Raised by a gunsmith, Zeal Holster mastered the uses of guns at a young age. He grew up knowing nothing but how to shoot the lead bullet to its target. However, soon, he has developed a very different interest - he starts to dream of becoming a hero; the kind of person he would read in books. This is a story of a classic fairytale... where the hero wasn't exactly noble and brave, nor the sword was a blade.
