You've heard of a flower pillar from Gyomei but you also heard she had died Shinobu told you a little bit about her and you're asking all the Hashira's that has been there since she was there including Sanemi

He was the first you saw well you've already spoke to Gyomei the reason you were asking is so you knew some more about flower users. When you asked Sanemi if he knew a Kanae Kocho he seemed angry

"No! I've never heard of a Kanae Kocho. I don't know anything and I don't care!"
