The ace of the swimming club, Kiyohara Miyuu, who is expected to participate in the Inter-High, struggles with complex feelings about her rapidly growing breasts, leading to the release of this shocking work that can be described as almost a documentary. Honestly, while I had high hopes, I felt somewhat unsatisfied with the content. It seems the swimwear wasn't fully utilized, and especially the shower scene with the breast sandwiching is the only highlight. The acting skills are improving, and the scenes of her breasts shaking are impressive, but it seems the appeal has halved compared to her past works. Nevertheless, the actress's presence is outstanding, and there are indeed some amazing moments included. Overall, I give it a hopeful ☆4, but is it really recommendable to purchase on the release day…?
