O . o? At no point did they identify the variety of grapes used to make the wine. They were just described as grapes grown in the dunes by the sea. Guess we should also add on a fantasy world as well while we're at it.…this author knows that sea grapes aren't actually grapes, right?
Authors can male isekai MCs that are only good at one thing and not diversify its interpretation, but without good writing that can quickly become one-dimensional and shallow. That’s why most just broaden the interpretation, like that one guy who shoveled so hard he can reinterpret the act of digging in ways like “I just dug the air” or “this laser is just a way to dig”It really must be a difficult thing to try and think you have no way of helping an isekai protagonist; because by nature their abilities skew beyond any rationality into being a Jack Master Of All Trades...
Thank you
Edit: going back to the conversation when they first met
could Kou be the reincarnation of the Greed Dragon?
Except for the first one, the calamities so far have been named one of the seven deadly sins. I suspect the first one, the black dragon, may have been wrath, but the other ones we know of for sure are gluttony, greed, and pride(arrogance). if the story follows that theme we will encounter envy, lust and sloth later on in some way.
Since he recognized both greed and his sister the same way, he likely is a different dragon than greed. I would say it's more likely he could be sloth based on how when he first met her he could not think of a hobby and did not have a job.
Fus Ro Dah!!!so, MC's the son of the dragon?
