Arquebus Academy is one of many locations in Hekseville, and is one of the city's more well known landmarks.
Arquebus Academy is located on the outskirts of the district centre in Pleajeune. It is, as its name would imply, a high school. In Gravity Rush, a good percentage of story in Pleajeune takes place in and around the academy. While Pleajeune as a whole has a purple tint to it, Arquebus Academy has a brown tint to it.
After asking around the centre of town for Echo's whereabouts, Kat takes Newt to the school grounds to find out where she is. The school grounds serves as the arena for the boss fight against a possessed Echo.
In Gravity Rush 2, only 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 hours after hours. When out on her patrols, Raven stops by the academy to congratulate Eugie on being accepted into Arquebus.
