well, the story tries to establish hurdles that feel somewhat natural, even though the whole isekai part in itself is the direct opposite. he had to secure his place in the clan with Ai Fa, he had to secure his place in the village, he had to establish a shop without any credentials, all events which feel quite natural, so i guess the next arc will be similar in tone. maybe asuta will open a restaurant, turning this into a weird kind of izakaya story, or the village will face a manmade/natural disaster so he needs to adapt to it.
at the moment though, yeah, there's not much going, aside from introducing new characters, but i'd still expect a few arcs here.
