The sixth Shinja Zero no Megami-sama book continues on from the previous in much the same way. The protagonist gains another, albeit limited, ability (tied to his weapon) while additional harem candidates are introduced. Far better pacing however.
Kasei Madoushi’s fourth novel also continues directly from where its predecessor left off. Difference here being that it’s concluding an arc rather than starting one. Unlike the previous novels, this one focuses more on action/drama for most of its pagetime with only the last third or so featuring a notable amount of ‘housekeeping’. Only noteworthy issue is some odd recap placement: For some reason a character who you’ve just spent half the book with gets re-introduced as if you’ve never seen her before.
