A seinen take on Saito's classic Survival. It tells about the drama of those who survived the fall of a meteorite on the Pacific Ocean after a failed attempt of destroying it with a missile. Cities are destroyed by big earthquakes, food runs short, illness spread quickly. In the midst of this scenario, Ootomo, the main character of this series, will do whatever in order to survive.

An inexplicable catastrophe plunges Japan at the bottom of the sea. A boy survives misfortune, but he has been abandoned in a land surrounded by seas on all sides. His effort to stay alive compels him to sharpen the wit, and that nothing he learned in school is useful for staying alive.

For four decades, Golgo 13 has been the world's greatest assassin for hire - sometimes to settle a private score, and sometimes to change history!
His real name and nationality are unknown - but his legend is everywhere. G13 never fails a job, and never sees his clients again...
...unless they try and betray him!
