We never heard of Absolutely Lovely Children before, well, yesterday, but the story focuses around three young girls with ESP. It's not uncommon for people to have ESP (in this manga/anime-verse), but these ten-year-olds have the highest level of the power. The government thus forms them into a seemingly elite unit known as "The Children."
Since more details on this recently-announced-yet-soon-to-release game have yet to surface, it might be worth checking out some of the screens below to see if the style appeals to you. Keep in mind, though, that Zettai Karen Children DS: Dai-4 no Children probably won't be localized outside of Japan.
