Luciola (Λυξιολα) (ルシオラ, ) is a member of the Guild and personal bodyguard to Dio Eraclea. He is an exceptional martial artist. He was assigned the role of protecting him from a very early age, and Dio considers Luciola not just a servant, but also a friend. Luciola is forced to betray that trust out of fear of Maestro Delphine Eraclea when Maestro ordered him to bring Dio back before her. Luciola then redeems himself by helping Claus, and Alvis and Dio escape from the grasp of the Maestro. In a confrontation against the Maestro, Luciola kills his brother, Cicada, and is then disintegrated by a device (a ring) that is given to him by Maestro Delphine as a "gift."
Luciola's seiyū in the original Japanese anime is Tomoe Hanba, and he is voiced by Mona Marshall in the English adaptation.
