There seems to be a misunderstanding, as Ringo and Berry are not characters who become Mew Mews. Mew Mew characters typically gain their powers through a special genetic infusion or environmental exposure. Ringo and Berry might belong to a different story or franchise.
Ryou Shirogane is from the anime series "Tokyo Mew Mew" .
the very first chapter, when all the mew mews show up, just before they get transformed.
Ichigo has two best friends, Moe and Miwa (from her school), but all the Mew Mews become friends eventually.
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. ---Serenity Robb-- Hope I helped! ;)
