Hiryu Kai (飛竜改) is the fourth boss from Robo Aleste.


Hiryu Kai is an improved version of Tetsu's Hiryu, given stronger plating and new weapons. This boss attacks by either shooting a multiple energy blast or by dashing forward, after which it shoots various bullets from its back. During the fight it will be constantly aided by two options rotating around it which continuously shoot at the player, forcing it to be on the move at all times.
