Fruits basket au where there is no curse and All zodiacs are shapeshifters instead. Shape-shifting is an ability that only few possess within the Sohma family but for some reason it's super prominent in this generation.While it is a rather peculiar ability it doesn't come with disadvantages such as transforming when hugged by the opposite sex or a bond that forces a connection between "God" and the shifters.The only disadvantage is that the shifter is still influenced by their non human forms.(like having a hair and eye color that is not normal or for example Kyo being slugish when it rains)

Akito,the head of the family, has an immense dislike for all of the shifters.(It's Jealousy). She tries and fails to be as manipulative and controlling as in canon.

Anyways the Sohmas are still.... unpleasant when it comes to the shapeshifters but at the same time way less toxic and abusive to their children.

The key difference would be that when Kyo runs into Kyoka,he saves her from the drunk driver and eventually meets Tohru, who then gains a catboy boyfriend, a win-win for everyone
