Story: A fairly straight forward romance between a girl and her best-friend's brother Kyousuke, whom she's in love with. The romance is a godsend after that horrible anime ending. But this manga as a standalone story is not worth reading. Since you need to know these character's before even starting to read it. And the transition from the Prequel Oreimo to this sequel was a bit awkward.
Art: The art is absolutely outstanding. The characters look different from most manga I've seen, but it's really cute and there's no complains about it, considering it's a romantic comedy. (Mayo Chiki is a lot cuter though ^_^)
Characters: Considering the adorable Kuroneko is the heroine, instead of the tsundere little sister, the characters are much more enjoyable in this story. So there's really no complaints. Kyousuke is mature, yet not too much. The friends are all really likable and gives depth to the story.
Overall, I like Kuroneko and Kyousuke, so it was quite relaxing to see their romance develop and turn into something serious. Some might dislike the lack of little sister incest (lol), but the title is self explanatory. This is a different story than the anime. And it's better.
+ Likable Heroine
+ Actual Romance (not just a kiss in the last chapter)
-+ Different from the anime, no little sister heroine
