Honestly, though, I can see this being an awesome idea without there being a romance that is bound to happen or if she went more on a power trip herself while becoming OP. Hell, I can see this being a more serious story about someone living through multiple lives with a different face as they start getting depressed or start losing themselves. Tell maybe they find their calling or even someone they care for. Like if they found a baby elf girl, Raised her, Died and met her again in the next life. The Elf can be replaced with something like a dragon girl also. Maybe it'll be something like a romance in development for the longest amount of time or a mother-daughter type of relationship. Hell, The MC doesn't even need to find a baby but can have her own kid.
