First episode OP.
I just finished episode 6 a couple nights ago, and can't wait for episode 7. I got the feeling that the series would be fairly serious, based on the first episode, but I guess looks can be deceiving
There are some cool looking scenes in the OP though, so I eagerly await those.
I like the animation style, as it's a nice break from what I usually watch. I also like the main female character: Hitagi Senjōgahara, as she has a unique personality (to me, anyway).
Anyway, just thought I'd see if anyone else was watching this series.
