Spoiler for Chapter 12:

There hasn't really been an "enemy" as far as this series is concerned. Arin might count but she's forced to work with Amata enough that it isn't really an issue and she might as well just be a tsundere. The older twin might be someone that Arata will have trouble accessing. Maybe.
