You’ll have to complete a lengthy side quest to get the Manifest Illusion keyboard in Kingdom Hearts 2. This side quest is started after you beat the game once and return to Twilight Town. You’ll know you can start the quest when you see a small cutscene involving Hayner, Pence, and Olette. After the cutscene, speak to Hayner, and he’ll tell you about a mysterious man hanging around Twilight Town causing trouble. This man is Axel in disguise, and he wants you to retrieve a lost Duchesse from him.
What is Manifest Illusion?
Manifest Illusion is an ability that allows the user to create an illusory duplicate of themselves. This duplicate is completely under the user’s control and can be used to attack or defend as they see fit. The ability is unique to the Kingdom Hearts series and has appeared in several forms throughout the games.
In Kingdom Hearts II, Manifest Illusion is a technique Roxas can use during his battle with Riku in Twilight Town. To perform Manifest Illusion, Roxas must first unlock the ability by defeating 2000 Heartless. Once the ability has been unlocked, Roxas can use it by pressing the / button while he is attacking. Roxas will then create an illusory duplicate of himself that will attack alongside him for a brief period.
Manifest Illusion is also a Sleight that Sora can use in Kingdom Hearts 3D: Dream Drop Distance. To use Manifest Illusion, Sora must first obtain the Illusory Crystal Keyblade from Traverse Town. Once Sora has obtained the keyboard, he can use Manifest Illusion by pressing the / button while attacking. Sora will then create an illusory duplicate of himself that will attack alongside him for a brief period.
