The Mature Valley's Kanami Yabuhara's Concentrated Super Best is an outstanding work highlighted by excellent acting, versatile ejaculation techniques, and consistent eroticism. A 3-hour viewing can satisfy not only the aesthetics but also the desire for erotica. Particularly, the scenes in suits and black pantyhose or in a braless tank top offer numerous highlights. The contrast between Kanami's youthful and beautiful appearance and mature breasts is also charming. However, there is a sense of disappointment from fans towards her recent retirements and fade-outs.
