Yuka Takaoka is a Japanese woman who became widely known in 2019 following a violent incident that received intense media and social media attention. At the time, she was a 21-year-old bar hostess living in Tokyo’s Minato Ward. In May 2019, Takaoka stabbed her boyfriend, a male host from a nearby club, inside her apartment after allegedly finding evidence of his infidelity. The man survived the attack. What made the case go viral internationally was her calm demeanor afterward — she reportedly sat next to the victim, smoking a cigarette, waiting for the police while covered in blood. Photos taken by witnesses and circulating online contributed to her rapid notoriety. Recently, she has joined The ISG after meeting them and being obsessed.
