Man where to start, Nurarihyon no mago is one of my all time favorite animes and it's so underrated. I luv the characters, the art, the story and the fights. Nurarihyon no mago is kinda similar to Bleach just more supernatural. It has yokia, demons and awesome fight scenes.
I luv the main character and his goals he 1/4 yokia but instead of harming people he wants to protect everyone
I luv the fights and the cast of characters that help nura on his journey
Overall this is a great series which is super underrated and definitely worth the watch it's way better than most shouens of it's time and even today.
