I just saw the first four eps of Ruronin Kenshin, a chunk of the Tenchi
TV series, and Highlander recently and came up with this...
What if Kenshin (or Yahiko or Kaworu) were immortal (a la Highlander)?
And what if Yoshio was once a student of Kaworu (or Kaworu's
father--yeah I know that would make it part of the OAV continuity
but...)  Actually the whole Tenchi thing could be dropped and just have
one (or more) of the Kenshin characters as immortals.  How would Kenshin
have dealt with Kaworu's death while he stayed young?  How would Kaworu
deal with having to kill to survive?  This would proabably end up being
pretty dark.
Anyone want to take it?
