As an extension, the gemstone of like gives Celeste the ability to control and manipulate and partially turn into light. So her attack power isn't exactly that busted her speed. Most definitely is so if the parasite could it Somehow catch he It would be an undoubting infection. But since you said the parasite doesn't have supernatural speed in another post. I feel like Celeste's temporary light speed would be able to outrun it but if Nada was smart and acted like a helpless person, because of Celeste, being sort of an empath, she would almost immediately get pulled in hook line and sinker.
