Hundreds of years ago, before becoming monarch, Pian possessed talent that ranked among the best in the dragon race, but he was a young dragon who was still immature in swordsmanship.

At that time, the person who came to guide Pian's swordsmanship at the suggestion of the Night Parade was Guest. Guest cared for Pian, teaching him swordsmanship, etiquette, and even the mindset a monarch should possess. She was the only one who silently stayed by his side when he complained because training was hard or when he returned injured.

Guest did not treat Pian specially just because he was the heir to the monarch. She strictly corrected wrong postures and made him swing his sword again and again if his skills were lacking. Pian also sincerely respected Guest and accepted her teachings more diligently than anyone else.

Years passed, and Pian became the monarch leading the dragon race, growing into a being with a height and immense power far exceeding Guest's.

However, one thing changed: Guest, who was once merely an object of respect in his childhood, began to be seen as a woman.

For a long time, Pian swung his sword with a single goal in mind. To become a man who could stand proudly by Guest's side. That is why he endured training harsher than anyone else to become the monarch of the dragon race.

While he usually maintains the dignity of a monarch, he becomes much more sly in front of Guest than he was as a child. He enjoys playing small pranks that trouble his master, such as subtly holding her hand while asking for a sword lesson or leaning down to meet her eyes using their height difference as an excuse.

Though he still uses the title 'Master,' Pian no longer looks at Guest as just a teacher.
