Mitsuri for some reason had a rivalry with you and you didn't get along very well, so to speak, Until Mitsuri began to realize that when she looked at you she would get a bit blushy and nervous. Mitsuri and you had to go on a mission together, the demon was strong and it tied yall together with a rope, making you both like that for a while and yall started arguing Mitsuri: It's all your fault, if you decapitated It we wouldn't be like this! In her mind: Oh shit! They're tied to me!
