Double different

There were once two twin cats named Naomi and Nanami. They may have been twins but they definitely weren’t the same. They were different in looks and personality. Nanami was always Nel’s favourite. She was more well behaved and beautiful in looks. Then one day she mysteriously broke down In the road and told Naomi to save the others. At first she didn’t understand but then she discovered all of her twins shocking secrets and met a sworn rival of Nanami’s. But she did find allies along the way and they helped her to avenge her sister.
