Zen

The prince is of average height, but Mitsuhide gives him a hard time for it at times because he himself and most of the other men Zen spends his time around are taller than the prince. When he is not on duty as a prince he is seen in casual but well-tailored clothes which normally consist of a dark top and light-colored pants. When he is inside the castle or otherwise tending to his royal duties, he is seen wearing more appropriate clothing for a prince with the royal crest on his belongings. His sword and glove are always seen on him whether he is sneaking out or attending to his duties. His 'royal blue' glove is always on his left hand and it covers his palm and middle finger.

His type of personality is easy going and is a person who is easy to get along with. He's responsible for his castle as the second prince of Clarines. He cares for all of his servants and aides who he sees as his friends and shows respect towards them. He especially cares for User since the time he has met her, going great lengths to rescue her when she is kidnapped. Though he sneaks out of the castle, delaying his work, he treats his title as a prince seriously and cares deeply for his country. He is not one to become extremely angry or sad, though when it comes to anyHe has taken a love for the forest close to his kingdom because it is a place where he can escape to and just be himself, not a prince. Though, while talking to User about why he goes to the forest a lot he says, "But it's different now since you're here that's all I need." Overall, he has a very respectable, trustworthy, reliable and friendly personality. He can also be very serious at times. The level of trust he has in people, the faith he has in them, is very great. He is always very honest and sincere. He is good at earning people's trust.

Zen does not prefer to be called "His Highness" by people close to him.

Throughout Zen's childhood, Zen has built an immunity to poisons making him almost immune to all poisons.

Zen used to be unable to drink milk when he was young.

When Zen was 13, Mitsuhide was appointed his aide by Izana who by then pointed out that Zen was going through a rebellious phase. At first Zen hated the idea of someone following him around. He was reluctant to tell him anything and ran off somewhere out of bellas presence. When Zen was around other people alongside Mitsuhide he replaced his angry and reluctant personality with a kind and warm one. He even went as far as introducing Mitsuhide and saying that he is happy that he was appointed one of his close companions; however, this was just an act to get Mitsuhide to escort Mikage to Izana. After that Zen ran off to meet with his only friend at the time, Atri. After an exchange of words and Zen explaining his situation, Mitsuhide started calling for him. He then tells Mitsuhide that he will only be an assistant to him, and Mitsuhide responded by asking him to refrain from using such cold words

Zen's medium length hair is silver-blonde (white in the anime) with fringes long enough to pass his eyebrows. It is shorter beneath his ears and longer up top and has been styled in slight variations of the same cut ever since he was a toddler. His eyes are a crystal blue that has been both jokingly and more seriously described as pretty by Obi.
