How do you defeat Demyx in kingdom heart 2

In the beginning when you have to beat the 50 water clones use thetriangle button as much as possible. In fact just keep hitting the X button and the triangle button really fast. After you beat the clones, attack Demyx, but get out of the way when he starts riding the waves of water to hit you. Just run around a while. When he starts shooting the balls of water at you run around. When you hear him say WATER get away from where you were just standing because these balls of water will rain down on you. Once he stops hitting you with water go and attack him again. When you see him walking around in this weird way and he's not shooting water at you go over to him because maybe you can use the reaction command show stealer. If your by Demyx and you see you can use the triangle button use it, but keep a close eye on the screen because i believe you have to press it twice to successfully hit Demyx. During the battle he will have you battle water clones two more times, this time instead of 50 water clones you have to beat ten, but you have to beat them in ten seconds. Just keep hitting the x and triangle button. Near the end of the battle when Demyx starts shooting these walls of water at you get away from Demyx. Hope this helps!!
