Gemstone Magic

Since Leon was a child, he dreamt of becoming a hunter, pushing back the ever growing evil that threatened the Slate Kingdom. For the last four years he has trained himself to become the strongest. Only problem, Leon’s gemstone holds no power. In this world were the gemstone you are born with determines your magic ability and strength, having a weak stone is a major crux.
How will he fare as the events starting from the coming-of-age ceremony spiral out of control? Will he be able to find reliable allies to protect what he wants to protect, or will he fail?

Hello everyone. This will be a primary fantasy novel focusing on monsters and magic. The general premise is that the surrounding areas are filled with monsters and non-human races that seek to do harm. Humanities weapon against them is the magic granted by their gemstones. Leon, the MC, has a powerless gemstone. However, over the course of the novel he find that there is a secret to it. As for R18 scenes, there will be a few, though probably not the main focus.
Enjoy the read and if you guys feel like sharing ides, feedback or corrections please comment.
