted traits of his predecessor and being constantly teased by his superior.

Regarding his abilities, despite his sometimes bumbling or perverted demeanor, Todoroki is a competent and skilled detective. He is well-educated, and beyond his investigative prowess, he is also quite capable with high-performance firearms, showing his skill with weapons multiple times throughout the story. His role is consistently that of a human anchor in a world of androids and monsters, using conventional police methods to support the super-powered Cutie Honey.
