Ryousuke Akiba calls himself ES, a code name taken from a mysterious scientific experiment. Ryousuke will live to be at least two centuries old and possesses strange mental powers: He can enter people's minds, discover their darkest secrets, even rearrange their memories so that complete strangers will treat him like family.

But is he the only one? (Source: Del Rey)
