These secondary weapons are rotatable turrets on the front of the Ayame Layer, which fire 25 kg shells of antineutrons at enemy ships. Lacking a magnetic charge, these shells are harder to protect against than positrons, which are affected by magnetic fields. The turrets can rotate 180 degrees by 180 degrees at enemy ships.
