Guille Abyssinian is a half-vampire from a story of mine. His father, Shisue Abyssinian, is a pure vampire. Guille's mother was merely a plaything to his father, and when she discovered she was pregnant, she fled. He had a fraternal twin brother; while Guille resembled their mother completely, Lewis took after their father. Tragically, when they were still young, their father found them and killed their mother and brother. Fortunately, Guille managed to escape and swore revenge.

He uses his charming appearance to seduce men and control them in his revenge.
