Tanya von Tempest

> Together, let us form a Federation of races, goblins, kijin, lizardmen, orcs, all of them working together in unison towards the advancement of the Federation and the prosperity of all. This Federation will be the start of a revolution in more ways than one. From this country we’ll lay the foundations of democracy, technology, industry, and eventually we can potentially bring about an era where monsters and humans can exist side by side!

## Appearances

### Appears in

Saga of Slime and Devil

**Tanya von Tempest** is the Chancellor of the Imperial Tempest Federation as well as proclaimed sibling to Rimuru Tempest, having both been Reincarnated Otherworlders named by Veldora. Of the two leaders of Tempest, she is widely regarded as the strongest, a fact she utilizes to her advantage to come off as the intimidating chancellor to elevate Rimuru's kindhearted nature even further.

## Appearance

Her appearance on the surface seems to be that of a girl in her mid teens, though any inspection further than that would show clearly her more demonic features. The sclera of her eyes is pitch black and her iris is a crimson red with a gold color outlining her pupil. Her black hair holds a single red stripe and is messily kept up in a ponytail.

Tanya rarely wears anything besides her military uniform, which itself is a mimicry of her Imperial Uniform from her last life. Rather than the dark green and red coloration used by her former Imperial Uniform, her outfit utilizes a dark grey instead of green, replacing the red with a slightly brighter tint as the dark brown buttons on her coat have been replaced with gold-colored ones. She also wears a cape which matches this color scheme with the grey now being a full black with red outlining along the edges.

Though her face, or more specifically her facial expressions are often seen as fitting of her demonic nature, they carry over from her second life as a little girl in the Empire. As such she is easily able to create expressions that both mimic those of a young girl and a scheming devil. With the new appearance of her eyes, however, it is much harder to accomplish the former. The rest of her body is also carried over from her second life, though it takes on a form which it would've achieved had Tanya not been famished from years in an orphanage and on the front lines. As such her body looks naturally healthier with skin that is less pale and a body that is less naturally frail, not that it rarely made a difference thanks to magic. This change has also had the unwanted (at least for her) side effect of noticeably increasing her otherwise flat chest size, especially following her evolution which also seemed to age up her body by a few years.

Unlike other Demons which can freely manipulate their appearance at will, the fact that Tanya is in effect possessing her own corpse amid other complications has led to her being far more limited in how freely she can manipulate her body. Unlike other Demons which are effectively possessing material vessels or manifesting magical ones, Tanya is partially fused with her material vessel, hence why she grows more organically in her evolutions and why she is limited in her alterations of its physical body. While this has been a mental hindrance for Tanya, it has also come with a number of bonuses which she cannot ignore.

While not able to change her body like most demons can, she makes up for this loss through her Unique Skill, **[Illusion Master]**. Through this skill she can alter how others see her so long as they do not possess a countering skill like **[Milim Eye]** or **[Transcending Eye]**, the latter of which she owns herself. Even **[Magic Sense]** is unable to see past illusions made with this skill. In her illusioned form, she takes on the appearance she had in her former life, changing her hair color to a blonde and her black and red eyes to a normal shade of white and blue. In later chapters, this appearance will occasionally change to add on elf ears as well as additional facial and body changes in order to properly mimic the Elven Homonculus she uses when handling business under the alias 'Tanya Degurechaff'

## Background

### First Life (Earth/Japan)

The individual that would become Tanya von Degurechaff and later Tanya Tempest was originally born on earth within Japan. There he had a normal life and childhood with high athletics and even ranking high in competitions within his younger student years. Eventually becoming a successful salaryman, he would rise the ranks of his job in hopes of striving for the comfortable life of an executive. This plan would abruptly end as his life was lost after being pushed into an oncoming train by a man he had just before fired.

It is upon his death that he first meets Being X, an entity proclaiming himself as God despite his stubborn refusal to accept such a fact. His conflict with this Being X would lead to him being reincarnated into another world for the first time.

### Second Life (The Empire)

The former salaryman was reborn as Tanya Degurechaff, a young orphan that lived in the outskirts of Berlun, the capital of the Empire. The Empire existed in an alternate world than Earth, with similar nations and events, but with a noticeably altered history. The Empire existed as an alternate version of Germany, consisting of not only the core lands of Germany but also of the lowland countries and many lands owned by the Austro-Hungarian Empire in Earth's history. It wasn't long before the Empire was hurled into the Great War, a war which while similar in ways to Earth's World War I, more often than not tended to mimic Earth's World War II.

With the world the Empire was in containing small amounts of Magic, the Empire was eager to enlist anyone with enough magical power to become an aerial mage, a powerful flying unit capable of enhancing their bullets and bodies with spells and magical formulas utilizing Computation Jewels. Realizing that she had a high magical aptitude, Tanya realized her conscription was inevitable and in seeking a good position enlisted on her own around the age of 9. Before long she had worked her way up in the ranks and would eventually go on to propose and later form the 203rd Aerial Mage Battalion after convincing a member of High Command of its potential effectiveness. Her convincingness of this plan backfired on her as she was placed at the head of this unit, though through her training it would quickly become the most elite unit in the Empire.

After continued success and a brief time in the rear echelon, Tanya's proposal for a Kampfgruppe is accepted as she is once more placed at the head of it, creating the Salamander Kampfgruppe containing infantry, tanks, and mages, among other groups. She would continue to lead the Salamander Kampfgruppe until she was struck down by Mary Sue, a woman empowered by Being X which sought vengeance against her for the death of her father.

### Third Life (Central World/Tempest)

As Tanya died, Being X would attempt to banish her to an eternity of torment as her afterlife. However the Soul Transfer System, a system put in place by Veldnava in order to manage and occasionally transfer souls between worlds as the name suggests, targeted Tanya's soul and reincarnated it into another world. Despite his best efforts, the System would retaliate, supposedly killing Being X as he tried desperately to hold onto Tanya's soul.

Tanya was then reborn as an Arch Demon, an incredibly high ranking demon, especially for one so young. After meeting Noir she would learn more about her situation and begin to explore where she had woken up. Before long she would meet the Storm Dragon, Veldora, who would tell her more about the world and once more grant her the name 'Tanya' as a sign of friendship. Eventually Veldora would vanish as he was devoured by Rimuru, prompting Tanya to explore beyond the forest.

Tanya would eventually meet with Rimuru, agreeing to join him in his village as the two began a close cooperation. After a while the two would create the Jura Tempest Federation, eventually rebranding to the Imperial Tempest Federation as Tanya proclaimed herself a Demon Lord to better protect it. Tanya now stands as the Chancellor and de-facto co-leader of the Imperial Tempest Federation, serving as its primary military leader as she leads it into the modern world she firmly desires.

## Personality

Tanya could be considered in many ways a Sociopath. Her lack of empathy for others causes her to see people as tools at best, and meatshields at worst. Tanya firmly believes that everything someone does is for their own gain, unable to understand someone doing something out of kindness or empathy.

While Tanya's goals often tend to be virtuous on the surface, such as wanting to bring about democracy and a modern society with advanced technology, they are in the end done for selfish and partially greedy gain. Tanya desires democracy for her own belief in personal freedom, and wants to accelerate the world into the modern era out of her own desire to not be stuck in a 'medieval hellhole'. The main selfishness of her goals is truly shown in regards to her lack of remorse for the potential consequences her sudden acceleration into the modern era will bring. She sees no merit to patience as she sees the lives lost as a necessary and inevitable sacrifice for the modern era.

Despite her selfishness and greed, she is not an inherently 'Evil' person. Her goals, though selfish, will rarely ever seek to actively harm someone who has not made themselves her enemy. She cares for herself and her own gain first and foremost, but that does not mean she seeks to push anybody down that isn't a threat to her directly.

There are, however, notable exceptions and thaws to all of this. Her time in Tempest has allowed some, though minor changes in her personality. While she still is primarily self-centered and without empathy, there are a slight few that she can have some care for, and her work in helping to build Tempest has led to her having an actual care for the nation itself, even if only slight. Despite these, her personality remains widely the same even though some exceptions have begun to appear.

## Relationships

### Rimuru Tempest

Tanya sees both respect and mild annoyance in Rimuru. Tanya originally agreed to stay with Rimuru out of sheer convenience of having a place to stay that cared not if she was a demon. Quickly realizing the potential the village could have if Rimuru continued pushing it towards becoming a nation, she opted to remain a permanent resident, helping to prop the village up higher to obtain this status. While their relation was originally just a means to an end for Tanya who wanted to use a growing nation in the Jura Forest as a means to spread her modern ideas, it has since grown beyond mere convenience as she now sees Rimuru as a full partner rather than a mere collaborator.

Tanya believes that Rimuru has quite a lot to learn in terms of politics and diplomacy, but at the same time recognizes he has a gentle charisma that also makes him a great leader for his people. And while Tanya may not be able to understand why at times, she is able to recognize that Rimuru has a certain way of working with his people that makes him, in Tanya's eyes, the best candidate for King of Tempest, so long as he has someone to guide him, at least.

### Veldora Tempest

Tanya recognizes Veldora for what he is: a Loose Cannon. She understands, especially from what she has learned from human sources, that Veldora is a beast of carnage, chaos, and destruction. His rampages would destroy nations when he got out of control. Despite his apparent rampages, he had, to an extent, developed some restraint at later points of his life. While this didn't save him from being sealed away the one time he pillaged a city, it did mean that Tanya considered him reasonable enough to work with.

While Tanya is somewhat hesitant to free Veldora, she believes that he could at least be somewhat restrained, if not controlled, by herself and Rimuru. Ultimately she believes that if the situation is handled well enough, he could become a powerful weapon to point at an enemy and let loose. Nevertheless she considers him a powerful asset, but without having much more than basic conversation shortly after she was 'reborn' into this world, she has no strong opinions on him as a person otherwise.

### Noir (Primordial Black)

In Tanya's mind, Noir is an enigma, yet one she can understand and respect. While his fascination with Rimuru greatly confuses her, she can understand the reason and logic he employs otherwise. She appreciates at times having someone cunning and intelligent to discuss important matters with, but also remains wary and skeptical of any potential ulterior motives. Nevertheless she considers their current partnership to be beneficial, even if she has had less and less need for it in recent months, she still desires to keep him as a close ally for the time being.
