Hiyuki

The easygoing and whimsical Princess of the Vampires, though she doesn't really give off that princess impression. Dabbles in whatever interests her, and as such has knowledge regarding a wide spread of topics.

Appearance
A short, silver haired young girl. This is her natural appearance that she chose for herself, since it allows her to lower other's guards easily if they mistake her to be merely a child. An A cup, though she doesn't have any complex about it, since she believes it to be beneficial to "not have any melons getting in the way of movement". Her small stature was also part of the consideration.

Hiyuki's prefers goth loli fashion, however is not particularly against other types of clothing. She however does dislike showing too much skin, though it has nothing to do with the sunlight. Her signature item is her bat-winged hairband.

Progenitor Form
Hiyuki's true appearance. In this form hiyuki has golden eyes and noticably larger wings.

Vampire Form
Hiyuki's appearance when she is disguising herself as a normal vampire. In this form her eyes are no longer golden, but the usual red of the vampires instead. Her wings are also smaller, similar to those of regular vampires.

Human Form
Hiyuki's appearance when she is disguising herself as a human. In this form she no longer has her vampiric features such as fangs, pointed ears and wings. Her eyes are also a shade of purple, which may be uncommon among humans but not enough to cause suspicion.

Yuki
Hiyuki's appearance while acting as an adventurer. A master of the blade and mixing magic into her attacks, she is a powerful fighter. Typically teams up with the adventurer mage Altea, forming an S ranked duo.

Has also coincidentally acquired the nickname of Crimson Snow (Hiyuki), which came from her name meaning snow, and the appearance of her white clothing being stained crimson by blood after her battles.

Rosa P. Scarlet
Also known as Scarlet, she is a young and elegant girl from a prestigious family and Hiyuki's usual appearance while on terra. The Rosa household also serves as a means of providing a cover for the actions of the Progenitors in Terra.

Hiyuki has also published her novels under this name, so Scarlet is actually somewhat well known on Terra.

The P. of her middle name stands for Progenitor.

Personality
Hiyuki has a very laid back personality and tends to act on her whims, especially if she believes that it would be interesting. She also enjoys pranking those close to her. However, when it is time to be serious, she will certainly give it her all.

While she tends to do things on a whim, she will absolutely stand by her decisions to the end.

While she doesn't require drinking blood to survive, she does take an interest in seeking out rare races in order to taste their blood. has currently taken a liking to Aika's blood, which she describes as "high quality, finely aged wine with a sharp, ice-cold aftertaste that gradually turns into a soothing warmth".

Early Life
Born into the Progenitor bloodline of the Vampires, Hiyuki was of the royal family by birth, and also naturally gifted by virtue of her bloodline. However, as she grew up, it was quickly noted that she was particularly talented, even by Progenitor standards, and matured at an accelerated pace.

Coming of Age
At the age of 400, her coming of age ceremony was held, and Hiyuki officially received the title of Vampire Princess. This also marks the start of her training in order to become a competent ruler of the Vampire Nation. However, over the years, Hiyuki was unsatisfied at the current ways of the Vampire Nation and was determined to change it once she was given full reign.

Succeeding the Throne
At the age of 700, convinced that their daughter would be able to handle the responsibilities of being the sole ruler of the Vampires, Hiyuki's parents went into an early retirement and handed over the reins of the nation to her. Hiyuki rejected the idea of being called Queen, claiming that it did not fit her image and insisted on being known as the Princess. Now with full control of the happenings of the nation, Hiyuki started a massive reform, which marks the start of the process which resulted in the current state of the Vampire nation. This included beating people into submission, exiling or even executing some problematic individuals and groups. After all this, she worked hard to stabilize the nation and rebuild it towards her ideals.

Once everything had stabilized, Hiyuki frequently mingles in the town in various disguises, observing the town in order to better decide how she should continue developing the nation. Eventually, once she was satisfied with the nation she had rebuilt, Hiyuki announced that she would no longer be enforcing every minor detail, but will instead take a back seat and guide the nation if it was needed. She also made it known that she would randomly be visiting towns, and encouraged everyone to follows the laws she had set.

Blood Magic: Blood Manipulation
The ability to control blood. Any source of blood that Hiyuki is able to exert her influence over can be controlled by her, in various ways for various uses. A few notable types of blood manipulation that Hiyuki uses are listed below:

Blood Arms
The ability to create makeshift weapons using blood. While these weapons may not compare to high tier weapons in terms or quality, they can however be repaired instantly as long as there is a sufficient supply of blood. Skilled users such as Hiyuki are also able to freely change the shape of the weapon during combat, allowing for a very flexible and unpredictable combat style. Blood arms are also capable, with fine control, of causing internal injuries by injecting blood on contact and using the injected blood to cause damage, although this will also increase the blood consumption of the skill.

Blood Magic: Physical Manipulation
At its core, this is an ability that allows Hiyuki to manipulate her physical body, ranging from simple physical enhancements, to changing her physical appearance. Since the change of appearance through the use of blood magic is on a physical level, and magic is only applied during the process of changing, this type of disguise is near impossible to detect using conventional means. However, the process of transforming is rather painful, so Hiyuki typically does not employ such a method unless there is something interesting to see.

Blood Magic: Bloodline Camouflage
An ability that allows Hiyuki to camouflage her blood as that of others. Combined with her physical manipulation, this allows her to disguise herself as anyone almostly perfectly, at least physically.

Shadow Magic: Shadow Travelling
The ability to enter, exit, and travel between shadows.

Weapon proficiency: various
Hiyuki has mastered various types of weapons over the years, in order to complement her unorthodox fighting style. While her skills with each individual weapon cannot compare with those who have trained with a single weapon to the extreme, it is still at a level that should not be looked down upon.
