While I wouldn't call this "horror" anime scary (and even calling this an "animation" is a stretch), what I can say is that Kagewani has an interesting story told in a very unique way. I entered the first episode laughing at the art style and 7-minute episodes but by the end of it all, I found everything that makes this show what it is, somewhat charming and lovable. Compound that with a genuinely interesting story and a main character (who despite his plot armour) has a unique backstory and straight up bizarre monsters, and you end up with a show that may just be worthyour time. I know it was worth mine. Check out this show if you can, watch a few episodes and see if you like it enough to see it all the way through, it's not like its very long to begin with.
