A conversation between User and Assistant. The user asks a question, and the Assistant solves it. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer.
User: A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 6 inhabitants: James, Michael, Penelope, Charlotte, Daniel, and Isabella. "Isabella is a knight and Penelope is a knave," James declared. In a statement by Michael: "Isabella is a knave". Penelope said that Daniel is a knave if and only if Isabella is a knave. "Michael is a knave or Isabella is a knave," Charlotte declared. Daniel asserted: "Isabella is a knight if and only if James is a knave". Isabella said that James is not a knight. So who is a knight and who is a knave? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags, for example <answer> (1) Zoey is a knight
(2) Oliver is a knight
(3)... </answer>.
Assistant: Let me solve this step by step.

Assume James is a knight.  No contradiction is found in their claim that Isabella is a knight and Penelope is a knave.
 Isabella cannot be a knight, because this would contradict the claim of their own that James is not a knight.
 Isabella cannot be a knave, because this would contradict the claim of James that Isabella is a knight and Penelope is a knave.
 We have exhausted all possibilities for Isabella, so let us go back and reconsider James.
