Rono (ロノ) is the second boss from Super Aleste.
Rono appears as a gigantic space platform. The entire stage is dedicated to fighting it, with the boss moving in the background while the player takes on its many turrets. The actual boss fight begins when the player reaches the center.
It has nine large turrets and two small ones; the central turret shoots missiles, the four turrets on the corners shoot bullets in four directions, the turret above the central one open up to release floating mines while the one below the central one shoots at the player. The main targets are the two turrets to the left and right of the central one, these shoot a spinning ring at the player.
