yes. Spoiler!
First time line she don't have a pover but becouse the time turned back she get the pover of hope. Acording the spoilers i read once she healed her brother, but in the pre time line she killed by the demon who controlled the og fl because lily can kill that demon. So basically she have a multifuncional power ლ(´ڡ`ლ) if you interested a normal description i recommend you look up in novelupdatespoilers.
But it would make sense if her powers have something to do with time considering she went back after her death. Also makes sense why the symptoms are so punishing. Time isn't something you should be able to manipulate. Makes you closer to being a god with an ability to change things if used right.
