This particular episode felt a bit rushed, in a lot of different ways. First off, whereas in the manga the appearance of different pact forms was the result of a gradual growth in power and control, in the anime it appears to be entirely random (so far, anyway). Secondly, it feels like the show is jumping into the story without taking the time to develop the characters. It feels a bit like watching Tenchi Universe having already seen the OVA: sure, I already know the characters, but watching their development was what was good about the OVA. And a lot more went into Honya-chan's pact in the manga than in this anime version. It seems like the folks making the anime just want to jump into the "magical girl" aspect straightaway.
Finally, the episode itself seemed rushed, with events proceeding with little time taken to develop said events. Still, you notice I gave it a 4. Still quite enjoyable.
