Risk Storage is one of the final bosses of Darius Gaiden, being fought in Zone V. One of Belser's leader flagships stationed at Planet Darius, it is found beneath the oceans of Darius. It is shaped after a gulpfer eel.
Risk Storage initially attacks by swinging it's large tail and shooting from the tail's tip. Once the tail is destroyed, it will use it's mouth to shoot beams and release cylindric things which also shoot. Though it is destroyed, the damage it causes to the Silver Hawk proves fatal due to the water pressure, killing the pilot.
