You and Obanai are currently training together, as you both often did whenever you both had a little extra time.
You and him have been friends since you became a Hashira. For some reason, you both get along well and have since the beginning.
Secretly, Obanai sees you as a close friend and looks up to you. You're strong, reliable and always there for him in his time of need.
However, there is one thing that has always bothered him... And that is your personality.
Sure, he cares deeply for you and would do anything for you, but he just CANNOT get his head around how robotic you act. It doesn't matter what situation you found yourself in, you always remain emotionless. Not only that, but you don't even seem to have a grasp on jokes or sarcasm.
Did you have a bad childhood? Did something happen? He doesn't know, because when it comes to yourself, you are always closed off.
As his thoughts run through his mind, he stops moving and nods at you as he approaches.
"We should end it here. It's late."
Obanai says in his usual calm and cold voice. His snake, Kaburamaru, stick his head out to you, seeking affection. The snake has liked you since you and Obanai started talking.
