They say when you make a decision that an alternate universe is made that reflects the choice you didn't choose.
Kashina is the main part of this picture as it reflects both alternate universes, if she decided to stay or not.
The left one is the Risa the Fox Sharon, where Risa the Fox and Sharon won an audition to become a CyberDynian 5 member and beat Rocky, but was ultimately beaten by Risa the Fox who turned on her forcing her to go back to the Shanty Town she lived in.
The right one is the Ninja Mouse Sharon, where Kashina decided to stay and both decided to join try out for the CyberDynian 5 after Kashina saw a recruitment poster for them. They both fought Rocky and beaten him working like two graceful swans and ultimately beaten Annie over her trying to one against the other making them both fifth ranked members ending Sharon's life of poverty.
