Kantarou sees demons where everyone else sees monsters, so he befriends them instead of killing them, and the show actually means it, treating that choice as radical rather than cute. The chemistry between him and Haruka builds like a slow burn, each case peeling back why a kid who was only ever accepted by spirits would cling to a demon stronger than loneliness itself. Twenty-five episodes is too short to tell this story properly, but what's here carries the weight of Japanese folklore done right, where the real danger isn't the supernatural, it's being the only person in the room who speaks its language.

Kantarou has spent his entire life seeing what others cannot: demons that walk invisible to normal people. Rather than fear them, he befriended these creatures, even as people without his gift shunned and bullied him. Now a folklore writer and demon-buster, Kantarou pursues a singular goal: finding the ogre-eating Tengu, said to be the strongest demon of all, whom he long ago decided to name Haruka. During one job he hears of a nearby shrine where the Tengu is supposedly sealed away. When he finally finds the demon, giving him the name Haruka binds the Tengu to serve him. The series mixes comedy, drama, fantasy and mystery.
