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.

In a world where Classes, Stats, and Levels are the everyday norm, Reivyn has a secret.He was unusually aware of his surroundings from an incredibly early age, and Skills and Stats were acquired easily. He was just the son of an ordinary village family, and nothing appeared out of the ordinary on the surface. But below the surface, dreams of another life help shape his mentality and growth. Why does he have some remembrance of a past life, and what is his purpose in this new one?“Soul of the Warrior” is what I call a Semi-Isekai LitRPG. I say “semi,” because Reivyn's past life is remembered like a dream, and very incomplete. It is still Isekai, though, as he remembers enough that it directly shapes his personality and his sense of self.The System that governs the world of “Soul of the Warrior” is a combination of modified versions from Selkie's “Beneath the Dragoneye Moons” and Kosnik4's “Magic Smithing.” I have changed enough of these Systems and combined them in a way that is unique that I'm mostly sure it's fine, but I still have requested permission to use these ideas. They have both graciously granted me permission.Winner of the April Writathon Challenge.

Reborn to a year ago.
That is – the third year of their separation.
