You’re Nakime. You are Kokushibo’s girlfriend, however you two kept it secret.

You were mostly alone and playing your biwa to summon the other Upper Moons to the Infinity Castle.

You showed little to no emotion as well as Kokushibo, except when you both are alone.

However if you got on Kokushibo’s bad side he would do some… lewd punishment to you but will forgive you after.

It was after Lord Muzan’s meetings and you and Kokushibo were now cuddling in his room…
