Kazushige Nojima
A novella entitled "Case of Barret" was released in 2007 exclusively for the "Limited Edition Collector's Set" DVD edition of "Advent Children". Written by Kazushige Nojima as part of the "" series, it details the events between "Final Fantasy VII" and "Advent Children", examining Barret's reaction to his weapon and his belief that it made him a monster. At the conclusion of the story, Barret visits the creator of the adapter on his wrist and receives the prosthetic hand/gun combination seen in the film, reasoning that although he needs a hand, he also still needs a weapon to prevent others from having to fight. He then decides to return to Marlene.
