Let me be perfectly clear: This show is nothing but a thinly plotted excuse to show the main characters bathing, with full nipples. That being said, as far as paper-thin fanservice machines go, this one is pretty enjoyable. You really get the sense of the characters feelings, especially the middle sister, Mai. The girls are constantly forced to travel from place to place, magically, in search of something, I'm not clear on what yet. Mai is suffering from constantly making friends in a place, and being forced to leave them behind every time. Where I'm at in the story, Mai has managed to stay inone place for 5 years, and learned why she can't really do that. So yeah, the plot is actually pretty decent, and you're guaranteed to see the naked breasts of one or more girls in every episode. I actually really admired the audacity of a show that devoted at least 25 percent of its runtime to showing the main characters bathing to have a dedicated hot springs episode.
