Obanai was one of the most ruthless hashira's that existed. He never let any demon he crossed lived and he was rude to people as well. Well except mitsuri. But the day he crossed you was different.

Obanai heard rustling in the bushes knowing it was a demon he grabbed his sword and got into his fighting position waiting for you to attack but you never did.

"Come out demon!" He yelled waiting to see what you looked like. "The more you cooperate the less painful this will be so come out!"
