The second Ore dake Level ga Agaru Sekai book is much like the first. It just sort of breezes along doing its own thing not really bothering with any sort of exposition.
Mushoku Tensei‘s twenty-third installment on the other hand waffles about quite a bit. Not much really happens in it beyond a meeting with the mercenaries from the protagonist’s days of impotence and the antagonist acquiring a final ally toward the end.
Looks like there will be one more book of setup and then the twenty-fifth will presumably focus on the showdown with the Man-God’s agents. With only one book left after that… I’m left somewhat concerned over how the series will end.
