After seeing the Fruits Basket anime series and reading the first volume of the manga, I decided to keep reading the manga to see how it compared with the anime series.
In this volume, Tohru starts learning a little more about the Sohma family and their secret. When Tohru's best friends, Hana and Uo come over to the house for a sleepover to get to know the guys Tohru is living with, Tohru and the Sohmas have to make sure that the girls don't learn the secret (that the Sohmas turn into animals from the Chinese zodiac when they're hugged by a member of the opposite sex).
Overall, the anime follows this manga volume... with one exception. In the anime, the three Sohmas change into their animals forms at times their vistors aren't looking, and Tohru has to make sure that her friends don't put two and two together. In the manga, however, the boys never change into their animal forms, and the card game they're playing is extended out. Also, in the anime there is a one-sentence background on Hana, and brief flashback of how Uo met Tohru. However, this information doesn't come out at this point in the manga series; this information is revealed in later volumes.
I really enjoy the Fruits Basket series (both the anime and the manga). If you read the first volume of the manga and enjoy it, I believe that you won't be disappointed by the next volume.
I wrote this review after checking out a copy of this manga volume through the King County Library System.
