The Gale Thruster is an Enhanced Armament that was originally owned by Sky Raker. It is a jet pack that that allows the user to have the ability to fly. However, it can only be used for a limited amount of time as it has a infinite amount of energy to use. She has stated that it is the will to fly that powers her enhanced armament.
After Silver Crow lost his ability to fly, Sky Raker decided to give him, her Gale Thruster to use in his fight against Dusk Taker. Haru replied that he would give it back to her as soon as he retrieves his wings. After his second fight with Dusk Taker and regaining his wings, Haru returned with Kuroyukihime to give Fūko her enhanced armament back.
