Milim Nava

""“I'm the one and only Dragonoid, also known as the Destroyer!” "."

Milim Nava (ミリム・ナーヴァ) is the daughter of Veldanava and one of the first generation Demon Lords. She's the best friend of Rimuru Tempest and serves as an important ally across the series.

Concealed Form
She normally looks like a youthful human girl around the age of twelve to fourteen, making many people confuse her as a child at first. She has glossy platinum-pink hair tied in twin-tails and blue eyes. She usually wears a rather bold swimsuit-like outfit consisting of thigh high socks, black panties, a long-sleeve shirt which only covers her chest, with the occasional addition of a large cloak.

In the kids version of Light Novel, her outfit was toned down. She wears a longer shirt that covers almost all of her midriff, a black skirt, light colored leggings, and black shoes with pink bottom.

True Form
In this form, Milim actually looks more like the Dragonoid that she is, having a crimson horn adorning her forehead and large wings. In this state she usually wears proper battle-attire consisting of jet-black armor.

Personality
Milim, by nature, is a rather childish and outspoken individual. She isn't afraid to speak her mind and throws away any pretense of formalities. This, however, shouldn't be mistaken as her having the mind of a child. Those who can look past her childish demeanor will find a fierce, extremely intelligent woman who cannot be tricked or outsmarted even by the brightest minds. Despite this intellect, her tendency to be inconsiderate of other people and do whatever she wants often results in her overlooking the complexity and importance of a situation entirely, in favor of a more straight-forward approach. She is also extremely sensitive to gossip, especially when it relates to her, and anybody that insults or underestimates her often ends up dead or close to it as a result.

Her jaded, lonely, and violent attitude has been somewhat whittled away after meeting Rimuru and spending time in Tempest. She begins to open up and makes more and more friends across the course of the series, with the revival of her sibling Gaia, in particular, filling her with immense happiness.

Background
Milim was born millennia ago as a princess of the Nasca Kingdom. She, for a time, lived a happy and peaceful life with her father Veldanava, mother Lucia, and sibling Gaia. However, tragedy struck when her father and mother unexpectedly passed away. She was well taken care of by servants, but her uncle, the king, refused to see her. With Gaia the only family member she had left, she grew up unable to remember the faces of her parents and unaware of her relation to the king. Only having each other, Gaia and Milim's bond grew more than ever, with the two never leaving each other's side, even sleeping in the same bed huddled together.

These peaceful times too, were not fated to last. A group from the Super-Magic Kingdom of the Elves had infiltrated the Nasca Kingdom and intended to take Milim and use her power as their own. Gaia stood in the way of their assailants, doing it's best to protect Milim, but it was eventually cut down and killed. Milim, having lost everything and everyone close to her, began to lose her sanity. Her mind went blank with rage as the massive power she inherited from her father came bubbling to the surface and she set out to take revenge. She made her way to the capital of the Super-Magic Kingdom and began to destroy everything and everyone in sight, starting by wiping out the castle and the King that was inside of it with a massive flash of light. In her rampage, having killed hundreds and thousands of people, she became a True Demon Lord and the resulting harvest festival brought her beloved Gaia back to life. Gaia, being corrupted by Milim's anger, took on the form of a mindless Chaos Dragon and, following Milim's command, began terrorizing the elves of the Super-Magic Kingdom. The death and destruction in Milim's wake was so destructive that the Demon Lord Guy Crimson had to step in to prevent the damage from spreading to the whole world. Guy and Milim fought each other for seven days and seven nights with no clear winner arising between the two. Eventually, the Elemental Queen, Lamrys, stepped in and managed to pacify Milim's rage at the cost of her purity.

Milim, having come to her senses, was filled with only a deep sadness. She confronted Gaia who, by her own hand, had been brought back as a mindless Chaos Dragon and decided to seal away the last family member she had left. Guy and Lamrys did their best to console the grieving Milim, with the three coming together to form the Demon Lord Council with the trio as it's founding members. Milim, for her part, began to help as many people as she could, perhaps in compense for her past actions. She slew powerful monsters and magical beasts that were attacking towns and cities and became an arbitrator for international disputes. This culminated in her discovery of the Dragonewts, a race of Demi-Humans born from the union of humans and the dragons that had spawned from Gaia's essence. As the closest thing she had to a family, she took in the dragonewts and protected them, with the City of the Forgotten Dragon eventually being built by them in her honor.

Overtime, Milim eventually grew more and more Jaded with the world. The memories of her early days had grown into a blur that she didn't care to remember and she eventually stopped interfering with the world all-together. Instead she took to the ever-growing members of the demon lord council to sate her inevitable boredom. She began to take a keen interest in strong individuals and giving them her support to join the council, with the hope of them eventually offering her a fun fight. It was in one of these plots, the puppet demon lord project that culminated in the Orc Disaster, that she discovered the existence of a certain silver-haired majin and set out to make it her subordinate.
