Jelaskan Joseph dari Daftar karakter The Familiar of Zero

Former king of Gallia and Sheffield's master as well as Tabitha's uncle. Considered to be cold-blooded amid his hunger for power, it's revealed that he killed Tabitha's father, Charles, due to the efforts to ascend to the throne, and was behind the potion that drove Tabitha's mother insane. He is also a Void Mage with the ability of 'Acceleration', speeding up his movements. He possesses the Founder's Music Box. Throughout the majority of Joseph's part in the story, in his heart there is nothing: no tears, or sorrow, a true 'Void' in his heart. The conviction is when he caused destruction in Romalia that his motive was to see if any sense of remorse is within himself. Sheffied captured Louise and hands her over to him to copy her Explosion spell, though Louise was later rescued by Saito and Tabitha. He literally dies, along with his beloved Sheffield, by a detonated Firestone after he could finally feel emotion.
