I just found out about and watched Zettai Karen Children very recently, and I just loved it. It has to do with espers, so there's definitely a fantasy feeling, and there's also a good amount of humor while still maintaining the driving plot. The characters are also very interesting. I think they could have developed a lot of the characters a little more, but I'm also convinced there will be another season at some point, so maybe they'll continue character development then.
So who's seen this series? What did you think?
