Next on the list is animation; its pretty dang good. The characters models are defined well enough but one thing I have noticed that really sticks out are the facial expressions. The one-on-one scenes between Riki and Rin are especially apparent because the expressions Rin gives draws out her honest feelings. It sounds weird and I just may be giving the show too much credit but when I first watched the second episode, the scene where Rin is outside with the cats was a really well done scene animation wise.
Sound so far is what you expect for a modern day anime, great voice actors that have been recorded fairly well. The background music has done its job because while I don't notice it over what is going on, it doesn't steal my attention away from the plot. It's not amazing but it does it's job well.
Other than what I have already said, this anime looks like it has potential to be my sleeper pick this season. I cannot comment on the plot because well..its only been two episodes but I hope it flourishes into something unique (which seems to be very hard for modern day anime and manga to accomplish).
