Of course the author doesn't give a name. When Rudeus future self came back in time and introduced himself to his past self, the author simply put a single line. If Rudeus name is not given that time, it will never be given.

My theory is because the author had planned that Rudeus will never tell anyone about his past life, so a name was never needed from the start. Of course, that's only my theory.
