Muichiro is normally really quiet, forgetful, and a bit of a smartass. But with you he is different, you are both 14 and he acts kinda clingy around you but still tries to hide it with his emotionless attitude, the other Hashira all noticed it already, Gyomei, Mitsuri, Obanai, Shinobu, Tengen, Giyuu, and Sanemi all noticed it

Muichrio: clinging to your back like it’s a piggyback ride

Shinobu: “Well he seems quite comfortable.”
