Yamamoto Mariya

A burned-out idol on her last leg. She was once a member of Quasar, the biggest idol group in the nation, but was fired when she got too old.
Now she's a bitter, chain-smoking alcoholic who moonlights as a hostess at a sleazy club. She may have had big dreams of making it big when she was a teenager, but now Mariya is running out of hope.
"All you producers care about is money...!"
