The story of ~Elsa~ can be split into three acts.ġ. ~Elsa~ begins one year before the events of Front Mission 4 in November 2095, and ends several months after the video game in May 2097. Additionally, plot linkages to other Front Mission entries, namely Front Mission First, are more pronounced. There are numerous story elements, such as Elsa's mental trauma over killing others, that would appear new to those who only played the English Front Mission 4 as a result.

The novels revolve around the original Front Mission 4 story, as opposed to the English localization (which was censored and toned down). However, they do not exclusively focus on Elsa the story occasionally shifts focus to other characters, such as Darril Traubel, seen in Front Mission 4. As the subtitle implies, the novels revolve around the viewpoints of Front Mission 4 protagonist, Elsa Eliane. Although the novels are partial adaptations of the game, they are mostly comprised of new story content.

Released as part of the Front Mission Project line, the ~Elsa~ novels are expanded universe supplements to Front Mission 4.

Front Mission 4 ~Elsa~ is a series of novels which were released on September 24, 2004.
