Reply to review: I was just kinda unsure about my overall idea, so I just gave a short little pilot to see if it was an idea that could pick up with the readers. Also, the reason I only included the main four girls is because I don't really know the characters as well as them. Who knows, maybe in future I'll go on to include Yutaka or someone, but for now, I'm only going to stick to the four I know best in Lucky Star. And don't worry, the way things are going, it looks like there definitely will be a next time
And on a final note, of course Kagami has something to hide, if she's wearing a diaper at school in front of her three best friends :P
