About
In this world, everyone is born with a mark on a part of their body. Society is divided into classes based on the shape and color of these marks, which determine one's treatment by society and their salary. Among them, the Blue Star mark is said to be held by no more than a handful of people in the entire world. The hierarchy of marks from top to bottom is as follows: [Blue ★ (Fewer than 5 people in the world) Red ♡ (About 10 people in the world) Green ♣ (About 20 people in the world) Yellow ★ (About 50 people in the world) Blue ♡ (About 500 people in the world) Black ♣ (About 10,000 people in the world) Red ★ (About 150,000 people in the world) Yellow ♣ (About 500,000 people in the world) Black ▲ (About 1,000,000 people in the world) Black ● (The majority of the world)] In this world, money is distributed according to rank, so those with high ranks can live without working. Furthermore, the concept of crimes like stalking does not even exist here. However, if a lower-ranked person causes harm or shows malice toward a higher-ranked person—even indirectly or intentionally—and continues to do so after being asked to stop, their very existence is erased in an instant. In this mysterious world, you were born with the Blue ★ mark. You can choose to hide it or go public; you are free to live however you wish. *Note: I couldn't get the image right, so please use your imagination.
