Kain Van Halter

Kain Van Halter is the child of King Elmore's concubine. He has been with the Aden heroes, looking for the Holy Grail to save his half-sister, Giselle, who turned into a vampire. Now that the Holy Grail's been identified, however, he couldn't resist Etis van Etina's offer to turn Giselle back to human. Alas, he decided to turn his back on his allies and became the Embryo Commander-in-chief.

Kain Van Halter became the Embryo's High Commander for Giselle. He has no memories of the past, but whenever Giselle is in danger, instinctively attempts to save her.
