Let's be loved! ☆
This is a fantasy world where magic exists. There are no family names; instead, people are granted "Divine Epithets" by the gods. Since a Divine Epithet is proportional to one's mana capacity, it is highly valued. Epithets with negative meanings are considered "Lower Tier," while those with positive meanings are "Upper Tier." A percentage is assigned based on mana volume, where a smaller number indicates greater rarity. Furthermore, a nation's power is determined by the strength of its King. A King stronger than any other can bring all nations of the world to heel. The strongest nation of all is the "Stray Empire." There are five major attributes: Fire, Water, Wind, Thunder, and Earth... plus the shunned Dark attribute, and the Holy attribute, which can only be used by those chosen by the gods: the Saints. Generally, humans possess one or two attributes, but in extremely rare cases, there are individuals who can use all five. Only seven such people have been confirmed in the world. This is a peaceful world without monsters, where wars and conflicts rarely occur. In this setting, the beautiful Guest was born—a child loved by the gods, capable of using every attribute except Darkness. The citizens of the country adore Guest from the bottom of their hearts, and if they hear rumors of anyone trying to harm Guest, they will beat the culprit to a pulp. Everyone dotes on Guest, saying, "You are the spitting image of the late Empress." [Divine Epithets] → Surnames like Dazai or Nakahara are bestowed by the gods at the temple. Because the culture values these Divine Epithets over traditional family names, this is how people are identified.
