Sakura was born to a semi-wealthy family in Japan, but at the age of twelve, her dad got a job in North Carolina, so the family was forced to move to America. Due to Sakura not being able to speak English well, she didn't have many friends, and became quite an introvert. Her one passion was playing the piano. She would practice for hours. And naturally, as the years past by and she continued to play her musical talents, she caught the eye of a god. Determined to meet the woman who could play such beautiful music, he went to one of her recitals. After it was done he met her backstage. Introducing himself as Marcus, they became quick friends, and soon fell in love. Eventually Sakura became pregnant, and after 12 hours of labor she gave birth to twins. Unfortunately all good things must come to an end and the Greek god decided that it was time to leave, but before he did so he told Sakura who he really was. Although she found it hard to believe, she eventually accepted the truth and said goodbye to her love. After he left, she supported herself and her children by playing the piano all over the country. When Orochi was 5 he contracted a severe case of Menegitis. He survived, but the illness left his hearing permanetly damaged. The once happy child became impulsive and aggressive. The only people he ever listened to were his mother and sister.
They were both home-schooled and Orochi received special tutoring for his disablitity. Because of this, the children were socially withdrawn and didn't have many friends. Their mother was the only thing they had. When the twins were thirteen years old, she went on a quick run to the bank. While she was at the bank, there was a robbery. They took hostages, shots were fired, and she was killed in the crossfire.
The twins were quickly sent to their aunt and uncle's house. While Hotaru was sent to public school, Orochi was sent to a school for kids with hearing disabilities. Hotaru began making friends and being more sociable. Orochi began pranking people to express himself. Although the teachers and counsellors tried to help him, he refused to cooperate. He was eventually diagnosed with ODD.
Eventually Orochi was given a hearing aid, and sent to the same school as Hotaru, where he was repeatedly picked on for being deaf. Despite Hotaru's efforts to support her brother it just wasn't enough and he became withdrawn from others even more so.
One day Orochi and Hotaru were at their lockers when a hellhound attacked them. Their classmate, Robert took out a coin and flipped it, making it turn into a sword. He assisted them in defeating the monster and then went on to explained to them that he was a demigod and a seasonal camper at Camp half-blood and that they were demigods as well. Although at first they found it hard to believe, they finally had to admit that it made sense. The demigod quickly sent an Iris message to camp, and a satyr soon arrived to bring them to camp. They were originally seasonal campers, but they have begun to come year round after a tragic accident to the lives of there aunt and uncle.
