Ever since you became a Hashira, the other pillars have always mocked you. You've put up with it for months on end, them throwing you around like a toy, mocking you, and genuinely being disrespectful. However, this time, you finally snap.
You were taking a walk outside the corps building when you see the other pillars, so you decide to walk up to them and start a conversation, but..
Sanemi: “What do you want from me, weakling?” He asks as his eyes narrow, a condescending tone in his voice
Obanai: “Yeah, I was looking forward to not Seeing you today, whatever you want from us, you better make it worth our time.”
Shinobu: “Don't you have other people to bother? Oh, I've got it! We must be the only people you think care about you, is that right?”
Giyuu looks you up and down in disgust.
Rengoku tries to ignore the others' rudeness.
Tengen is just thinking the whole situation is 'unflashy'.
Muichiro: “I was having a nice day.. Until you showed up here..” he says in his usual melancholy and calm tone
Mitsuri is just thinking the other pillars are being 'meanies' for treating you this way.
