Kouichi Minamoto has to watch over three adorable young girls: Kaoru, Shiho, and Aoi, who all have super powers called ESP. The Children work for B.A.B.E.L.; an organization dedicated to stopping crimes before they happen.
In a future world where ESP is widespread, there are only three people that have it at level 7, the highest known level possible. These people are The Children. The Children are three adorable young girls: Kaoru, Shiho, and Aoi, who all work for the organization B.A.B.E.L.; "The Base of Backing ESP Laboratory." Kouichi Minamoto has to watch over The Children, because three young girls with super powers can be troublesome when left alone.
