The Hero’s Party’s Main Fighter Is Actually the Demon King

A brave man is no stronger than an ordinary miner. Absolutely. Conditions are so difficult, do miners have protein to eat? Moreover, the demon king's world has magic power, and there is magic power to bless it, and there is magic power to passively strengthen the physical body. I cannot accept that the strength of a brave man is no better than that of a poor miner. You, the brave man, are so exhausted that your entire world view has collapsed.
