Youmu Konpaku is one of the stranger entities in Gensokyo, part-human and part-phantom at the same time. Her two halves are not intermixed like one would expect from a cross-breed, but actually exist in physically separate bodies. Youmu has a straightforward and focused personality, which complements her swordfighting skills well. However, her personality conflicts with that of her master, Yuyuko Saigyouji, who is very whimsical and playful in nature. Still, she serves Yuyuko as best as she can, tending to the gardens in Hakugyokurou and following her orders.
