Who is mew berry from Tokyo Mew Mew?

Mew Berry from Tokyo Mew Mew is an additional mew Mia Ikumi and Reiko Yoshida added in the manga sequel, "Tokyo Mew Mew A La Mode", I recommend you read it. She is infused with an Andes mountain cat and the Amami black rabbit, also being the new leader of the Mews since Ichigo left with Aoyoma-kun to Study Abroad.
