Dissonance (ディッソナンス, Dissonansu) is a Ghost ÄRM in MÄR Heaven: Oblivion of Clavier. According to Kapel, it is a Guardian ÄRM infused with the magical power of ghosts, thus changing its ÄRM classification.
Etymology and Origin
The root of "dissonant" is the Latin verb sonare. Sonare means "to sound, is related to the Latin noun sonus (meaning "sound"), and is an ancestor of the English word sound. "Dissonant" includes the negative prefix dis-. What is "dissonant," therefore, sounds inharmonic, conflicting, or clashing. Thus, "dissonance" refers to a lack of harmony among music notes.
History
MÄR Heaven: Oblivion of Clavier
Team MÄR exits the X-Ray Cave at the top of the mountain and find the Ghost Chess standing between them and Fide Arena. Kapel Meister tells Ginta that he was waiting for them, and admits gratitude for if not for the competition between their two groups he might've not found this place. Kapel insists that they give up on the Misty Castle, but Ginta and Nanashi both state that they won't back down until they've saved Alviss. Disappointed with the response, Kapel turns to Flat A who instinctively knew what to do. She then activated her Ghost ÄRM, Dissonance, to form a barrier around MÄR. Despite his teammates being unable to penetrate the barrier, Alviss walks right through it, much to Kapel's surprise. Alviss tells him that for such a smart man, he makes some pretty basic mistakes, for the Ghost ÄRM, Rondo of Time, attached to Alviss's chest rendered him immune to the effects of Dissonance.
However, with the painful symptoms of Alviss's Zombie Tattoo intensified by the Rondo of Time resurging, his teammates realize the only way for him to stand a chance against the Ghost Chess is for him to use the evil ÄRM, Evil Shield. Since Evil Shield is an anti-Ghost ÄRM, they successfully toss it to him through the barrier. With Evil Shield, Alviss is able to make quick work of the Ghost Chess, causing them to retreat, and he proceeds to destroy the barrier of Dissonance.
