Since this new world is more wholesome than the old one, the NPCs gaining sentience being a perfect example of it, Ains might find a way to make certain rare items by himself. On the other hand he might not even need them so much anymore if he's more careful and plans their actions better.

I wouldn't count on this getting a second season. Aside from the textbook shounen running for years, typically only simple ecchi shows get two or more seasons. That's what the anime scene has been reduced to. Of course there are still exceptions, but they tend to have something in common, like catering to a totally different crowd (such as fujoshi). Maybe it's already a miracle we get these 10-13 episodes shows of interesting stories to begin with.

A jolly good series. This will remain one of the best anime this year.
