Honestly this is a great manga but the isekai part of it is so lackluster. There is 0 need for it to be an isekai cause it has little impact on the story whatsoever.. I’d like it if it had more use of his knowledge from earth
Hope they go back to the main story , exposition for the characters is needed but it feels like the main story goes down the drain when we get so sidetracked.
Id rather they advance the plot every so often or interlink things atleast so they have a deeper meaning to the plot.
