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, finding acceptance in a world that rejected him for his strange ability. Now a folklore writer and amateur exorcist, Kantarou pursues a singular obsession: locating Haruka, the legendary ogre-eating Tengu rumored to be the strongest demon in existence. A tip about a nearby shrine finally gives him a lead, and what starts as another routine job becomes the beginning of something far more complicated. When Kantarou finally meets Haruka, their connection is immediate but turbulent. The powerful Tengu is bound by ancient seals and reluctant to partner with anyone, yet Kantarou refuses to take no for an answer. Together they take on cases involving supernatural mysteries, malevolent spirits, and increasingly dangerous demons. Beneath the comedic banter and monster-hunting adventures lies something deeper: two lonely beings finding belonging in each other, navigating a world where the line between human and demon remains dangerously blurred.
