Hisaka Tsukada

Hisaka Tsukada (つかさ永日, Tsukada Hisaka) is a vagrant soul having supposedly wandered throughout the Rukongai for as long as its recorded history. Her reputation is one defined by fables and rumors of her charitable kindness and ominous presence alike, a woman of miracles ever stalked by a calamity to act in her wake. With numerous records existing of many women by Hisaka's name who have mysteriously disappeared, no historian can say for certain if her story is that of a single entity or of many women throughout history who were somehow misconstrued as such. Such is a mystery even to Hisaka herself, having forgotten all but her own name celebrated by her many acquaintances and colleagues throughout her quiet and simplistic life. But that all assumes she is indeed the real Hisaka.

Hisaka, having always possessed a profound spiritual power as far as scholars could say, was widely sought after by the Gotei 13 on numerous occasions throughout history. It was her very power that would one day drive her to a life of seclusion where the general populace would be safe from its ravages. It is only now that the Gotei 13 has been left in disrepair following the Quincy Blood War that the woman of miracles has finally decided to lend the organization her aid as a full-fledged Shinigami. She was quickly granted captaincy of the Fourth Division, serving the entire organization as both a counselor and one of its greatest medics. Although plagued with amnesia, Hisaka has little concern of her own identity, instead aiming merely to assist the organization to the best of her abilities, just as she had always done for the troubled individuals she encountered throughout her travels.

History
No records exist of Hisaka's birth. According to the many tales weaved in her honor, Hisaka was born within a modest family in a largely uneventful locate of the Rukongai. Hisaka's innate spiritual power allowed her to quickly stand out within her small community. Upon discovering her natural healing affinity and acquiring a profound wisdom at some point in her adolescence, Hisaka began a votive journey with an aim to spread the wonders of her knowledge and sorcery beyond her homeland, taking her parents along with her.

Mending illness, reviving the dead and even decreeing reincarnation itself with but the simplest of gestures, Hisaka became widely renowned for her complete dominance over both life and death. And yet no matter where Hisaka journeyed, no matter how many inexplicable miracles she conveyed with her power, death loomed ever closely alongside her. She found that with all the powers she possessed, the people around her would soon be plagued by an illness even she could not cure, their very souls rendered unto nonexistence. To her shock, her parents, too, would soon suffer a similar end. Nevertheless, Hisaka remained fervent in her practice of the healing arts despite her belief her own powers were somehow responsible for the plague closely following her appearances, blessing those fortunate enough to encounter her but never lingering for so long as to devastation upon entire civilizations. She became a wanderer, fading in and out of history with recounts of her miracles spreading all throughout Soul Society.

But as far back as Hisaka herself can remember, she committed herself to a mostly solitary life, sharing her true nature with only close friends and ill-fated acquaintances. Throughout her sparse travels she would encounter many individuals who would become famous in their own right, including Glacies Fidus, a Venator Scientiae having taken in interest in the legend of Hisaka. Their encounter ended with Hisaka successfully fending off the canine with little else than her own Reiatsu, denying him a chance to acquire her knowledge; although Hisaka has all but forgotten this event that occurred many centuries ago.

Hisaka's participation in the Quincy Blood War only went as far as to slay any Quincy invading her homeland, but that was nevertheless enough for the Gotei 13 to be made aware of her reemergence. Following the aftermath of the war, Hisaka was approached by a lone officer and offered a chance to aid the organization that now existed as a shadow of its former self. Elated that she would be surrounded with relatable individuals for someone of her standing, Hisaka promptly accepted the invitation. Her training was brief, requiring only a fundamental teaching of the Zankensoki before Hisaka had become as adept as a Captain. Upon being presented with an Asauchi, Hisaka sealed her true power within the blade until less than a tenth of it remained constantly released, greatly diluting her otherwise chaotic spiritual power and allowing her to assist the organization without too much worry of unintentionally killing her allies. She was deemed more than worthy of leading the Fourth Division before she had even acquired her Bankai.
