Gritty shifter tale that addresses class hierarchy and the rise of corporations in the power structure. Excellent worldbuilding, the only thing missing was the sound of pachinko parlors ringing up through Shinjuku. Sensitive treatment of a m-m D/s relationship. Only glitch for me was some of the dialogue struck me as odd, overly verbose or complete sentences when fragments would stand in better. Definitely interested in a follow-up.
