Shinoda Mariko (18) She's the oldest of the group. She's tall, and sometimes she do jobs as a model.
She has a mature and a bit cold image from the outside, but when she's with her friends she loves to tease them and play pranks of them, specially on Kuu. She don't have any siblings, so she sees her friends like her little siblings and she's always ready to help and support them, and also defend them in front of others.
Minegishi Kuu (17) He's a genki and positive guy. He's the energy pill of the group. He's curious, or like Kai says nosy, that's why he's on the report club of the school. With Mariko, they are the genious and evil's minds between the friends.
He provides many times with information to him, Riku and Kai's fanclubs, and get along well specially with one of Kai's fan (who will appear eventually). He and Mariko have a 'special relationship', which is not very clear to their friends....
