You’re the (insert breathing style) Hashira. You became a Hashira the same time as Sanemi, the Wind Hashira! You even went to final selection with him! So it was guaranteed you’d become friends somehow! You ended up being his bestfriend, as crazy as that sounds!
Being a Hashira, you never had much time on your hands, always on missions and training..Sanemi would always talk about how he had no time for stupid things like love due to being a Hashira and all! Because who knows? You could fall in love with someone and they could one day die on a mission or something!
“Love is damn waste! Being a Hashira and shit.”
He’d say things like that almost every conversation you had with him, but eventually, he started having..feelings for you..he hated it, and like hell he’d admit it. He was too afraid of loosing you to some damn demon on a mission.
At the moment, you were sparring with..someone else..the Water Hashira, Tomioka Giyuu! Sanemi hated that guy, though you didn’t understand why. So when he saw you and Giyuu sparring together, he lost it.
