The 'Woman's Butt' series featuring Seri Mizuwaki. Seri has fair skin and an outstanding figure, but seems to struggle in acting. On the other hand, the content is irresistible for butt fetishists, and there are comments expressing regret for her potential as a top actress. While there is praise for her looks and high-quality content, there are also negative opinions about direction and eroticism. The emphasis on showcasing the butt in this work is perceived positively, but there are also expectations for other types of works.
