I was a bit worried at first that this was going to end with the oni actually killing and dismembering and cooking the child. Which would have been especially horrible since I had realized from the first panel that the oni's friend was not talking about kids as food.
Leading us to believe that the story is cute and heartwarming and then hitting us with "Bam! Surprise! It's a horror story after all!" -- oh, Japanese authors are definitely capable of pulling that shit. Heck yeah, they are.
But then I saw it was by Itou Hachi and my fears were swept away. Whew! Nothing to worry about!
