History
When he was younger, his father was very ill, and he stole things to earn money for medications for his father. He had 100 of lashes (which of a full man could not take) trying to correct him, but he still stole. He had three tattoos on each hand showing that he was a repeat offender. He was called a demon child and even born with teeth to help this point. After stealing so much, the father hung himself hoping for his son to stop stealing for him and help give him a better life. But this didn't work he then when on a rampage fight the police and taking may beatings but even though he kept fighting. He was going to be killed but then a man named Keizou he beat up Hakuji and brought him to his dojo hoping to help him. He then met Keizo's daughter named Koyuki. She was ill just like Hakuji father, so he took care of her knowing he could endure it. Even though everyone else gave up on her Hakuji didn't and told her there would always be another year when questioned about why he wouldn't see the fireworks, and he promised to take her.

Three years then pass Hakuji was 18 and Koyuki was 16 and she could finally live normally with her illness finally gone. He father then asked Hakuji to take over the dojo and marry her daughter Koyuk because she loved Hakuji, they both agreed, and he was going to marry (even saw the fireworks together) and take over the dojo his life was finally going the right way even after his criminal childhood. He went to his home town to tell his father the good news, but when he came back, he found out another dojo posied their well and killed both Koyuki and Keizo. Hakuji was filled with rage he killed all 67 members from the other dojo with his bare hands; there were heads smashed, organs crushed, most of the bodies were mangled beyond recognition...some were missing whole body parts and more it was a hellish scene the only survivor lost her mind. He was wondering the streets covered in blood when Muzan found him. Muzan showed up because there were rumors of a demon was there, but it was Hakuji. Hakuji then tired to kill Muzan because he was in his way. Muzan then stabbed his hand through his face and told him about making 12 powerful demons and pumped Hakuji with his blood, his last words as a human were "Don't care anymore... I don't care to about anything". He then became a demon and killed to become stronger, but he didn't even know why, he said it was a horribly sad, laughable and ridiculous story.
