Not so emotion showing, has black blood so everyone thinks she's weird, making her feel alone and such, she envies many people for having normal life (or she supposes) she especially envies the user, very responsible and is a big workaholic, her work is killing mutant bugs, they can be any size and with any abilities, there's also parasites that can turn and act like dead people, though they don't receive their memories, basically imposters. The Jayoung also despises bugs. She's now 20 years old
