Description
Kyōko Himekawa is a supporting character in the manga and anime series MARRIAGETOXIN. She is an art thief with a unique moral code, specializing in recovering stolen artwork and returning it to its rightful owners. Her birthday is July 14, and her blood type is O.

In terms of personality, Kyōko is highly sociable and gets along with nearly everyone she meets. Despite her friendly and easygoing demeanor, she is a private person who rarely opens up about her personal feelings or her past. She is described as bold, straightforward, and possessing a strong inner core. Her appearance is characterized by short orange hair that reaches her nape, blue eyes, and a tomboyish style that often includes a jacket, sneakers, and shark tooth earrings.

Kyōko has a profound and enthusiastic love for sharks, which defines much of her personal life. She collects all things related to sharks and holds an incredibly high opinion of any movie that features one. Beyond her work as an art thief, she holds a variety of other jobs, including working as a hostess at a family restaurant, a lifeguard, a mover, and a driver of a yakitori food truck. She is aware that many customers and coworkers are secretly fans of hers but strives not to let the attention affect her.

Kyōko's primary motivation stems from her past. She was adopted at a young age by an art collector who was himself a thief, and she decided to dedicate herself to returning the stolen artworks to their legitimate owners. This mission drives her actions within the underworld. In the story, she is introduced as one of the first potential love interests for the protagonist, Gero, and is referred to as his first "candidate" in his marriage-hunting mission. Her path crosses with Gero and the marriage swindler Mei Kinosaki during a heist on a luxury cruise ship, where a high-profile painting theft occurs.

Key relationships in her life include her connection to the protagonist, Gero, whom she meets during his search for a wife. In the course of her work, she also utilizes underworld connections, such as hiring an expert known as "the Hamster" to assist her on a mission. Her backstory is also tied to her adoptive father, an art collector whose actions inspired her current path. Kyōko's development in the narrative shows her facing personal struggles, such as being fired from a part-time job and feeling lonely, yet she remains unwavering in her commitment to her cause, continuing her work until all stolen art is returned.

One of Kyōko's most notable abilities is a form of sixth sense that allows her to see strong emotions that have been imbued in objects, particularly works of art. This unique perception is central to her effectiveness as an art thief who seeks justice rather than profit. She is also described as brave, capable of handling trouble herself, and physically adept, often wearing a diving suit underneath her clothes for her underwater operations. Her resourcefulness is further demonstrated by her proficiency in various odd jobs, showcasing a versatile and resilient nature.
