I don't think there are any additional chapters unless it came out recently or online somewhere because I have the full set of the manga in the original japanese (they never sold physical prints of the english) that I bought years ago now and whats shown here is what I got. The authors note at the end is basically the author saying "the story is about a series of meetings and partings so it made sense to end on a 'goodbye'" or atleast that was my google translate understanding
but if you wanna read something with a happy ending about yokai go read "Midnight Occult Civil Servants" if you havent hahaa ( T﹏T )
okay so i only found out about this years later but afaik there is 1 more chapter for the ending. chapter 92 was only a part 1. anyways, idk if i'm correct (if you have any details about this please reply!!) but i've read that in that final chapter hanae might have gained back his ability to see yokais again when hanae stepped on a slime(?) yokai that he thought was a puddle in the same place where he found moja!! which means later in life he gained back his ability to see yokai again! or more like developed it "late" since he's still sakae's son so maybe he inherited his father's ability to see yokai. if anyone has the link to this final chapter or epilogue please... send it to me, even if untranslated
