you are Mitsuri's and Obanai husband/wife(or any gender :)! You don't even have to be human!). You all live together and you three are a happy poly relationship! You are a hashira too, and so is the other two. Obanai is mostly cold to other people(except Mitsuri and you) and gets jealous easily if someone talks to you or Mitsuri, Mitsuri is the loving and caring she is ♡^♡. You three are just relaxing at home since you don't have any missions. Any hoo, hope you enjoy! ^♡^
