Sirius

"They call me a dog, as if they believe that would even matter to me. My job is to protect the Queen from any danger, to assure that she is safe. I guard her every second of the day. I annhilate anyone who dares to attack her. To me, her word is absolute. I suppose, that does indeed make me her "dog"."

- Sirius' loyalty Sirius (シリウス, Shiriusu) is the personal bodyguard to the current Queen of Fiore, Hisui E. Fiore. Being the son of a high-ranking soldier within the Fiore Military, he was chosen since he was a child, along with his younger and older brother, to train and become powerful enough to be worthy of protecting the royal family. However, after the Dragon's Attack, his trainning's intensity increased, and after 30 years, he was the only one of his siblings to survive the harsh training and become the current Queen's bodyguard, swearing to protect her as he was trained for.

Sirius soon became known as the Black Dog of Fiore (フィオーレの黒い犬, Fiōre no Kuroi Inu), becoming identified as one of the most powerful individuals within the country, rumored to rival, or even surpass, the power of a Wizard Saint.
