I have to admit that I read many glowing reviews for Mahoraba: Heartful Days, and I can see why after watching it myself. The story follows the usual format of "boy wants girl" while having to deal with a wodge of meddling, strange and very pecuiliar roomies. The girl, Aoba Kozue, has everything going for her except..... Yes, she suffers from MPD, and everybody around her knows about it, except for boy (Shiratori, Ryushi ). What follows is a romp of enjoyment. The main characters are well developed (and all rather odd in their own way), and the story moves forward without loosingsight of the "boy wants girl" goal.
It is really funny at times, and tragic at the same time because Kozue is really a very likeable and amiable character, and everybody around her does their level best to protect her from falling into one of her alter egos.
I loved the ED ("Boku no SPEED de" by Chihiro Yonekura) and I loved the storybook like titles and the 4-koma strips in some of the episodes. In fact the only real failing as far as I was concerned was the ending, this one was just too good to stop at 26 episodes.
The MPD issue is a difficult one though, but it doesnt detract from the story on its own, and the alter egos are hilarious themselves, providing that extra bit of strangeness that works so well in the series.
Artwork is perfect, fitting into the mood of a particular episode. This is a 2005 series so the artwork does fit into the style from that period. Do not expect slick and shiney though, it would not work here. This is a playful series, at times you would think it is a storybook you are watching, but that just makes it that little bit more unique.
I would say that this was one of those unique finds that very few people every watch, but those who discover the series are very lucky, because this is probably one of the better anime of this genre around.
