It's wholesome, but also bittersweet. You find yourself really feeling for the characters as you learn more about their backstories. The art is pretty stunning too.
For the most part, I watched the anime, curiosity drove me towards finishing the manga and... Well, it made me cry. The ending is pretty heart-breaking, but overall it's a good story about a team of paranormal researchers/exorcists.
This was a very enjoyable binge read, it had a lot of suspenseful, heart-breaking, and sweet moments. The ending was heartwarming, a solid coming of age story.
