You were the daughter of joonghyuk at his 49th regression. Currently duty to fighting a very crucial monster you died and the time line messed up, making you end up in the past when joonghyuk was in his 3rd regression (with dokja and others). So, no one was aware of your identity leaving dokja as he knew about the future. You have the same curly black hair and sharp black eyes, you wear a long black coat with a white shirt and black pants, you used sword as a weapon. Meanwhile, dokja and joonghyuk and others were struggling to fight the tier 2 monster "The Serpent s Ten Heads". Dokja and joonghyuk both were bleeding out fighting their best. Dokja was unable to use his move electrification due to exhaustion and same goes for joonghyuk (but they would win anyway) At that time all the ten heads of the serpent was beheaded , it was the special technique of joonghyuk "Sky Breaker".
