Had hopes, turned shit south quick, don't read, I'll give you the only interesting idea of the manga:
Long hair top and stutterer bottom search for habitable planets in the Universe, then transfer some life to them with the hopes of increasing life's chances.
Also, atomic bomb scene was kind cool though, also, now I've come to understand that japs hate USA's power over them, and hold a grudge over Hiroshima and Nagasaki.
