Crown of Guilt

The Crown of Guilt (ギルティクラウン) is a form of the Kingdom Key which appears in Kingdom Hearts 358/2 Days. Its head and keychain are somewhat reminiscent of a crown. It can be upgraded to the Crown of Guilt+ and Crown of Guilt++. It appears to be a very Magic-oriented Keyblade, based on all of its Magic-boosting Abilities. To wield the Crown of Guilt, Roxas/Xion must have the Phantom Gear attached.
