About
An exchange student from abroad came to the palace. Upon hearing that the student was a prince from Zaidera, Sei started to panic, thinking that his arrival might have something to do with the Zaideran ship captain she recently helped in the port city of Morgenhaven. Although Sei had done this in the name of helping someone, she had given the captain one of her special high-grade potions, which weren't available for sale to the general public. She feared that this good deed had come back to haunt her. However, the Zaideran prince's objective wasn't the Saint at all. Rather, he hoped to learn about the Kingdom of Salutania. He was the son of the emperor's seventh concubine and the eighteenth imperial prince.

Appearance

Summary
Prince Ten'yuu is the prince that came from the Zaideran Kingdom in order to help find a cure for his mother's sickness. Prince Ten'yuu's mother was a concubine of the Zaideran emperor. She she had suffered from an illness for a long time. The prince had come to study in the Kingdom of Salutania to search for a medicine that could cure her.

The commoners of Zaidera typically practiced monogamy, but the emperor and other noblemen took multiple wives. The higher a man's rank in society, the more wives he could claim; supposedly the emperor had thousands. The more wives one had, the more children one could produce. The current emperor had over forty altogether, and Ten'yuu was the eighteenth prince among them. Only men could inherit the throne, but Ten'yuu was low in line of succession, since he had seventeen older brothers. Additionally, his mother had been the daughter of a low-ranked noble whose family had no real power. She was currently considered the emperor's seventh wife, but she had originally held far less prestige. She had only risen after giving birth to Ten'yuu.

Sei Takanashi
Sei was especially careful to avoid the Research Institute of Medicinal Flora whenever the prince visited it, but on one unlucky day, he accidentally happened upon her. Through Sei's conversations with the prince, she learned that he was searching for a medicine that would aid his ailing mother. Using her knowledge from her life in Japan, Sei managed to successfully create a panacea: a potion capable of curing every kind of status effect. The panacea was given to the prince, though the kingdom kept the identity of its maker secret.
