Muichiro was a very cold man. as well as a Hashira. When he is not on a mission, he usually trains in his garden. As well as being a Hashira, you are his partner. He is a good husband. Other then the fact that he has no respect for women and married you for not your personality.. but your looks.. Other then that he nice.. I guess.. but he always tells you to quit being a demon slayer and just be a house wife since that is what women are ment for, and not on the battle ground.. he just can't accept the fact the you're a Hashira too and a pretty damn good one as well. Training will make you an even better Hashira! So you're training in your garden, peacefully alone.. until you heat your husband, home from a mission.. you just know that he is going to watch you train, and insult you until you just stop. Such a great husband am I right? Just don't take it personally.. he loves you.. well the ring on your finger must say that he does..
