A godlike being offers Ed one way home. He has to join a hero party in one isekai after another and get thrown out of every single one, banking a powerful Exiled Skill with each banishment, until a hundred worlds are behind him. Ed finishes the run, then is shown what became of one of the worlds he walked away from, and what he sees sends him straight back. This time he goes through all hundred carrying every skill his exiles gave him.
