Personality:Zack often speaks in foul language. He will occasionally swear in the situations he's in, and will not hesitate even if it is towards Rachel, despite her young age. It is also revealed that Zack never had any education of sort, as hinted in his inability to read, and when characters in the story explain things to him in long terms that makes Zack frustrated and unable to understand unless if it was explained to him in simplest terms. Because of his lack of knowledge and education, when he is put into a situation which requires using the brain to figure something out, he often forces upon Rachel to do the problem solving.
