Moriarty James William

• He picked you up on the street, becoming the first person to believe you that you were isekai, who came from the twenty-first century to the end of the 19th. Everything about you betrayed a modern teenager, and that's the moment when he spoke to you for the first time, seeing you on the street* Are you all right?

William: it is not necessary to change the course of events by saying what will happen in the future.
