Well if there's one thing to point out, its that each chapter is actually like 36 pages, so I'm sure there's a lot more space to really get into the characters here on display.
Frankly, I don't think that helps, because that means every single page has to push the narrative forward, meaning there's no breathing space to undercut the buildup of tension inherent in a constantly-driven plot. There's just too much work from where I'm sitting to get Arata to the point where I wager he would be okay with his apparent-new lot in life.
Like, he's not even starting from zero; he
was at zero the moment Nana appeared in front of him, and then 4 entire chapters were spent with the Jinri and now the non-Jinri Tanuki actively antagonizing and abusing him, ignoring any attempt on his part to make sense of any of this or his requests & demands to enlighten him.
Now he's gone from depressed over his exam failing, to confused about the revelation of magical animal people—and that was his "zero" point. If he'd been actually helped in a constructive way, I could see eighteen 30-something page chapters manage a storyline. But we're now almost a quarter way through and instead his character progression has been going
backward as the Jinri spent this whole time literally kicking him around and keeping him in the dark, despite him repeatedly stating what it was he needed to be at all okay with any of this happening to him.
I'm not convinced that 14 chapters are enough to get him back to baseline and
then to a point where he can just accept his new lot in life, unless we also do timeskips covering weeks to months of in-universe time, and that's kinda sloppy writing in and of itself.
Maybe I'll be wrong. But thus far, I find none of the cast particularly likeable or agreeable with what I would deem a reasonable amount of time to start shifting their portrayal toward a positive light, and the point from which Arata begins his journey toward accepting his new life has been going backward from the starting line and out into the parking lot where he's being repeatedly run over.
