Kenji saying that it is the second time he's met Naoto but you would think it should be three (Naoto warning Kenji at the beginning of this loop, when Kenji attacked the other hero in the kingdom, and now this time). Wonder why that is.
The Demon Lord already being defeated... could it be that somehow he was not resurrected when Naoto went back in time? Even if Foderlinz does not exist, you would imagine there should be other demons that could be sent to attack the village and guard the Hero's Sword.
