Seia

History
Born Seia Marcia Tulia Honoria in 323 BC, Sierra was the daughter of a trader who operated out of Tyre. She was also a "High-Spec" human, people born with high levels of spiritual energy that allowed them to see and interact with spirits. While most women took a back seat to the male-dominant society in Phoenicia, Sierra's father groomed her to be a merchant like himself and she eventually became an active member of his business, often times taking on the role of an accountant. In 290 BC while Sierra and her father were sailing across the sea, their ship capsized suddenly and much of the crew drowned before they could escape the water, Sierra included.

She awoke in Soul Society where she was given a ticket that assigned her to the 67th South Rukongai district. Much of her first months in the Rukongai were spent searching, for her father, the lost crew, or anyone that she knew in a vain attempt to deny the fact that she was now dead. As time past she resigned herself to the afterlife that she now found herself in. While the 67th District was nothing to be overly proud of, Sierra eked out a living as a merchant with a modest little store converted from her home. Frequent attempts of theft led her into fighting however, and with her higher than normal spiritual power, she quickly became a force to be reckoned with in Southern Rukongai. Crime decreased a notch in the areas nearby her home, giving her friendships with the hard pressed innocents of the 67th District and a degree of infamy with the rabble that constantly kicked up trouble. Her power and antics didn't go unnoticed however with the Shinigami eventually seeking her out and offering her the chance to join their ranks. Initially she refused on the grounds that the Shinigami, who were supposed to govern the Rukongai, were doing a terrible job but her decision changed when she thought about the things she could do from within the Seireitei. It would take several years, possibly hundreds, but she was dedicated to the idea of gearing the Shinigami into proper protectors of the Rukongai Districts.

Thus she began her training as a Shinigami. In a time before the opening of the Shin'ō Academy Sierra's training was handled by a single Shinigami, Arthur Callaghan. Together they went through the lessons of Hakuda, Kidō, Hohō, and Zanjutsu. They often went on missions together in order for Sierra to get a grip on ther techniques in both practical application and tense situations, when Arthur believed he had taught Sierra all she needed to learn he gave her a final lesson, that of awakening Shikai. The pair took to a small lake on the edge of the 40th Eastern Rukongai where they began sparring against one another until Arthur elevated the fight by aiming to inflict fatal wounds on Sierra. The dual quickly escalated until Arthur caught Sierra by surprise with the use of Iron Palm which knocked her out when her head smashed against the ground.

Awaking not long after, Sierra found herself on a ship surrounded by water where she was soon confronted by a wolf that could talk. The pair talked at length before giving their names to each other, but as the wolf addressed itself, Sierra found herself unable to hear the words at spoke and asked why. The wolf explained that she would have to discover her own power before she would be able to understand the name behind it. Before Sierra could ask about it numerous ships appeared from nowhere and one-by-one they were being eradicated by lightning bolts. Taking the supposed hint, she started searching the various ships for somekind of "power" before stumbling across a casket within one such ship. Opening it she found the hilt of a sword which caused her to wake up the moment she touched it.

Back in the Rukongai she found that her zanpakuto had broken with only the hilt remaining though Arthur told her to speak the name she was given. Almost instinctively she spoke, Nichiyō no Hōsoku. The empty hilt transformed into a two-handed sword as a result of the name being spoken. Arthur congratulated his pupil on awakening her Shikai and told her that her training was complete.

She was formally inducted into the 6th Division where she worked diligently for several decades, often patrolling the Rukongai vigilantly whenever she wasn't off stamping out Hollows in the Living World. As time went on she convinced other Shinigami to pay more attention to the Rukongai Districts.

Within the next few hundred years Sierra had become a very popular Shinigami, after unlocking her Bankai she was made the Lieutenant of the 13th Division following the death of the previous one and her efforts to aid the Rukongai, especially with Shinigami that hailed from the more poverty-stricken areas, only made them look up to her further. As could be expected Sierra would go on to become the 13th Division's Captain. It was now that her duties began to noticably pile up to the point that she could rarely even think about the Rukongai let alone visit it and so she left it in the care of other Shinigami while she dealt with Seireitei-centric matters, the Hollows in particular.

Her methods for dealing with them were none too kind, having witnessed several deaths of fellow Shinigami at the hands of Hollows, she consistently treated them in kind though she still cleansed the creatures with each one slain by her zanpakutō. Around this time she met Jojishi Kyōjin, an enterprising member of the 12th Division who had been working on a device that would allow the Shinigami to enter into Hueco Mundo.

When the device was completed and Jojishi proved it could work, Sierra called a meeting of the Captains to discuss its potential, she advocated using it to storm Hueco Mundo and bring the Hollows under proper control, though her view was one of the least popular among the other Captains it would eventually gain popularity amongst the other Shinigami when her plan became public. This created a schism between the Gotei 13, those in favour of the plan and those against it. Though initially opposed to go along with it without the approval of the entire Gotei 13, Sierra was convinced to go at it regardless and took her supporters with her in an invasion of Hueco Mundo, they left quickly after the movement had "apparently" died down, allowing them to avoid interception by the rest of the Gotei 13, though they quickly became aware once it had set in motion.

Sierra and her followers fought limited skirmishes against small bands of Hollow on the surface of Hueco Mundo, such scattering made them over confident which led to their down fall upon storming the Forest of Menos. Surrounded by Menos and Adjuchas-class Hollows, the army of Shinigami was slaughtered and eventually only Sierra remained. She would continue to do so for as long as it took, becoming a legend amongst the Hollow as a mysterious hunter that cut down anything that got in her way. In the mean time much of the Seireitei would forget aboout Sierra and her actions, as Visored were created and Sōsuke Aizen entered the center stage with his Arrancar army. Following the battle of Las Noches, Sierra found herself a way out of Hueco Mundo and returned to Soul Society where she expected to be sentenced to exile, if not worse.

Instead she found that the Shinigami had forgotten her, and those that hadn't didn't see any point punishing her further after her time spent trapped in Hueco Mundo. Essentially forgiven, Sierra became a Shinigami in full once again as lieutenant for the 9th Division.

Powers & Abilities







 * Enhanced Reflexes:


 * Enhanced Durability:

Zanpakutō

 * In its sealed form, Sierra's zanpakuto takes the form of a two-handed Jian with the typical guard and a purple tassel attached to the pommel. Its hilt and sheath are white in colour.
 * Shikai: Upon calling out the release command Nichiyō no Hōsoku begins to glow for a moment before shattering with a new sword taking its place. The Shikai form of the sword is in the design of an Executioner's sword with a short quillon and no blade tip as well as a pear-shaped pommel. The hilt, like its sealed form was white in colour. An Executioner's sword was designed entirely around decapitation which was why it lacked a point, though as the only gauranteed way of killing a Shinigami without extensive combat was to cut off their head it remained a frightening tool nonetheless. The sword glows lightly and upon contact with the enemy latches a static charge on to them which can be used to call down a blast of lightning on them, the strength of the lightning bolt depends on how many times the sword has made contact with them, in most cases it takes five hits before a fully powered lightning bolt can be used.
 * Bankai: Zettai Nichiyō no Hōsoku (絶対日曜の法則, Absolute Law of the Sun): The Bankai of Sierra's zanpakuto, when released no immediate physical changes take place until a series of light-blue lines appear across Sierra's body. The Bankai creates a massive thunderstorm in the vicinity of the battle which covers a radius of ten kilometres. Sierra can call upon the lightning generated in the above storm for various effects such as empowering her sword with electricity or blasting a target with a beam of energy in the form of a wolf's head. She can also call down lightning bolts on top a target directly to try and destroy them that way.
