Honestly this is like a "second" demo. All this is just the introductory part.
The first one played by my friends had little to no exposure and they said the player wouldn't invest with the MC if they didnt know the motives and the basis of the setting, and seeing how far most of you guys went, that seems right.
Right after the end of demo, there will be day passage, you can choose to train or read, or travel around, and there's gonna be battle passages.
Not much info dump then, unless you ask for it (by reading books or asking people).
