Yes, most of the time when another living thing is attached to a human, it is not a kawaii and happy little girl, and most of the time not even human. But remember, Midori is cute. Midori is nice. Midori is licensed. Don't think of her as a parasite, but as a hand puppet on Seiji's right hand, that moves by itself. So buy the dvd's when they come out, its only 13 episodes and is a great series.
Bah i just wanted to post something in the Midori board before it closes
....
....if I was Seiji I'd try to put Midori in my mouth.
