...I'm kind of torn. Up until the ritual started I was stunned by how awesome it was, and pretty much fell in love with Hitagi. Then we learn of her past, ok, kinda predictable but still not bad. And then comes the end, her story is resolved, and Hitagi acts nice. Damn, I hope she gets back to her usual self by the next episode, or rather, I hope she'll actually be in the next episode. Introducing that awesome character for two episodes only would be the biggest waste imaginable.
On a side note, I hope Shaft's next project will be porn.
