In the future, people with ESP are becoming more widespread and with it, the necessity of constructively utilizing their unique capabilities. Unfortunately, there are also espers that abuse their powers and wield them to destructive ends. The Japanese government’s solution of choice to both challenges is the establishment of the Base of Backing ESP Laboratory (B.A.B.E.L.) for the purpose of appraising, identifying, nurturing, and protecting espers (even if that means apprehending them as if they were criminals).
Five decades later, B.A.B.E.L. locates a trio of natural Level 7 (the maximum esper potency designation) espers within Japan and assembles them into the special esper team known as “The Children” in spite of all three having developed questionable attitudes and affinities because of the persecution and ostricization caused by the ignorant fear of their powers. Still, the question during B.A.B.E.L.’s stewardship of the past five years now becomes whether Kaoru Akashi, Shiho Sannomiya, and Aoi Nogami can be refined into young ladies.
