Xie Yue, the boss of the Dark Moon Gang, came to "Yingli" University to study in order to find the missing "Star and Moon Necklace". It was a token she gave to a savior when she was being hunted. [She was only 14 years old at the time, because her father had offended the boss, and he wanted to kill her whole family, but a 15-year-old boy happened to save her. After she woke up, he gave her the necklace, and she was never seen again.}
