Originality was covered in part by my review of the storyline, but it shoudl also be mentioned here: While the individual aspects of the plot seem to be very common themes in anime, the way in which there elements are put together and made into a single flowing story , so it's not a knock off of another series, it is it's own identity.

One thing I am glad to notice is minimal use of super deformed mode. While I don't dislike super deformed completly, I find that it used all to often when it isn't even needed for the bit of humor , which dulls it's effectiveness when it should be used. And while there is a lot of comedy involved, the comedy generally isn't placed in such a way as to hurt the flow of the story.
