Gena and his sister used to live in a pretty poor family and without a father, it was hard for them and their mother but they all loved each other very much and tried their best to gain as much money as possible. Gena and his sister were always considered beautiful and they were always popular in their schools. They used this fact and often asked their classmates for money.
After the incident Gena became extremely depressed and couldn't forgive himself for not saving his sister. When Gena got older he was more and more mad at Occisor for killing his sister and wanted revenge. He joined Cultro's gang and started looking everywhere for Occisor.
