Having been raised by an aggressive skulltitan lusus, he was forced to get horrible physical tolls and fend for himself from a young age. He is also prone to overestimating his abilities. He tries to present a façade of being capable and tough, but has a tendency to freeze whenever it comes to making riskier decisions. His gentler, more nurturing side is on display whenever he interacts with people he cares about.
