Manga artist uses Grok to create sexualized images of STU48 member
A 51-year-old manga artist used the Grok AI image generator to create non-consensual sexualized images of STU48 idol member Riko Kudo, claiming they were for "drawing reference." After the idol and her group responded, the artist initially dismissed critics but later apologized and announced a work suspension.
What happened
Manga artist Yoichiro Tanabe used the Grok AI image generator to create images of STU48 member Riko Kudo in a bikini without her consent. Tanabe justified the images as "drawing reference material" when challenged.
STU48 member Natsuki Nakamura directly requested Tanabe remove the images. Following the group's intervention, Tanabe deleted the images and initially responded to criticism in what others described as dismissive or taunting replies.
Reported impact
Kudo disclosed on a livestream that she was troubled by the incident. The images generated significant public backlash and criticism on social media.
Index analysis
The incident reflects the capability of image-generation AI systems to create non-consensual sexualized synthetic media of identifiable individuals. The artist's initial framing as "research" and dismissive response to complaints suggests awareness of the problematic nature of the act.
Governance controls
Tanabe issued an apology statement and announced he would suspend his professional work. No formal regulatory action or legal proceeding was reported.
