The work depicting the mysterious college girl circle 'Iron Lily' focuses on lesbian training through iron restraints. While the hardcore SM elements are toned down, viewers can enjoy the intimacy between women. Many are satisfied with the quality of acting, the contrast between iron and women, and the development of the plot. However, there are also dissenting voices regarding the lack of effective differentiation and the sidelining of specific characters. Nevertheless, the unfolding of a lesbian love triangle among the main characters and the highlights of the training scenes offer much to enjoy, making it a recommended work for iron restraint enthusiasts.
