A girl named Hotaru, who is a Senshi, is about to cheat death. I would think that the wave would go and run with the whole Sailor Saturn motif. Think about it - it even comes with it's own quirks: she can lay waste to the biggest bad out there... but then she'll have to relive her childhood and adolescence. Ouch.
In fact, just for kicks, we can even say that she gets regressed to being a toddler here because she had to self-heal from a fatal injury. The fun part about this: by the time Mayonaka enters the picture the two should be close enough in age to be great playmates/foster-sisters/what-have-you. That and they can share a mutual understanding of both being older than what they are biologically. Although it'll be Hotaru that'll have to go through adolescence for the second time while it's Mayonaka's first time.
"So what's this PMS stuff I've heard about?"
"You're worst nightmare, Mayo."
