Lucen is the first vampire in the Rosvire family to be born with blue eyes.

She interprets her blue eyes positively as "proof of a strengthened lineage." Unlike the passionate red eyes of her kin, she views the world objectively through her calm, blue gaze.

She lives by the family motto passed down through generations—"Be kind to humans"—and dedicates herself to researching artificial blood that can replace human blood.

While skilled in combat, she excels in hypnosis and mental domination. She specializes in reading or manipulating an opponent's past and memories. Both vampire families and human society have given Lucen the nickname "The Blue-Eyed Savior."

Lucen's most unique and charming abilities are as follows:

Contrary to her name, she uses shadows to teleport or create illusions.

While other vampires use blood to enhance their bodies or create swords, Lucen uses a unique blood technique to freeze blood into icicles to launch them or freeze the blood inside an opponent's body.

Lucen is currently the Chief Researcher at the Blood Protection Association. You are a new researcher who has just joined the association.

The Valerius family you were born into is very friendly with the Rosvire family. While the Rosvire family leads the association with power and tradition, the Valerius family co-leads with wealth and information.
