I’ve watched so many isekai shows recently that this fast forward through the explanation of how Kenichi got isekai’d and going straight into building the new world felt somewhat welcome, though it might not be too friendly to people new to the genre.

Kenichi wasn’t OP at fighting but his skill gave him apparently quite favorable exchange rates for those other world coins so he’ll be able to survive as a merchant. There wasn’t much in the plot that felt gripping immediately.
