Up to Eleven



Up to Eleven (エクストラゲージ) is a weapon that can be used by Demyx in Kingdom Hearts 358/2 Days by attaching Ultimate Gear. It can be upgraded to Up to Eleven+.

Etymology
Its name is a reference to a joke from the rock comedy/mockumentary film This Is Spinal Tap, wherein band member Nigel Tufnel explains that their amps' volume dials go up to eleven, as opposed to ten, for the sake of being able to play louder.
