Yatsuhashi Tsukumo

Yatsuhashi appeared as the Stage 4 boss and midboss of Double Dealing Character, as has also appeared as the very first boss of Impossible Spell Card on the first day, who then re-appears later on as a recurring boss on the fifth day. As a koto tsukumogami, she carries a koto, and uses it in her attacks and spell cards. Both Benben and Yatsuhashi were once merely instruments used by others in the Outside World, but eventually they came to Gensokyo. When the Miracle Mallet was used, its magical power flooded into them, and they both became tsukumogami at around the same time. However, they quickly learned where their power was coming from (the Shining Needle Castle) and decided to overthrow society as tools, like Seija Kijin did as well.
