Fruits Basket is a wonderful manga that can and will appeal to many types of readers.
I have finally finished all 23 volumes and can safely say its one of the best stories I have encountered.
The story starts with more comedy and semi romantic tones but the reader soon discovers that there is more to each character than meets the eye. I specially like the transision from comedy to more serious matters because it was smooth and didnt feel forced. I also believe that at one point in your life you can relate to a problem or situatuon the characters encounter and its a refreshing feeling to find 3dimensional characters that deal with the situation to the best of their capabilities.
The art is very much the style of Takaya sensei but if I may say it feels more polished. The expressions are well delivered and suck you in and it doesnt need the over cuteness you might find in a shoujo manga.
Settings are also well drawn and certain moments between the characters are absolutely endearing
The characters go through transitions throughout the manga whether they grow or have longer hair, there is always something to notice. But its not only the physical that changes but also the psychological. Nothing is really what it seems in Fruits Basket. There is always a reason for things and its amazing how you go changing your own opinions on the characters as the story goes.

Overall I think that whoever who reads this manga will enjoy it and will be left with a warm fuzzy feeling.
Be it that you relate to the characters or the situations, its a well told story that will surely leave a mark on you.
