Books like Nightmare Inspector: Yumekui Kenbun, Vol. 1: Lost Things

I've only read volumes 1, 2, and 4 of this series, as that was all my library had; Goodreads listing suggests there may be 9. I liked the concept and the setup. A mysterious individual billed as a nightmare eater has set up shop in small tea house, with each chapter or so centering on a different client coming in with a different dream problem. From the background technology and costumes, time period seems to be late 1920s or early 1930s, post the Kanto earthquake by one remark.The art seemed a little dark and muddled, but that may have been in part from reading it on a small paperback page, after being spoiled by the larger and brighter tablet screen for manga.I think this is too small a sample to judge characterizations. The regulars had some promise as far as I got, not yet fulfilled. The dream-eating possessor-spirit of the unhappily deathless baku was the most intriguing so far.Ta, L.
