Arquebus Academy is located on the outskirts of the district's centre in Pleajeune. It is, as its name would imply, a high school. While Pleajeune as a whole has a purple tint to it, Arquebus Academy has a brown tint to it. In the sequel, the background has the same hue to it as the rest of Pleajeune.
After asking around the centre of town for Echo's whereabouts, Kat takes Newt to the school grounds to find out where she is. They soon find her in the abandoned student centre tucked away at the very back of the campus. The Nevi that posses Echo runs amok around the school grounds until Kat defeats it in the middle of the campus grounds.
In Gravity Rush 2, Newt is now a teacher at the Academy, and is now married to his childhood friend, Echo. A single side mission takes place at Arquebus Academy, in which Newt calls upon Kat to investigate a group of students trespassing onto the school grounds outside of school hours. Believing to have stumbled upon a mysterious cult, Kat is forced to join in the summoning of a supposed demon named "Choe", only for Echo to suddenly appear and explain what this demon is.
