A rather interesting episode. Very character and character interaction oriented. Nothing much about the academy itself is learned. Or about the actual job of the teacher Hayato. Maybe this was an episode to give some depth to a few characters so that the audience would later better remember them.

The next episode preview showed some intriguing things... I always have hard time remembering this show is scifi as well, not just ninja fantasy.

Partly in accordance with Mog's comment I have to say the voice actress of Himawari does sound quite interesting and quite unlike most of the voice actresses I have before heard. There is something unique about her voice and performance. I'm not saying it would be exceptionally good or anything like that. It just feels different.
