Sonic Blade
Sonic Blade (ソニックレイヴ Sonikku Reivu, lit. "Sonic Rave") is a technique introduced in Kingdom Hearts. It allows the user to execute a number of successive thrusting attacks. After the first attack, execute each successive attack by using the prompted command.
Mechanics
In Kingdom Hearts, selecting Sonic Blade from the last command box activates the first attack, and if it connects, the command box will change to Rave. Selecting Rave executes the next attack in the sequence. Rave appears five times, if all the attacks connect, and is then replaced with Blast, which executes the powerful finishing thrust. It costs 3 AP to equip and 2 MP to use. Sora is invincible throughout the entire attack.
In Kingdom Hearts: Chain of Memories, Sonic Blade is an attack sleight. Starting with the first thrust, pressing 
at the end of each thrust executes the next, for up to six additional attacks. Each thrust is naturally directed horizontally across the field, but it can be angled slightly up or down when executed. In Kingdom Hearts Re:Chain of Memories, thrusts have 360-degree freedom, and additional attacks are activated by pressing 
when prompted. The timing is stricter than in the original Chain of Memories, and pressing at the wrong time cancels the sleight. The card combination for Sonic Blade is:
