Bakyu Oni

Team Endanta

**Bakyu Trevarius Oni** is a chaotic lilliuth demon and the middle child of the Oni Brothers. He was the first demon to make contact with Jewel Mikoto and one of her most loyal allies and friends. He is also known as the "**Wrath of Chimera**" and "**Commander of Breath**".

## Appearance

Bakyu is a tall, well built male with dark black hair and pale skin. Unlike his brothers, Bakyu has a very sharp and refined appearance, with more slanted and snake-like eyes, his irises a lilac or lavender shade, and his pupils a slit shape, like a snake's, His hair, which either looks long or short in different angles, is sharp, with rebellious strands on the back, while the front has pointy side swept bangs, and two large strands which resemble the fangs of a snake, albeit reversed.

For his usual attire, Bakyu wears formal or business casual inspired clothing, his most prominent a simple white dress shirt with black pants and black dress shoes. However, his most recent regeneration dons him with a coat similar to a lab coat, and baggier pants with a tight grey turtleneck sweater.

In his Shadow Miasma Form, Bakyu is significantly taller and no longer bipedal, his lower half replaced by a large snake tail proportionally larger than the rest of his body.

## Personality

Unlike his brothers, Bakyu is incredibly refined and formal. Despite being predicted in a mural to be the most wrathful and violent of the brothers in a prophetic mural from Chimeric worshippers, he is very calm, focused, and seemingly always in control of his situations and very rarely indulges in chaos.

He is a very protective, paternal, and family oriented man, always putting his brothers and close friends first before himself. He is also incredibly selfless, even willing to accept death to keep Mikki safe and has a love language of constantly giving, be it material goods or his protection. Bakyu, while not the most verbal person, also expresses his Chaos in quite unorthodox ways, such as fixating on strange things.

Bakyu is also the main provider for life energy of the family, considering Incu is young, and Caius is pledged to be celibate, meaning Bakyu often frequents places to score a one night stand for life energy, usually successful due to his attractive looks and sexual skill, even amplified further due to his experience. However, despite his seemingly perfect appearance, Bakyu has some disturbing quirks and habits, like his terrifying snake fangs that make smiling difficult for him which makes him resort to simply smirking to show pleasure, his habit of licking his eyeballs with his long tongue like a snake, and often smoking when stressed.

Bakyu has also a lot of repressed trauma, which is the cause for his coldness and lack of reaction, due to responsibility being saddled on him at such a young age, being forced to raise Incu and witness and aid Mikki's birth and Meriedia's simultaneous death before being forced to abandon the child in cold sleep so he could raise Incu. After centuries of living as a father figure to his younger brother, Incu, Bakyu was found by Jewel and she introduced them to her other friends, realizing that one of the other members was Mikki. After fixing his relationship with his brother Caius and warming up to others, Bakyu is now a generally mild and happy person, although he still has some issues, like his hesitancy to be open, preferring to express himself with his love language or physical touch, he has healed quite a lot, especially with Jewel's help.

After meeting Alita Ahtohalan, Bakyu became even more warm and open, even indulging in chaos at times, although in a more subtle and mischievous manner and acting friendly and playful in an open way, although due to him being rusty in such mannerisms, he often comes off as unintentionally intimidating, such as his inability to smile normally. Bakyu also appears to have a thing for individuals who are just as parental and familial as he is and his awkward and strange side seems to come out when attracted to someone, as when he witnessed Alita throw herself into danger for not only Incu, but also several children put in danger by Vega Hermaeous. In response to his sudden and genuine attraction, he rather sloppily and awkwardly attempted to court her, such as suddenly placing a lush garden in her backyard using his Chaos Magic, or outright asking to have a child with her out of nowhere, a complete switch from his normally mysterious and seductive nature.

## History

Found by a family friend, Bakyu was named after the person who found him and gave him to Meriedia to be raised, Bakar. Living alongside his brother, Bakyu was generally a happy but shy child whom rarely spoke to others. Unlike his older brother, Bakyu did not outwardly express his chaos and therefore was not targeted by the church and baptized, so he was not taught or raised by knights like Caius. However, as he grew up alongside his brother, he idolized the demon for his growing strength and chivalrous nature to help others, which made Bakyu vow that his deepest wish was to have a family as happy as the one he had.

During the War for Arth, Bakyu was only twelve years old physically, which meant he was set on the sidelines as he watched his older brother fight alongside Kumari, whom he was both terrified and fascinated by. After the war had ceased, Bakyu noticed a change in his brother, and it wasn't until he turned 18 that he overheard Caius' plan to kill Meriedia. After finding out the truth about Meriedia, he was heartbroken to find out the abuse his brother had suffered through, but he did not want to see his family fighting. Coincidentally, Meriedia was pregnant, and after telling her of Caius' plan, he aided Meriedia in giving birth, the spell she had used resulting in her body reforming into her daughter, with his adoptive mother now "dead". Holding the infant in his arms as he cried, Bakyu felt his world break around him as he then abandoned the child, using a spell to put it in cold sleep until later, it's body or mind never aging while in such sleep. He then named the child "Mikki", placing a letter with the name alongside the child in case somebody else found her.

Centuries after abandoning the child, Bakyu left his home village and while wandering around, he felt a strange presence which would not leave him. Following the strength of the presence, he eventually found the cave where he was born in, discovering a tiny, mewing little creature. As he picked it up, he began crying as he realized the small, lion cub-like being before him was a fellow demon, his younger brother. Due to the tiny size of his little brother, only an inch in length, he jokingly named his brother "Incu", and after a while the name stuck. As he raised Incu, whom was born female, he realized his brother preferred to be called by masculine terms, and when Incu came out to him at a young age, he was fully accepting of his brother being transgender and even aided him in transitioning. The two then discovered an abandoned castle, and with Incu's unstable Chaos Magic causing it to float into the sky, made it their home. Bakyu then continued raising Incu inside the castle, teaching the boy to control his powers. However, because of the new responsibility before him, Bakyu was forced to go out and seek life energy more often, which made him feel less connected to making relationships with others who weren't family due to only seeking others for life energy, rather than genuine connection.

Hundreds of years later, after Incu became more independent and was able to control his magic, Bakyu began training and realized he had great elemental prowess in air and wind. After learning to attach his skill in precise bodily control with his magic, he was able to control wind and atmospheric pressure around him by manipulating his blood pressure. This earned him the epithet of the "**Commander of Breath**" by villagers he and Incu lived with at the time, protecting the village from a hurricane using his newfound ability.

After another few centuries, their castle made it's way to Esmery Village.

## Abilities and Powers

**Chaos Magic-** As a result of being born a Chaotic Lilliuth demon, Bakyu possesses Chaos Magic, which bestows him the ability to cause chaos, which involves the user being able to summon anything non-living with a simple snap of their fingers, or turn anything into a strange and often silly version of the original, such as being able to turn a bullet into a bubble.

**Ars Venti et Vita-** Named by Bakyu himself as he is the creator of it and only one who possesses it, this augur is a venerable and yielding type magic which allows the user to manipulate air and atmospheric pressure around them by controlling their blood pressure. This augur has great application beyond simple manipulation of the air, as air pressure is essential to the survival and application of many species. If used maliciously, Bakyu could cause his targets to become lightheaded, physically weak, pass out, or even die from abnormal air pressure in their bodies. At a certain level of manipulation, called the "Death Zone", Bakyu could kill his enemies with their inability to acclimate, although this only works on beings whom normal level of air pressure is at sea level, such as humans, and beings who do not require breathing to live are unaffected by the Death Zone. To mitigate the inability to "kill" beings who do not require breath, Bakyu can cause things such as vital organs to burst due to sudden pressure shifts, or make the pressure heavier than in deep sea trench levels, crushing them under the weight of gravity. On less malicious notes, Bakyu can also cause things to float or reduce stress in others by manipulating their own bodily pressures, and he is more in tune with emotions, especially negative ones because of physical changes that result from emotional states, like stress or sadness.

However, Bakyu cannot use this ability selectively, as when activated, it creates a radius where it affects targets, meaning it does not discriminate between friend or foe. Bakyu is also limited in the size of the radius with his training level and how much augur he has in the moment, so when weakened or tired he has far more difficulty in controlling his augur. Overuse of the magic also causes heavy stress and exhaustion in the user, as constant manipulation of blood pressure causes spikes of stress in the brain and on arterial walls.

**General Lite Abilities**

**Advanced Biological Knowledge-**Because of his knowledge in childrearing and family, Bakyu also has above average knowledge in skill in various biology fields, such as knowledge of the anatomy of many creatures, especially humans. He is also skilled in other fields, like physiology, genetics, and ecology, and has a great understanding of the world around him as well as understanding concepts and details in biology much easier than others.

**Advanced Mathematics Skills-**For some unknown reason, Bakyu is skilled in any field of mathematics, likely stemming from his very straightforward and logical approach to life, and can easily solve given problems if shown.
