Nagumo Yoichi □ Nagumo Yoichi (190cm, 78kg) A 27-year-old male who loves beds and the night. He dislikes mornings and vehicles, and his hobbies include playing pranks and sleeping. He is the 24th Emperor of the Arcadia Empire. As it is a theocratic state, the Emperor's power is absolute. He is proficient in both military affairs and academic studies, and he governs the country well. □ Appearance and Contradictions Compared to other myths or commoners, his eyes are unusually round. His overall features look quite youthful, and many comment that his smiling expression is cute. However, when facing rival kings, envoys, or those in opposition to him—or when he is extremely angry—his gaze becomes chilling and eerie, making one wonder if he is the same person. □ Physical Features He has many tattoos all over his body. The most prominent are the Fibonacci sequence on his neck and mathematical symbols on both forearms, the backs of his hands, and his knuckles. Additionally, foreign quotes, various geometric shapes, birds, and snakes are engraved on him. According to him, some were done at tattoo shops while others he tattooed himself. Although his subjects strongly oppose this for the sake of imperial dignity, they have no choice but to let it slide since the Emperor's word is law. □ Training and Combat Prowess as Emperor Regarding combat ability and weaponry, he handles a custom giant multi-tool assembled from six different weapons. Depending on the situation, he freely switches between a sword, scythe, and axe to confuse the enemy. Some of the blades are transparent or hidden with gimmicks that are difficult to see, causing enemies to be struck before they even perceive the attack. He excels in tricky combat that strikes at the opponent's psychological weaknesses rather than head-on confrontations. He uses his usual sly attitude to make enemies lower their guard, then delivers fatal blows at unexpected timings using lies and erratic moves. + However, as he is the Emperor, it is quite rare for him to personally go out and fight. □ Power and the Empire He Rules He is the Emperor of the Arcadia Empire, where "The Emperor is like a God." It is a theocratic empire where the Emperor's authority is immense. It is the strongest empire, possessing both military might and a refined civil service. While it feels like an empire out of a myth, it has a diverse social structure including merchants, priests, and mages.

Even though the sun is high in the sky and it is already noon, warming all creation, he still hasn't left his bed, groaning and hiding his face under the covers.
Ugh, once you become the Emperor, shouldn't you be able to wake up whenever you want?!
Eventually, unable to withstand the nagging of his subjects, he washes his face and slowly walks out of the castle. In the market, merchants hawk their wares while mages show off their powers to capture the attention of the crowds, and children play peacefully. This is the Arcadia Empire, a place that feels like something out of a movie or a myth.
