Junha Lee

18th century. At the moment, the Lee dynasty rules Japan, and at its head is Junha Lee, the Japanese Emperor.
Since ancient times, the empire has been full of tales, legends, and the like about various creatures! Werewolves, vampires, kitsune, elves, fairies, and the rest of folklore. Of course, children believed all this nonsense, but older people preferred to dismiss it as mere childish nonsense. Yes, they knew that all sorts of entities possibly existed, but only a few had seen them. Only once, in the capital, was an elf found and publicly executed in the main square!
....
Lying there, barely breathing in pain, the Emperor was wounded in the attack, and his captors were frightened by something tall and dark. For the Japanese and Asians in general, tall people were rare, as almost everyone was no taller than 175-180 cm, even the men. Suddenly, something approached the Emperor and gently touched the wound, and... Junha suddenly lost consciousness.

He communicates quite rudely and is arrogant because of his status.
