“Blood does not lie. However, it does not tell the whole truth either.”
About
Hundreds of years ago, a special ability called **Bloodline** was discovered in humans. Bloodline is a magical power dwelling within the blood, and its attributes vary from person to person. Most people possess ordinary bloodlines, but a very small minority are born with special high-ranking bloodlines. And then, there exists a bloodline that should never have appeared in history. 「Origin Blood」 The first blood, the source of all bloodlines. It is said that one who possesses Origin Blood can sense the bloodlines of others and use the powers of various bloodlines through their own blood. The problem is that the very existence of Origin Blood is taboo. Grades of Bloodline * Common Blood — Ordinary bloodline with no special abilities * Ability Blood — A bloodline capable of using specific abilities * Noble Blood — A bloodline with rare attributes and powerful strength * Royal Blood — The highest grade of bloodline, of which only a few have existed in history * Origin Blood — An unknown bloodline that is the origin of all bloodlines Bloodline Attributes 🔥 Fire Blood Manipulates heat and flames. Possesses strong offensive power. ❄️ Ice Blood Manipulates cold and ice. Specializes in defense and control. 🌑 Shadow Blood Manipulates shadows and darkness. Excellent stealth and mobility. ☀️ Holy Blood Manipulates light and vitality. Specializes in healing and purification. 🌪️ Wind Blood Manipulates wind and air currents. Possesses fast movement and detection abilities. 🩸 Hemo Blood Manipulates one's own bloodline itself. An extremely rare and dangerous attribute. ✦ Origin Blood No specific attribute exists. Instead, it reacts to the power of other bloodlines and possesses abilities that have yet to be revealed. Major Factions Bloodline Management Bureau A state agency that registers and manages bloodline users. On the surface, they protect people, but they strictly conceal records regarding Origin Blood. Blood Kin Society An alliance of families with powerful bloodlines. They value the purity of lineage and are searching for the successor of the Royal Blood. Red Blood Syndicate A secret organization advocating for the free use of bloodlines. They seek to expose the truths hidden by the Bureau. Bloodless Cult A group seeking to eliminate all bloodlines. They believe that bloodlines are the cause of humanity's corruption. Bloodline is not just a simple ability. Bloodline holds memories. The more powerful the bloodline, the more faint traces left by past users exist within it. People with specific bloodlines sometimes feel memories or emotions that are not their own. And within the memories of Origin Blood, the origin of the world and the reason bloodlines were born are hidden.
