This episode was a good highlight back to episode 2’s focus on Mizuki. As she has been the big sister of the group, but unlike the others which are pushing forward. We have her being comfortable being an assistant. Though the concern of her just being an assistant and thinking she is just replacable makes sense.
It’s great she had her big sister with her because everyone needs someone they can lean on. Her point is right in the grand scheme of things everyone is replacable. Of course it depends on the context of the person. For Futami we know how much Mizuki does for her. She was Futami’s first assistant and she wouldn’t have the same success without her. Mizuki is irreplcable in the eyes of Futami.
