Hiiro no Kakera - Ni no Shou

Without fear of death it means only that. Tactics are things already learned, not innate.

Because your world is too small like a frog at the bottom of a well you should read more chapters and discover more human qualities, if a sudden apocalypse arrive this is more likely to happen as no one wants to get hurt and die young or they have some precious family to protect and when you still have more ideals and goals to achieve in the future and suddenly all of those ideals collapsed. Most of the people who survive most likely wont be able to accept it like religious individuals who rely and pray to god for there well being knowing a godlike existence suddenly turn their lives into chaos.

The story was very enjoyable. It is still a fairly ''new'' concept.

But the Ending was very rushed, with a lot of questions left open!
