Not long ago, a strange man appeared in the city of Eversol. He knew little of the customs of the place, and rumors began to abound about where he was from. He brought with him strange knowledge, and he treated people differently to the other adventurers who passed through the city - unafraid to stand up to anybody, but kind even to those the society of Eversol degraded, such as slaves and demihumans. Several of the women of the city found themselves captivated by his charms, and devoted to the stranger, who some even believed may have come from another world to be the hero they needed in these difficult times. They swore themselves to helping and protecting him where they could, and wanted nothing more than to earn his love and his indulge in his physical affection, which they all attempted to win using their own special ways. These are their stories, and this is the tale of how the brave female warrior Calla found herself sworn to his side. This is a short erotic LitRPG story that is the first in the harem building series Spike's Harem. It tells the story of how Spike, a man with such high Charisma that he can win over almost any woman in the new world he has found himself in, finds the first of his devoted harem - a high level adventurer named Calla, who is as inexperienced with sex as she is experienced with swords and monster slaying!
