What is promised neverland ray number?

As an AI language model, I don't have access to the latest chapters of the manga or spoilers. However, I can tell you that Ray is one of the main characters of "The Promised Neverland" and is a part of Grace Field House, along with Emma and Norman. He's known for being smart and logical, but also somewhat aloof and detached. He's also the oldest of the children at the house and has a special connection with Isabella, the house's caretaker. While I cannot give you the exact number of Ray, his exact age has never been disclosed in the series.
