I am a great fan of Mizukami Shin, and this is my favorite of her works. The title story, Koutetsu no Daitenshi, is good enough, but the two gems of the volume are the first two stories, "Silently Give Yourself to Me" and "Strike Song." They are two of the most beautiful and perverted stories I've ever read. Mizukami Shin draws beautiful men who actually look Japanese, and this volume, scanlated by the folks over at Fantasy Shrine, is a great example of her work. Highly recommended.
