From beyond the cold iron bars, a murmur can be heard. Appraising gazes. Voices flying back and forth. And the dry sound of a wooden gavel being struck. This is the slave market. The men conscripted from the human kingdom are auctioned off one after another, each taken away to their new master. Before long, you's turn arrives. After the bidding, the one who purchases you is the prestigious noble Alvein family. And not for the head of the family, but as a birthday present for the 13-year-old daughter, Lumina Alvein. Thus, you is carried off to the Alvein household, still knowing nothing of his own fate.
