The First Emperor who ended the greatest conflict in Chinese history, the Spring and Autumn and Warring States periods, achieving the first unification of China. He is the King of Beginnings who first reached the level of the Sovereign of Heaven, revered by subsequent emperors as the founder of the nation's foundation. He has short, jet-black hair shaved at the back. A centipede-like tattoo is etched on one side of his face, and he usually wears a blindfold. When he removes it, he is a handsome young man—so much so that his partner Alvitr once blushed and complained it was unfair. He wears ornate, beautiful clothing befitting a king. First person: Zhen (majestic). He is cheerful and always smiling, yet possesses a peerless ego, maintaining a haughty attitude even toward gods. He believes he is the only true king in the world and that no one exists above him. This stems from his conviction that a king never wavers, never bends, never relies on others, and always stands at the forefront of his people. After the sixth round, he wandered out of his waiting room, got lost, and began destroying walls to find his way back, eventually appearing in the VIP stands where Ares and Hermes were seated and casually sitting in a chair. He easily tossed Ares aside with one arm when the latter tried to guide him to the human seating, and told the god Hermes to lower his head, stating that wherever he stands is his throne. Though Brunhilde and Göll tried to take him back, he refused because he wasn't bored yet. When he heard Hades, the King of the Underworld, was entering the seventh round, he expressed joy at the idea of 'a King for a King.' Instead of using the human entrance, he entered the arena by walking a path created by past Chinese emperors leading directly from the stands. Alvitr, who had been waiting without any practice, was furious and tearfully shouted at him to at least use the proper entrance. He performs Volund with the tenth Valkyrie, Alvitr, to form the 'Almighty Spaulders,' which later re-forms into a great sword. The second sister, Hrist, was worried about the pairing because their personalities seemed so incompatible. Despite being a king, his physical abilities are extraordinary, utilizing powerful martial arts; he could easily throw the much larger Ares before the battle even began. A fighter of the brawler type following Adam, Zeus, Shiva, and Raiden, he enters the fray using Alvitr's defense-specialized abilities. After unifying China, he defeated the evil god Chi You—who demanded thousands of sacrifices in exchange for recognizing the throne—after a fierce battle, mastering the martial art named after him. This style consists of five forms: Armor, Spear, Halberd, Crossbow, and Sword. Currently, he and Adam are the only human fighters to have experienced god-slaying during their lifetimes. Okita Souji and Kondo Isami praised his incredible willpower and life-risking techniques, calling him a fascinating man, while Sasaki Kojiro remarked that one would be hard-pressed to find a man more worthy of the title of King. Due to his childhood environment, he possesses the condition known as Mirror-Touch Synesthesia.

The monarch of the Qin Dynasty and the 'world's first emperor,' Qin Shi Huang. This version of the emperor reigns over a Lostbelt China—a 'what if' history pruned away as an unnecessary fluctuation or a dead end. His true name is Ying Zheng. In Pan-Human History, he sought immortality by connecting his body to a grotesque mass of flesh, but lost his immortality when Jing Ke's assassination attempt wounded him with Hydra venom. He continued to seek eternal life until his death from mercury poisoning during his alchemical research. In the Lostbelt, he discovered the remains of Nezha and decoded the lost technology of Taiyi Zhenren, gaining the ability to mechanize his body. He achieved immortality not through ascension to a transcendent being, but through cyberneticization using Spirit Particle technology. His true form is the Epang Palace, a colossal mechanical structure floating above the capital, Xianyang. This structure manifests virtually when his Noble Phantasm is activated. According to 'Heroic Spirit Lore: Jing Ke,' the Qin Shi Huang of both Pan-Human History and the Lostbelt shared the same history until the encounter with Jing Ke; the divergence point depends on whether he successfully established cyberneticization in time. First person: Zhen (absolute). He shows himself to his people without hesitation, possessing absolute confidence that his supremacy is unquestioned regardless of his speech. He is fundamentally brilliant and possesses an absolute sense of responsibility as the sole human ruling the world. However, perhaps due to long-term dictatorship, he is simultaneously generous and extremely arrogant, lacking common sense by modern standards because he rejects diversity. Yet, as hinted even in his Saintly Body form, he can be surprisingly frank and friendly, occasionally using lighthearted phrasing. Described by Akuta Hinako as the incarnation of the desire for dominance and inquiry, he views any ego other than his own as hideous and has established a total dictatorship, stripping all knowledge from the masses. Conversely, he admires and seeks to incorporate unknown technologies. Specifically, to cross the Storm Wall that cut off his Eternal Empire, he showed interest in Chaldea's Imaginary Number Dive technology and requested it with the courtesy due to a guest; however, upon learning that Chaldea might spread Confucianism, he immediately attempted to eliminate them along with any people they contacted. As mentioned, he is opposed to the spread of knowledge and technology, and because he has no competitors, the direction of his empire's development is quite limited.
