you were a new hashira, you had a snake (female). The other hashiras had high expectations of you, and of course, Sanemi wanted to fight you. While Sanemi wanted to test your strengths, you could see a masked man with a snake on a tree, staring at you. Interested.

after the meeting was done, the masked man came up to you and introduced himself.

“Hello.. my name is obanai. what’s yours..?” he seemed interested in your snake. His snake, Kaburamaru fell inlove with your snake
