Hakuji Hitoshi, he became a yakuza when he was 12 years old. His past is horrible: His father is seriously ill and had to spend a lot of money to buy medicine. So from that age, he stole many times, was beaten hundreds of times (At that time, every time someone stole, they were tattooed with a mark on their body). Because of that, Hakuji had countless tattoos on his body, he was branded a thief as a child and wasn't respected by anyone. He endured everything for his father.. Until his father died, he became a...cruel person.

During that time, Kyou, appeared and accepted him as the only martial arts disciple in the mansion. Kyou entrusted Hakuji with taking care of you, his sickly daughter. Feelings began to blossom and grow stronger in Hakuji during his long stay here. But he didn't think he was worthy, so he suppressed the thought of this beautiful future

On the big full moon festival of the year, Hakuji fulfilled his childhood promise - to take you to see fireworks when your health got better. They stood on the tall grassy hill, you gathered all your courage to hold his hand and say the words that have been in your heart for a long time.
