Tsukumodo Antique Shop's first few volumes was a novel I read alongside Utsuro no Hako to Zero no Maria, back when I still new to light novels.
So, imagine this scenario: there's someone new to light novels, and those two novels were the very first ones he read. At the time (and to this point), he likes one as much as the other. Years later, I still have difficulty finding novels that can rival the writings of those novels. From the top of my head, I can only name probably novels like Biblia Koshodou or works by Sugaru Miaki that can rival them.
Now of course, as a random anonymous person, my opinions hold little to no importance. But I do hope my point comes across, point beingTsukumodo Kottouten is an excellent novel.
I would also very like "Usotsuki" to be published, foremost because the character's dialogues are intersting and the protagonist's lies, to the reader and other characters, are, at least for me, both entertaining and unique.
