Bonchien is a young man with a pompadour-type hairstyle, similar to his father's. He has a mustache and markings on his cheeks that resemble eyelashes. He wears armor on the upper half of his body and armor on his legs that reaches up to his thighs, along with a doublet, trunk hose, a cape, and a ruffled jabot.
Bonchien is eccentric and a bit over dramatic. Occasionally, he'll go through spasms of anxiety and discomfort, yelling "stop" and "don't come near me." Despite this, he seems to be somewhat clever, being able to capture Fushi and the Defense Corps and being able to recognize Fushi despite being in Parona's form (a form he rarely took). Bonchien actually cares for the people of the Uralis Kingdom as he grew up alongside them. He seeks to find ways to help the citizens and improve the kingdom even if he wasn't the king. He has great charisma that draws people to him.
As a young boy, Bonchien was raised with the utmost care by adults as the future king of Uralis. However, his father decided he was unfit to be king and his younger brother, Torta, would be more suited.
As the prince of the Uralis Kingdom, Bonchien holds great authority and influence towards his subjects and the citizens. He has shown to have great intuition to the supernatural.
Bonchien appears to have the ability to see the dead. Most of his friends seem to be ghosts and it is hinted that he can see the spirits of Fushi's friends following him. He is able to detect and catch Fushi no matter what form he shapeshifted into.
- Bonchien appears to be closer to his younger sister Pocoa than he is with his brother Torta.
