Yamazaki Susumu is held in high regard by the high-ranking members of the Shinsengumi, especially Hijikata. He is a shinobi and the type that gathers information night and day. Like a typical ninja, he leaps from roof to roof silently, but during the day he dons kimonos and powders his face, transforming himself into a beautiful lady (known as 'Osei') so as to collect info for the Shinsengumi. Like most ninjas, Susumu has a cold, indifferent attitude to those around him, particularly his peers and people he considers weak (such as Tetsu). Susumu is rarely seen losing his temper but with Tetsu he was the first to do that.
