A gag manga, plain and simple fun! Until it isn't! While it seems like the bit would run stale quickly, the art style really compliments the hilarity of the situation. Additionally, I enjoy reading various ways that they try to skirt the boundaries of what's allowed, but also if the consequences of such a seemingly hilarious but ultimately tragic supe rnatural phenomenon. The characterization of the father makes it a big hard to like him, but he redeems himself in his funny reactions. In a way, it is a nightmare scenario. They will never truly be able to enjoy a normal livelihood ever again thanks to theabsurd premise, but it still ends up being a comedic romp.

Give a read if you're not too stingy on laughing about gray humor.

Final notes:
When I first read this, I was in a relationship with a Brazilian girl who had the nicest ass I've ever seen.

And then she cheated on me because I didn't want to learn Portuguese.

The lesson? Learn Portuguese, or bang your girlfriend before she cheats on you for not learning Portuguese.
