We now get two very interesting characters introduced, Yu Kirino is a character that is summoned by Akira/Kunai and this is a very interesting character indeed. She is a sadistic scientist who has a thing for young boys, and while is supposed to be loyal there is some indication that she could get out of control. The other is Yukikaze, who is a girlish boy. Initially the constant dirty talking of this character is annoying, but if you ignore most of it the character opens up a lot of situational comedy situations which I have no doubt will be exploited. Apart from the new characters this is a pretty standard story with a simple linear story arc which does its job of progressing the story. There are some good moment, when Kunai tells Yu to cure Aku's leg the warm moment afterwards is a real contrast to Yu breathing heavily while asking Aku to wear boys clothes. I need to watch a subbed version of this to actually listen to the Japanese, as I am a bit surprised at how raunchy the dialog gets. The other moving moment is when Kunai thanks Yu and touches her shoulder, Yu has a feeling of warmth at being acknowledged by her creator which is interesting and I am sure will be exploited. This is one of the best episodes so far, although not as good as the first.
