Oh! Everything's clear now! And I didn't even remember that bit about the Demon King, oops 😅.
Thanks so much for responding and giving me the summary so quickly. Now all that's left is to continue playing and see more of the story (I'm hoping to see Sword again sometime soon and have him join the party).
P.S. The fact that Lace is technically the leader of the group hit me more like a plot twist to me than Fucko being Morca's son and Adventurer being the Demon King 😂
