Matsuura is a 23-year-old male cameraman with brown hair and brown eyes, recently hired by Flower TV. Assigned to cover a hostage crisis alongside lead anchorwoman Etsuko Yamanobe, he initially admires her from afar. That admiration shatters when he witnesses her cold-blooded, sexually provocative behavior during the broadcast. Despite his shock, he becomes fascinated by her manipulation and control, often observing her actions through his camera lens.

Under Etsuko's direction during the hostage crisis, Matsuura films her orchestrating the hostage-taker's rape of victim Mayumi for broadcast. He reacts with visible surprise to Etsuko's explicit actions, including sudden nudity and on-site masturbation. He continues filming prolonged sexual assaults on Mayumi, including balcony scenes and the use of alcohol and aphrodisiacs supplied by Etsuko. His compliance extends to capturing Etsuko's staged interventions and her deployment of Molotov cocktails.

After the crisis, Etsuko treats Matsuura to a private dinner. She presents him with her soiled panties as a "gift," initiates sexual activity, and urinates into his mouth. When a waitress witnesses the act, Etsuko offers the waitress television exposure, implying Matsuura's continued involvement in her schemes. His professional standing improves among colleagues, reflecting his deepened entanglement in Etsuko's methods.
