Don't know the name of this urban fantasy manga about Yokai

[spurgleburgle]

I don't think I ever read this series on mangadex, and it wasn't too big of a series, so it may be hard to identify, but I might as well give it a try. The story takes place in a city inhabited by mythological creatures, mostly Yokai. The protagonist is a human (I think) woman, but she wields a talking gun that belonged to her late lover and has inherited his personality, and her assistant is a Kappa. She's a detective or something similar. The series had plenty of action, and switched between darker and lighter tones. Most chapters were standalone. I remember a few chapters, including:
[ul]a chapter involving a race between Yokai,[/ul]
[ul]a chapter that introduces a dishelved drunk who turns out to be Santa, and the MC has to help him out somehow,[/ul]
[ul]an arc where

Spoiler

the Kappa assistant is revealed to have been part of a scheme working with fellow Kappas, though he regrets his betrayal and returns to her side at the climax,

and[/ul]
[ul]a chapter where the MC is hired by the Egyptian god Ra to eliminate what turns out to be a baby, and is in fact the grandchild of Ra, and child of Bastet, Ra's daughter, that she had with...a werewolf or some kind of mythological dogman. The MC refuses to kill the baby and gives it to an orphanage at the end.[/ul]

If anybody can identify this series, that'd make my day.

I never read the manga too far but what you wrote reminded me of "Area 51" (https://mangadex.org/title/14772). Judging by the manga description it seems to fit perfectly.
Hope i could help

@Nimeri Oh wow, that was exactly it! Thanks for finding it! I should have looked harder, but I didn't recognize it from the cover.
