A bit about Bahamut-Class City Ship "Musashi"
The ship consists of 8 sections:
Asakusa [empty] Shinagawa
Murayama Musashino Tama
Aoume Okutama Takao
with each sections being controlled by the automatons of the same name (see chart).
Musashi is practically the captain of the automatons and the name of the ship itself.
Musashi Ariadust Academy is located in the central section "Okutama".
Blue Thunder cafe (ph01s' workplace) is located in "Tama" section.
For ep 1 where the teacher kicks the Ogre's ass is located in "Shinagawa" section.
As you can see, each sections represent the prefecture of Japan so that if there's any need to reconstruct history in specific prefecture, City Ship Musashi comes into play.
City Ship Musashi can only move within other country's borderline hence the title of the novel 境界線上 (Kyoukaisen-jou = Above the boundaryline)
Not 協会戦場 (Kyoukai Senjou = Association Battleground) which majority of english speaker commonly believes
