Maria Posada OS

Maria Posada OS was a Never Released Operating System created by maybe Arsen or Heavy Pilot, it's pretty obvious that it's one of those CharacterOSs.
== Trivia ==
* GuitarraOS was made because of this existing for some reason, infact, it was made because Derek didn't want the idea taken by Heavy Pilot & to celebrate the 9th anniversary of the movie Maria Posada came from
