Yuri is a delicate lily flower, while "yaoi" is sometimes written with the kanji 矢追, literally meaning "arrow-chaser." While chasing arrows is not directly linked to combat prowess, this strongly implies the entity has enough martial aptitude to defeat an ordinary flower.
Yaoi is also the surname of Jun'ichi Yaoi, who is basically the Japanese version of the Ancient Aliens guy. He's 87 years old, but he can probably still stomp out a lily flower.
