Kazuya Herikaru

Kazuya Herikaru is a young demon who travels by himself. He is known for his great power and mastery over Hell Release, which resulted in him obtaining the alias: Demon King Kazuya.

Background
No one knows exactly where or when Kazuya was born. His foster parents claim that they found him as a baby in the middle of an ominous forest. Naturally they were not going to leave the baby there so they decided to take him in. All was normal for the first three years of Kazuya's life. Unbewnost to everyone around him, Kazuya's demon powers awakened during his third year of life. Since he was unprepared for it he was unable to keep it under control, causing him to grow violent. This sudden violent attitude of his worried his parents and they asked a lot of different doctors to help Kazuya, but none of them were successful. It got so bad that Kazuya nearly killed his one of his foster siblings during that year. This seemed to be the last straw as the family abandoned him in the small village that had been his home for his entire life and ran away to another village. As a result, Kazuya was forced to fend for himself, despite his very young age. Not wanting the same thing to happen again yet wanting another family, Kazuya dove into the world of knowledge to find out what exactly was wrong with him.

It wouldn't be until he was five that he stumbled upon a book about demonology. A book that he used to identify himself as a demon. This book taught him how to keep his demonic powers under control and how to use them in a fight through the Dark Arts. A year would pass before he believed he had enough control over his powers to be a part of another family. However, this was a futile attempt as everyone in the small village remembers what he did.

The constant cycle of begging and rejection soon caused the young Kazuya to develop a trust in only himself and money. He wouldn't do anything for anyone unless they paid him and he didn't care if they were going to die or not. Despite what many would think, this attitude of his actually got him enough money to support himself. This is mostly because he was one of the only beings in the entire village that could use a form of chakra, making him sought after even though many people hated him.

A couple of days after his seventh birthday, a boy his age who hadn't heard of Kaguya, walked up to him and asked why he was always alone. Normally, Kaguya wouldn't think that the person was mocking him, but something about this boy, whose name was Kazuhiko, seemed to naive to pull something like that. So instead of trying to scare the boy he answered truthfully. The boy responded by taking out all the money he had and giving it to Kaguya. He then said five words that would change his life forever, "I am buying your friendship." Kaguya had never experienced kindness like this before so he was speechless. He soon found himself subconscious nodding his head and taking the money.

At first Kaguya was suspicious of Kazuhiko, but he soon learned to trust him. The following three years of Kaguya's life was one of the happiest years of his life. That all ended when he was ten. This is when the village erased all of Kazuhiko's memories of Kaguya because of their growing paranoia about what Kaguya might due to Kazuhiko. Angry and fed up with how the village treated him, Kaguya decided to leave the village for good.
