Hideki was raised in a household where his parents were workaholics, and he often spent more time alone than around any other person. He was a socially awkward child, often preferring to lock himself in his room and to play on his consoles, finding it hard to interact with other children without some degree of anxiety. The most consistent interaction he had with other people was with babysitters that changed yearly.

The first 5-6 years of his life were a vicious struggle between his mother and father; his mother had always wished for a daughter and tried to mold Hideki into that desire, while his father did everything to stop that. In the end, he succeeded, but it lasted long enough to leave a permanent mark on Hideki's sense of identity. The relationship between him and his mother was anything but loving; she chided him over small things, never offered the attention he needed, put him down, and unknown to him, his father was, unfortunately, victim to her as well. She held the finance of the family and had him under her thumb, so he was unable to leave or take Hideki away. His father genuinely loved Hideki, but he didn't have much time to spend with him, and he walked on eggshells around his wife.

This all had changed at the age of 5 when his mother became pregnant with another child and when he was six, she gave birth to a young girl bestowed with the name Hitomi, what his mother had wanted all along. The albino became next to non-existent to his mother, rather giving the young girl the attention he never got — and he grew jealous until the young girl turned her attention to her big brother and wanted to genuinely spend time with him.

There was a struggle between him and his mother over her, but his father always made sure they found time for each other. Hitomi grew to be his best friend, helping Hideki open up and become more sociable and giving him someone to lean on for a bit when he didn't feel well. She was his light and he would protect her with his life if he could.

It was during this time that he had also met Haru and Raiden Lemarchal, two twin brothers that were stopping in the Edogawa district in Tokyo with their father. They were roughly around Hideki's age, only older by almost a year. It took a while for him to warm up to them, but with coaxing from his sister and Haru they all grew to be relatively close, leaving the young albino to be ecstatic to have found people who wouldn’t ignore him or drop him due to being a hard person to befriend.

He leaned more towards the quiet twin, Raiden, due to the other having some kind of presence that Hideki didn't mind ( silences between them never really felt awkward ). Hideki's favourite thing to do was to get Raiden to smile, even though that was next to impossible — the smiles he did squeeze out made every "accidental" bump over objects and scraped knee worth it.

He lead a relatively happy life, despite his parents and the trouble he got in at school when it came to fighting; he had his sister by his side and a small friend group that was tight-knit for a good handful of years. It was at the age of 15, when his sister was 9, that everything changed.

He had lost his sister to a car accident when they were out one summer day: he had been holding on to her hand when something ahead caught her attention. Against his protests, she slipped out of his grip, running ahead through the crowds — over the noise she didn’t hear the oncoming car, soon succumbing to internal bleeding on the way to the hospital. Hideki’s mother ended up blaming him for her death while his father stayed silent, leaving the albino to gain a neurotic guilt complex that heavily weighed him down for many years. Around this time his own powers manifested when his anger and stress spiked, often blowing out lightbulbs or causing erratic patterns to appear on the screens of electronics.

Haru and Raiden also disappeared not long after, leaving him alone. The albino had never learned how to properly cope with his emotions from a young age, and often got overwhelmed by his own feelings and was in a constant emotional turmoil. His anger often lashed out towards his parents or other kids at school if they provoked him; he wouldn't waste time pouncing on someone if they insulted him and he often came home bruised and hurt, even more so than before. At moments he went out himself to seek trouble, people to fight just for the thrill of it, pain, and the violent outlet.

He had grown to have a dependency on oxycodone to drown out his emotions after he had suffered an injury and had to be on painkillers. He had contemplated ending it all by taking his own life with an overdose of them, though he always ended up backing out on any attempts or spitting out the pills. He went through a total of three attempts with the painkillers, not counting the four others across his lifetime.

Things changed when his uncle whom he had never officially met, James King, came to visit one day from a distant town and stayed over for a few days. He and Hideki got along almost immediately and the albino latched to him, not long after he left and after a few weeks of digging up information online and from his father, Hideki had decided to run away from home and to where his uncle lived, bag packed for a new life.

Though surprised, his uncle took him in and eventually became the father he never had truly had from the beginning. He finished high school in Karakura and settled into his life helping at his uncle’s cafe ( Cafe Latte ). James had also helped Hideki wean off his dependency upon oxycodone, and he tried his best to offer Hideki emotional support — and to this day Hideki is thankful for everything his uncle has done for him.
