DEADBOY DETECTIVES PART 2!!!
I really love how every character was given some sort of backstory that gave them some level of depth and made them more relatable to the audience...
Charles - His father was abusive, and while he was alive, he was deeply depressed but always tried to stay cherry and tried to help others which were qualities he kept as ghost...
Crystal - For majority of the show she couldn't remember her life, and her desperately wanting to help others could be a result of this. I mean she was exploited by a demon and could've been lost forever if Edwin and Charles hadn't saved her...
Edwin - He was used as a sacrifice in what was supposed to be a prank and was wrongfully sentenced to hell and tortured for decades, his prickly personality adds up, and him wanting to help others move on and find peace makes sense...
Niko - How she's so willing to run into danger to protect her friends makes sense for someone who for most of her life, didn't have many friends and was mostly alone...
