Yuuichirou has always been able to see demons, because he is from a family that descends from a very famous exorcist named Abe no Seimei. His faith in the great Seimei slowly decreases, and he has issues with his father. A visit from Seimei himself turn everything around.
The actual plot felt somewhat hidden. It was a little messy, but not all that bad.
A little different from the usual, the art complemented the manga very nicely. It suited the characters, making the demons look bad and the good guys look good.
Not bad, not good either. There isn't much to say about them. They
felt very one dimensional.
It was an ok read. Wouldn't particularly recommend it, though.
If the plot interests you, you can give it a try, but don't expect the story to deliver more than the premise gives you.
