Oh, I forgot my favorite scene this episode.

The other girls teasing Sarasa about having a boyfriend back home in the very typical anime/manga manner, and she bluntly replies, "Yep! He's in Tokyo, but it could be him," which leaves them all speechless for a second, and even then they kinda doubt her. Then it dawns on them all that yes, she's beat them all to having a relationship with a man.
