Kyomashi was a normal high school student, until he started seeing ghosts and hollows. Because of this, people kept their distance from him, thinking he was weird. Because of this, he felt isolated, like he wasn't human. One day, a hollow attacked him, causing his latent powers to be awakened. Kyomashi developed psychic powers and caused a large amount of chaos over the entire city, and he blacked out. When he came to, he saw a man in black standing in front of him. The man in black took Kyomashi and brought him to a secret lab where he preformed countless experiments on him, turning Kyomashi into a Soul Reaper, infecting him with hollow souls, and making him battle his other 'failed' experiments. It was hell, and each experiment was one that could mean death.
Months passed and Kyomashi became stronger and more knowledgeable in how souls work and even though he was experiencing painful experiments almost everyday, he still kept his light. He didn't lose hope of getting escaping. However, there was still a part of him that told him that he'd be there forever. Kyomashi devised a plan to escape during a battle with one of the failed experiments. Kyomashi used that short string of freedom to escape the lab, causing the man in black to chase after him, and eventually, engage in battle.
When battling, The man in black told Kyomashi many things in order to throw him off guard, telling him that the chaos that Kyomashi caused with his telekinesis killed his mom, that it destroyed his school, his house, and everything he cared about. When Kyomashi asked what happened to his dad, the man in black pealed his skin off, showing that he had a face mask, as he revealed that he was Kyomashi's father, Maruta Ryuga.
Maruta said that because of Kyomashi, Sakura, Kyomashi's mother, was dead. He said that the experiments he preformed on Kyomashi were to find a way to bring Sakura back to life. He could not find her soul or body anywhere, and that he was going to send Kyomashi to the Soul Society to look for her there because he could not. Kyomashi and Maruta stopped fighting and Kyomashi said that he was sorry for what he did. Maruta told him that if anyone should be sorry, it should be himself. Kyomashi said he will go to the Rukon district to look for his mother, and then suddenly, a Senkaimon opened, and a Captian-class Soul Reaper walked out, declaring that he was going to Kill both Maruta and Kyomashi. Maruta told Kyomashi to hurry to the Soul society. Kyomashi quickly opened up a Senkaimon and jumped into it, traveling to the Soul society and ending up in the Rukon district, while Maruta stayed behind to fight the Captain.
Kyomashi asked all around town about his mother, but every time he asked, the people went silent and put on a sad face. A girl then approached Kyomashi and lead him to his mother's grave. The girl said that his mother died protecting her from a hollow, and said that she was sorry she died because of her. Kyomashi smiled and hugged the girl and then went back to the world of the living.
When Kyomashi got back, he saw no sign of his father. However, he did spot the captain sitting on a large boulder. Kyomashi didn't even ask. He already knew his father was dead. And he knew that it was his turn to fight the captain. They engaged in battle without a word and after a hundreds of blades clashing, Kyomashi emerged victorious, suffering from several injuries. Kyomashi was on the ground, almost drowning in his blood. He passed out from the lack of blood and woke up in a bed by himself. He got up and looked around, his wounds completely healed. A green and white striped hat sat on the desk near the bed. Kyomashi wondered who it belonged to and decided to wait for the person to come back. However, the person didn't. Kyomashi then decided to live there until he found the person who took care of him. He then got a job at a fast-food restaurant while still keeping an eye out for hollows and the Soul society who still want him dead for killing a captain.
