Zenji grew up in a broken household. His mum cheated on his dad when he was 7 and was bullied in school for how he looked and acted. His father wanted him to take up Taekwondo and boxing so that he could defend himself from the bullies and it stuck with him ever since, completely changing his looks and personality. Due to his trauma and how he was brought up by his father, he has now moved on to finding pleasure in bullying people.
