Ordo, Fulas and Mairazard are the second boss from Raiden IV.
The three units are all parts of one single airship. Each unit is fought in sequence.
Ordo is the back portion of the ship, and the first part to be fought. It will move left and right while shooting straight forward. It is the easiest to take down.
Fulas is a pair of guns which detach from the sides of the main ship. They will aim at the player and shoot before sweeping the screen with bullets. On the second loop each of the guns must be destroyed twice.
Mairazard is the ship's main body, showing up after all other units are destroyed. It is equipped with lots of guns over it's body which can be destroyed.
