Kozakura Hisato
She/her • Kryptis Host • Imperial Guard • Bladesworn
A permanent host for one of the Twin Daggers of House Aurkus, Ostrelen. Despite a turbulent relationship with the Canthan Empire over the centuries, she continues to faithfully serve as one of the oldest members of Imperial Guard.
A more detailed background below the cut:
History
Ostrelen first came to Tyria with Kanaxai and her twin brother, Arthelen, and also became trapped beneath the Jade Sea. As starvation began setting in, and Kanaxai turned on his company, the demon twins sought for a way to escape. Arthelen was the first to do so - an act that Ostrelen perceived to be an abandonment. Some time later, she found the presence of a human girl within inches of her life through the jade. Injured as the girl was, it was easy for Ostrelen to abandon her own body and overtake hers, even starved and weakened as she was. She wasn't aware that this had been a gift from Arthelen, but it's doubtful that she would've cared, anyway.
While nursing her new vessel back to health, Ostrelen was vicious with her survival instinct, unwilling to trust and accept help from tyrians. A string of violent attacks and strange behavior caught the attention of local authorities around Arborstone and Kaineng, and Ostrelen was eventually captured and arrested.
While in prison, the original consciousness of the body, Kozakura, stirred. And because fighting for control was pointless, the two began to dialogue. Holding a conversation with a tyrian for the first time, Ostrelen slowly started to find the girl fascinating, and hesitantly relinquished control so that Kozakura could try to convince the guards that her possession had naturally subsided.
However, Ostrelen's tendency to have fight of flight (often fight) reactions to danger, she began to hijack Koza's body out of frustration or fear rather often. Even today, this impulsivity is something the two struggle with as they try to coexist.
They remained wards of the Empire throughout the eras of rulers, with varying levels of freedom, but got their big break during the Shiro's return. As somebody already possessed, Koza was found to be immune to the Affliction, which made her the perfect weapon against Shiro. She didn't particularly enjoy the campaign, but her and Ostrelen succeeded nonetheless, and were heralded a hero of the empire! She was given a proper title and job among the empire.
Emperor Usoku complicated things, and she had to seek refuge for a while. Kuunavang, the saltspray she'd saved, settled their debt by offering her a home out in the wild, and the three grew quite close. When Navan decided to join human society and work for the Empire, Koza and Ostrelen hesitantly followed her.
Court drama yuri ensued. Ostrelen is somewhere between their third and their platonic cat third-wheel.
Things were peaceful until Koza's brother, Tamotsu, possessed by the other twin dagger, showed up for EoD. Koza and Ostrelen both had some old beef to hash out. Both sets of siblings are still estranged in current day, but they're at least cordial during Tyrian Alliance meetings.
Personalities
Kozakura is dry and witty, and prefers to keep to herself. This, however, is mostly due isolation throughout childhood and most of her life. Once she makes a group of good friends, she lights up - A bit naive and insecure, but markedly more playful. Big fashion and takeout food enjoyer. She's not very good with her money and is struggling to keep up with technology.
Ostrelen was little more than a servant during her life in Nayos, and often lived in repressed fear. Once in Tyria, she felt emboldened to lash out, used to a dog eat dog society. She's since mellowed out, coming to appreciate Tyria, but she can still come across as a high-strung nagger with way too much snark. She's very curious and nowadays comfortable with asking questions, no matter how much they make her stick out, which has led her to take up research as a side-job. She despises authority, however, and hates that Koza is fine with being a dog of the empire. She sometimes fantasizes about tearing it all down... but that would be more trouble than its worth.
Dynamic
Unlike Arth, who has no real distinction between host and kryptis anymore, Koza and Ostrelen have maintained a division between themselves, and take turns controlling the body. Ostrelen primarily takes over for combat (meaning Koza kind of sucks on her own), but its not the only time she does so. Its not always obvious who's in control, but the keen observer can tell the difference by cadence, body language and minor physical changes. Ostrelen speaks with a faint accent, as well.
Koza's body can look more or less demonic at will, often corresponding to what's needed for combat. However, she never looks 100% human (sharp nails + teeth, tail, etc)
