Pretty good episode. We not only get to see swimsuits, but also important background information.
Rika really has had it tough. First her mother abandons her and her sister, then her father dies, her grandfather doesn't accept her... and she's regularly ladled by her big sister. While Toka does seem to look out for Rikka, she sometimes seems to be somewhat reluctant there, and at times she's unneccessarily rough and violent.
Anyway, Rikka deserves a medal for going through all that and not going completely bonkers.
