Lady Butterfly and, Sekiro/Wolf have encountered each other in the past; she remarks on this by saying, "It has been quite some time son of Owl," before the fight. When consuming her memory, you realize that your foster father employed her to teach you some of the techniques that made you into the shinobi you are today. Her fighting style is extremely unique when compared to other characters and bosses. She seems to fight like the ministry's lone shadows, with her even deflecting with her leg identical to how the lone shadows deflect with their leg. This style could also be confused with the Temple style that the high monks of Senpou Temple use, since they also incorporate their legs into fighting, unlike the Ashina style or the Shinobi style. This isn't to say that she doesn't use the Shinobi style, as she also uses shuriken similar to the Owl. We can assume that her being Wolf's mentor is the reason why he is able to learn 4 different styles of fighting seamlessly. Lore theories should be clearly marked as such. "Butterfly" is a common female name in Japan until the early 20th century. For example, the personal name of Lady No (the wife of Nobunaga Oda) was possibly Kocho ("butterfly") in some accounts. Another famous instance (in fiction) is the opera Madam Butterfly composed by Puccini, where a Japanese girl Chocho ("butterfly") is the protagonist. In East Asia, butterflies are often associated with illusions and dreams that are indistinguishable from reality, as in the story of "The Butterfly Dream" in Zhuangzi, 3rd century BC, China.
