Jin-ah Sung

Age: 15-17 Occupation: Student Sung Jin-ah is Jin-woo's younger sister. She is a hard-working girl who usually tops her school exams and has a close relationship with her brother since they are the only siblings in their family. As she grew with only Jin-woo next to her with her father stranded in a gate and her mother ending up in a coma due to Eternal Sleep Disease, Jin-ah was always on edge whenever Jin-woo was in the hospital and wanted him to stop being a hunter.
