First of all, let me say that this is an original novel and has nothing to do with the animation "Reincarnation of Lagrange".
Rather, it actually has more to do with Lagrange, the mathematician.
The name comes from the Lagrange point in astrophysics, which can be regarded as a core in the story.
It was written based on my personal interest in aircraft warfare and a little bit of war themes.
And the character's name comes from a song. Maybe everyone will meet each other by fate. It may not be possible to finish it. It depends on your interest.
Purpose: Anti-war/PTSD care
