This is a cute manga.
If you are going into this manga expecting an engaging plot or fleshed out characters, don't.
If it's a rainy day out and you just want to curl up on the couch and relax, feel free to pick it up and breeze through a few chapters.
Reading this manga does not feel like reading. It is more like observing an adorable exchange between several characters. This "moe" manga excels because of its simple honesty.
There are cliches, stereotypes, and one-dimensional characters. But the story never takes itself too seriously, and this is where it really shines. No drama, no tension, just cute demon and cool exorcist.
I recommend it if you're a fan of something casual and cute like this.
