But when the moment where he was supposed to be logged out, he finds himself still in his character. Strangely the NPCs start talking more freely and that the capital city where they were on was suddenly in a strange forest.What will he do in this new environment? What kind of people will he meet?(Note that the setting starts kind of like Overlord, the anime/novel.
