Yeon-Ji Yang

Myeong-Ji's younger sister. Yeon-Ji detests her older sister, blaming her for a tragic accident that resulted in both of their parent's deaths. After the incident Yeon-Ji became cold and callous, ignoring her remaining family in favor of a group of delinquent students.

~!Yeon-Ji later admits that her hate for Myeong-Ji was an attempt to shift the blame onto someone else out of fear of accepting that the fault of her parent's deaths lay with her, along with the fact that Myeong-Ji wasn't there for her afterwards due to a coma induced by her Fast Forward powers. Afterwards, she makes up with Myeong-Ji and they become close siblings as they were before.!~
