Haru Shibasaki, a female employee in her second year in SOD's proud Goods Division, is a serious woman with a dangerous gap between her appearance and her personality, and even holds black belts in karate and is a master in calligraphy. We were impressed by her courageous choice to analyze her own vagina as sample data for the development of a new onahole product. The entire work had its own unique visual direction, etc., and the story was well told without any sense of acting. As always, along with the overwhelming visuals, the highlights were the debut sex and the sex inside the sex office. This is the most shocking work I have seen since Masami Ichikawa, who is known for her cuteness, and I look forward to seeing more of her own work.
