Growing up is hard enough for most girls, but for Class 7 espers Kaoru, Shiho and Aoi, who have to do it while also protecting the world as part of B.A.B.E.L., it's even rougher. It's bad enough that they're feared by most of the population just for being what they are, but when they also have to act as police against other older and more experienced espers AND still go to school, they're getting an early education into how unfair the real world can be. And just to make matters worse, now there's an esper vigilante to deal with and a new mysterious organization called P.A.N.D.R.A. on the rise. Can the girls' highly put-upon supervisor and guardian Minamoto keep his charges from losing control in every possible sense? The action continues as three little girls with Class 7 sized growing pains threaten to bring down the house in the second mind-blowing collection of PSYCHIC SQUAD!
