Enthralling from start to finish.
Impressions:
Let's see… They ate, they took a bath, they worked at a cafe, they did some paperwork, and they took another bath. Talk about a roller coaster ride from start to finish. Specifically one of those caterpillar ones for 5 year olds that look like the stuff of nightmares, yet only go in a 30 foot loop at sub-walking speed. I guess the main point was to introduce the no-fun-allowed sister character through the time-honored tradition of "here's some random character who's going to do jack squat." I guess be a sounding board so everyone else can explain the main character's traits again? But the secondary and more focused-upon 'point' was to fill up some time with fanservice because having a plot is haaaard. And manservice. Although since one side of that coin consisted of about three stills of sparkly naked men, and the other side consisted of Kuon splashing around, breasts flailing wildly, and all the girls rubbing themselves on each other, it's not exactly hard to tell what the target is.
