There was once a tale, going around the Land of Dawn about a musician. No one ever knew where he came from nor where he was headed. Everyone just called him the vagrant poet, Granger. Granger was orphaned during the war between the Moniyan Empire and the Southern Mountains. He was picked up by the Imperial Army, and then sent to the Monastery of Light. Similar to all orphans, Granger was silent and isolated, however, music and firearms became his only and most loyal partners. During his growth, Granger became a Demon Hunter like Alucard. It's said that his gun speed and bullets have exceeded anything, far beyond one's imagination, especially the power of the last bullet of his magazine, which explodes, upon contact and causes enormous damage.

Since a young age, Granger enjoyed music very much. He would instantly turn a beautiful piece of music into a battle song, and the ups and downs of music, often made him excited. Soon after, he took the lead among the demon hunters and even the S-Level Tasks were not a big deal to him. Impressed by his efficiency and abilities, Alucard, one of the most well-known demon hunters, admired and respected Granger. In order to pursue the pleasure of killing enemies and completing tasks quickly, Granger would often give the most fatal attack to his enemies. The bullets were like secret orders, chasing the enemies, just as Granger's assumption. When all six bullets of his magazine, hits the target, the fallen enemy could feel the horror of Granger, before slipping away into oblivion.

Everyone the Monastery of Light knew that Granger abhorred war and demons, to which he lost his family and home, thus he wouldn't hesitate to be a hunter. Violins, however, meant a lot to him, as they soothed his misery and nightmares. Since Granger held a gun for the first time, he had consistently exceeded expectations in both practice and actual combat. He was a perfectionist in both solo combat and teamwork. Granger remains one of the strongest men in the Monastery of Light, with great combat techniques and a strong, advanced sense of avoiding danger.

The news about Granger soon spread among the demons. As long as they heard a horribly sad melody, they would escape with haste because this could most likely be his Death Sonata, specifically designed for the demons. So every time the sonata ends, there will be a demon defeated and Granger is an opponent that no one wants to meet. Not only is he good at hiding, but also is he proficiently good at shooting, from a great distance. Burst shots at close range and precision shots from a distance are the most common ways for Granger to attack. Naturally, he is considered as the Invicible Shooter/Marksman in the Land of Dawn!
