I just started reading it and im really enjoying the story and art style. Idk if you’ve fixed it in later updates but my only critique is that some of the text is a little small to read comfortably on mobile.
Otherwise the only things i can think of that could be causing a drop in views is some readers dont have time to read updates immediately and let them build up to to binge later. Also, related to that, since theres a lot of updates most new readers will take a while to get up to date hence most the views being on the older chapters and the newest chapters only getting a few views per update.
Also changing the main genre from fantasy to mystery or horror would probably help increase readership as updates only show up in the main category and most the fantasy comics are more angels, demons, werewolves, isekai, high fantasy etc than real-world supernatural mysteries (and presumably the former is what most readers within the category are looking for).
Also fantasy is one of the most saturated genres so you’ll likely have more chances of being seen on one of the other categories aswell
