Axe at chapter 23. I believe there are 2 reasons why it failed, 1 is due to teh MC having the dumbest name ever. SANTA?????? That's freaking ******, out of all the names, why that. 2nd, there is literally no story or progression whatsoever. The female vampire herself is a sexual deviant who gets off from the weirdo Santa doing it with other girls. Plus it doesn't help the cast is tied between priests and vampires which adds more confusion. 2/5 Manga, art with body proportions are good, sadly that's all it is. There is literally nothing worth staying for the long running story since itdoes not exist.
