Three of the most powerful espers in the world, Kaoru, a brash psychokinetic who can move objects with her mind; Shiho, a sarcastic and dark‑natured psychometric who can extract thoughts from people and read the histories of inanimate objects as if they were books; and Aoi, the most composed and rational of the trio, who can teleport herself and others at will, are cute and adorable. What do you do with such potential psychic monsters? They are sent to B.A.B.E.L., the Base of Backing ESP Laboratory, where the hope is that “The Children” and others like them can help counter the escalating wave of psychic evolution. It seems like a win‑win solution… unless you’re Koichi Minamoto, an overworked young man tasked with field‑commanding a team of three pre‑teen girls.
