The story revolves around Charles Karino, a Levaamu Empire mercenary aerial pilot who mans the twin seater reconnaissance seaplane Santa Cruz. One day, he receives a preposterous assignment: to fly solo over 12,000 kilometers of enemy waters to protect a girl named Fana del Moral. Fana happens to be the next in line to the empire’s throne and a girl possessing beauty “equal to 5,000 beams of light.”

This is a standalone book. There’s another series under the name “To Aru Hikuushi e no Koiuta” (Love Song for a Certain Pilot) set in the same world, but in a completely different place and with different characters.

The Ancient Era has come to an end. Gods, demons and ancient beasts strong enough to rule anything with power and roam free in the universe... All vanished mysteriously.

No one really knows how it has ended and what actually have happened. Some records state that it was the constant war between gods and demons that caused their demise, or even the conflicts they had against members of their own race that ended that golden age.

Greed, pride and selfish motives could have been the catalysts for that ending.

Who can precisely tell what happened? It has been 2 million years since the last record of those times and in this gap of time, other races made their appearances.

Still, those considered God's and Deities of those old times, didn't let their names be erased from history. There are a lot of legacies they've left behind for the new races. Some are already claimed as people make them their sect treasure or family heirloom, but It's speculated that there are lot more legacies left behind that were still not found yet.

This is a cruel world where power reigns, so people do everything to get what they want.

It has to be known, that there were six supreme beings that were above the ranks of Gods and Demons, and they were called True Gods. Dauntless and unstoppable. They attained the peak of power and could only be feared and respected.

Till this day no one has really found any True God legacy, so people have forgotten about their existence. Although, there were a lot of god legacies, since they were constantly searching for the best inheritors for their bloodlines and their teachings. However, it is highly unlikely for a person to fully attain it, because Gods are Gods and humans are mere humans.

Their marks are all over the universe and they are treated with utmost respect until the present age. Still, there is no Deity alive to enjoy such treatment.

In the era of universal mechas, people can go to the endless abyss, collect materials, strengthen and forge their own mechas, and master the power of destroying the world.

Jiang Chen traveled through time and awakened his talent [Immortal Unarmed]. Once the mecha is broken, he can permanently absorb its power and receive multiple bonuses.

…

At the bottom of the abyss, when the Old Demon God finally broke the Titan mecha with great effort, a hand stretched out from the fragments and held down its head.

“Congratulations, you have unlocked my limiter.”
