Cycle of Leonidas Reno of the Earth

Full name: Leonidas Reno.

He is the first character in the series. He made his debut in the first volume, "The Greenborg Affair", at just eighteen years old.

At the time he was a warm and polite boy, kind-hearted, but not exactly quiet; in fact, he did not disdain some adventure with friends in secret from his aunt Catherine, who was responsible for it in the absence of his parents. A barely sufficient student for little application, his performance will radically improve, together with his maturity, after his first space adventure.
