Finally! I have been waiting for this for a long time!!! They have conversation at the store as they now know each other. Mitzuki no longer completely covers herself anymore! Maybe she does not need to take off her piercing while at school.
Hard doubt on the not removing piercing for school considering her school most likely has a dress code that doesn't allow it. There's a difference between hiding who you are and taking out a piercing so you don't have to deal with being yelled at for it at school.
While this is true most of the time, I don't think it's the case with this school's rules, since Narita and Aya both go there daily with piercing, nail polish and makeup, and nobody ever say anything about it.
It's still Mitsuki who doesn't want to stand up at school, the only place where she can be herself is her Uncle's CD shop, for now.
