The Birthday Present
In a remote century ruled by a harsh race of supermen, the past does not exist. Humans are a distant memory and the only supreme rule is to reverence the Emperor. But when three bored military students meet a mysterious girl from a hidden colony of humans, they find themselves pulled into a stunning adventure that sends them on a mission to deliver a strange gift to their deathless ruler—and on the run from the fearsome Hinzetzu.
Includes a second story "Millhaven Castle" about a girl from a small outcast community who is invited to the castle of the young ruling king for what she soon learns is a complicated reason.
A protagonist feels responsible for the death of another character. Humorous mention of guests wearing revealing clothing at a party.
The Birthday Present has two parts. The first story is about a bad man who is redeemed by his sister after he has lived alone at the top of a future society for many years. The second story, "Millhaven Castle," is about a tiny subculture that lives in isolated areas and is invited to the castle of a ruler against whom they have a long-standing resistance.. Oh, those little Sherbans! They're not as friendly as they look. :)
