After Asuka II saw the photo, he remembered that the Holy Girl also had a little squirrel, so he even suspected that Meme was the Holy Girl!In order to eliminate Asuka II's suspicion, Mami agreed to Sado's date and brought a little needle mouse pretending to be a doll to attend; at the same time, Mami had to complete the task of stealing the music box.Can the little needle mouse's acting skills deceive Asuka II and Sado?Can the holy girl complete her mission this time?
