Yotsuyahi was born as a human, named Seisui at birth. He and his family, which consisted of him, his older brother Kazoku, his younger brother Seihyo, his younger sister Sakuhina, and their parents Natsugumo and Akiuta and resided in a rather small-sized town whose residents were highly intelligent, enough to be prestigious scientists. Even as a child, he was fascinated with space and its nature.

One fateful afternoon, a rumor spread like wildfire that a demon had killed and eaten an entire family, as said family went to a river but did not return during the night before. Paranoid of this information, Seisui's parents became overprotective and closely monitored his and his siblings when night fell. They would now accompany them to trips to the market, even though Seisui and Kazoku, his older brother, always went by themselves as they were the oldest. The following night, Seisui's parents left to gather water from the same river, despite their children's protests. When Seisui and Kazoku awoke, the siblings noticed their parents still weren't back. They frantically searched the entire town for their parents, but to no avail. Once they were about to give up, their father, Natsugumo, ran to them desperately and relieved. He was covered in blood, with multiple scratched on his face. Seisui and his siblings were shocked at this sight, but quickly guided their father to their home.When Seihyo tended to his wounds, Seisui and Sakuhina frantically asked where their mother was. Natsugumo began to shed tears, and told them a horde of demons, albeit very weak ones, ambushed them and swiftly killed Akiuta. Kazuko and Seihyo froze in horror while Sakuhina sobbed profusely.

Around 20 years later, an unknown and mysterious illness would claim Seisui's father and younger brother, and he would leave the town to study and become an official astrophysicist, and to try and forget the everlasting suffering he withstood. As he received blood from Muzan, his intrusive thoughts win the war in his mind and he decides to consume it, fully transforming him into a Demon. Now being named Yotsuyahi, he joined the Twelve Kizuki, originally the Lower Rank Four, though throughout the centuries he became Upper Rank Three, with the original holder of the position being moved to the backup Upper Rank Three.

Yotsuyahi, previously known as Seisui, was born into a human family in a small town filled with highly intelligent scientists. From a young age, he had a deep fascination with space.

One day, a rumor spread throughout the town that a demon had killed and eaten an entire family who had gone to the river and never returned. This caused Seisui's parents to become paranoid and overly protective, closely monitoring him and his siblings at night. They even began accompanying them to the market, despite Seisui and his older brother Kazoku being capable of going alone.

On that fateful night, Seisui's parents went to gather water from the same river, despite their children's protests. When Seisui and Kazoku woke up, they realized their parents were still missing. Frantically searching the entire town, they were unable to find them. Suddenly, their father, Natsugumo, appeared, covered in blood and with scratches on his face. In shock, Seisui and his siblings guided their father home.

As Seihyo tended to their father's wounds, Seisui and Sakuhina desperately asked about their mother. Natsugumo, in tears, revealed that a horde of weak demons had attacked them, resulting in the swift death of their mother, Akiuta. Kazuko and Seihyo froze in horror, while Sakuhina sobbed uncontrollably.

Around two decades later, an unknown and mysterious illness claimed the lives of Seisui's father and younger brother. Overwhelmed by the suffering he had endured, Seisui left the town to study and become an official astrophysicist, seeking solace. However, his inner turmoil reached a breaking point when he received blood from Muzan, causing him to transform into a demon. Taking on the name Yotsuyahi, he joined the Twelve Kizuki, originally as the Lower Rank Four. Eventually, he rose to become the Upper Rank Three, resulting in the previous holder being demoted as a backup Upper Rank Three.
