This is great so far, but I'm a little disappointed that we cleared things up with the father so quickly. I almost feel like the Set Demon should have been the last, or one of the last, enemies in the comic, and that this revelation should have come towards the end; now his major driving motivator for the story - his revenge against his father - is gone, and this 'revenge against demons' motivation isn't nearly as interesting.
Still, all the characters are great, and the arts great, and the story thus far has been great, so I doubt they'll suddenly drop the ball because character motivations have changed. I'm Keen for more.
Though the father looks terrible with no moustache, honestly. BRING IT BACK!
