Doomsday: I Become Invincible By Picking Up - Chapter 6

Yamagata Tatsumi and his family were traveling in their car when a wild truck smashed into their car. But wait! The MC wasn’t dead yet, his entire family was though. With his entire family dead and relatives abandoning him, the only one remaining by his side was his pet cockatiel. For a year he lived only with his pet, who had been with him since childhood. But finally, her lifespan reached its end and she died in his arms.

An alien race invaded the Earth on June 6, 2128. At the midst of this war, many nations allied with the alien threat and the war nearly wiped out the rebelling humans of the planet. At the edge of mankind's survival, the United Nations Army launched its forces to eliminate the immediate stellar threats that loomed over Earth.

General Seeker Carlean, commander and leader of the mission, risked and gave his life to destroy the immediate stellar threat. The battle was won though Earth lay in ruins. Perhaps mankind will live to see a few years of peace before the alien threat returns to wipe out their existence.

At the immediate aftermath of the stellar battle, the fallen Seeker Carlean awakens and finds himself at aged 17, living the peaceful life he lived 16 years before he died.

So begins a new game in the battle for humanity's survival.
