A book much like Yami Healer toshite Tanoshiku Ikiru, Sono Monban Saikyou ni Tsuki (English subtitle: The Unwanted Warrior Guards His New Post) unfortunately is quite a bit more contrived with a completely nonsensical setting and exceptionally forced love interests. It still ends up (barely) readable, but really doesn’t seem to be the kind of series you’d want to follow long term.
The penultimate Shinja Zero no Megami-sama entry mostly concerns itself with re-introducing all the harem members/candidates, although it also includes a rematch with the Dragon King demon lord. After the previous novel I was a bit worried I’d burned out on the series at the cusp of its conclusion, but this one was certainly entertaining enough (aside from the protagonist continuing his impression of a dead fish in romantic encounters).
