"According to legend, they were souls that were open and responsive to the suffering that went on in the world. It was because they were destined to create a new world when the old world would come to fall. Sensei was one of them as well. Perhaps he knew from the start that someone like Senzui would come along, and that the shadow he bore would come to devour the world. He probably saw all of this coming, even his own death, and maybe so he could leave behind a hope in this world to resist against the darkness, he created that school to properly nurture the ones that would nurture the new world."

The Sōzōshin (創作の神様, "God of Creation") were a tribe of Souls that predated the Original Sin of Soul Society. Among the beings that were born to the old world, they were considered a unique bunch; similar to that of the individual who would later become the Soul King. They possessed the power to pacify chaotic reishi and provide structure to its flow, enabling them to manipulate it as an extension of themselves. Utilizing their power, they could provide shelter and protection to their fellow man, while helping to build a new world from the devastation that surrounded them; hence the name they were given. However, their powers had made them sensitive to the souls of others and even the reishi around them. Their hearts were like mirrors that reflected the souls around them, for they were meant to embody the will of mankind, so as to create a new world when the darkness would be pacified. It is said that the ancestral founder of the Shiba Clan was inspired by them and sought a solution for the world in which Hollows could instead be purified rather than destroyed mercilessly, for they too possessed hearts; a notion that would later give birth to the modern Shinigami.
However, it had became too much for some Sōzōshin, who were driven mad by the thoughts and emotions that they were forced to experience, causing many to use their powers solely for themselves or to satisfy their selfish desires. This eventually led to a split among the Sōzōshin that had soon resulted in an internal conflict between the two familial factions; the Asakura Clan and the Kawahiru Clan. When the war between them was settled, following the eventual splitting of the old world and the creation of the three worlds as they exist today, the Kawahiru had obliterated the other faction, and over the ages, the history of the Sōzōshin themselves had faded into obscurity, with the existence of this lineage itself falling to nigh extinction. It was not until millennia later that a surviving member of the Kawahiru, the legendary warrior Shōyō, helped to continue the family line with the birth of his daughter, Tsuyuri Kawahiru, who eventually gave birth to Seireitou Kawahiru, Kamui Kawahiru, and later, Yukina Kawahiru. Still, no records of the Sōzōshin are considered to still exist, with few living beings even knowing of their history.
During the Warring Souls Period of Soul Society's history, and later the threat of the Quincy King Yhwach, there was a fear among those who served the Soul King that his death was a very real possibility. If he were to perish, all three worlds would fall with him, and the chaotic world of old would return once again. Because of this fear, they considered a ritual in which they could impregnate a woman with the essence of the Soul King so as to give birth to an heir that would serve as a suitable replacement should the King fall to the hands of the enemy. They required a woman who possessed a strong bloodline that could conceive such a child. At first, women from the five noble houses were considered, but eventually they settled on Tsuyuri Kawahiru; one of the last remaining members of the ancient Sōzōshin tribe. The ritual was deemed a success and a child was born from the conception — that being a child that would be named Kamui Kawahiru. However, another child was born together with Kamui; a second son born at the same time that seemingly did not inherit the Soul King's powers due to the Kitsune blood he had inherited instead from the mother. Regarded as disposable, a child never meant to be born, the boy was cast below to the Rukongai and left to suffer a pitiful death. Yet, through all odds, the boy managed to survive and eventually became known as Seireitou Kawahiru.

Soul Empathy: What made the Sōzōshin different from normal souls was their abnormally high sensitivity to other souls as well as the world around them. Among the many feats such a characteristic allowed them, they were able to enact influence over reishi in a manner that rivaled or even surpassed the Quincy that would arise in the future. It was a power meant to "connect" in the truest sense, for Sōzōshin were tasked with helping to forge a new world for their fellow man. They could connect their souls to the souls of others and even to the reishi around them, which themselves were fractured remnants of past souls drifting through dimensions. According to legend, it connected the Sōzōshin to the suffering that went on all around them, making them perceptive to both the state of the world as it was and how it would be. However, some Sōzōshin saw this as a means for control, enslaving others by controlling their souls and reigning them in with force of will. Such power over others drove many Sōzōshin mad, turning even the kindest individuals into tyrants, which warped their beliefs and led them down a path of conquest, eventually leading to the split between the Kawahiru and the Asakura. It is noted that only true-blooded Sōzōshin ever inherit the essence of Kamimusuhi, or more accurately, the power only manifests within true-bloods. Within Kamui Kawahiru, this gifted him with the "All-Sight", among other extraordinary facets, while Seireitou Kawahiru, who was born with a Kitsune heritage, did not inherit any of these latent Sōzōshin abilities.
