Locke the Superman

Colonel Yamaki is looking for Locke, an ESPer with powers are far beyond imaginable. He is supposed to enroll him on a mission to investigate Lady Kahn, a millionaire tycoon who is raising an army of female ESPers for an unknown reason., Using his esper abilities, Locke can learn and do most things more quickly than a normal human. His power also allows him to remain eternally young, or even turn himself into a child again to be adopted by kind-hearted families. This is called "waka-gaeri". It could be said it keeps him young at heart.
