I'm not so sure, ye know. I mean - true, she has lived those eighty years,
but most of what happened in them has been undone. She's going to have been
tugged back to her sixteen-year-old world, along with a teenager's life,
worries, and problems. 

Yes, tugged back into a sixteen year-old world with the wisdom and
perspective of an adult thrust into that position.  It should be remembered
that Akane will go through most of her life haunted by memories that will
idealize her teen years as the best of her life.  I intend to mold her into a
nostaligic with regrets that will lead to a lifetime's worth of contemplation
on how she should've dealt with life at sixteen.
