Symphonie and Discordance the Girafarig

Symphonie is a B-rank Girafarig that works as a historian and a librarian of a private collection of various unusual and rare books, transcripts and scrolls that they have adquired on their multiple travels. They have a deep interest into the arcane and psychic, which has led them into the study of diverse artifacts along with their private stash of studies into the matter that has provided them with an expanded understanding of such art, allowing them to have access to some unusual abilites, like the ability to become two separate beings from their tail, Discordance, which has a mind of their own. 
Discordance is the counterpart of Symphonie, being the dark type side of them, as well of being their tail. Although they share general trails between the two, like being gentle and courteous, as well as showing elegance, calm and charitable towards others, Discordance likes to take advantage of the situations they may be in to try and always show their mischevious side towards their counter part while not in view of others, always throwing provokes and teases towards Symphonie, although they just tend to ignore these without any regard. 
While together, their unique personalities tend to cancel each other as a counteract, which always keeps them at bay, and tends to make them both show indifference or lack on interest on situations that would distract them from their research, with the exception of when others may require assistance in some way or another. When they separate, they become purely psychic and purely dark type respectively, and are able to fuse back together by merging their tails into one. During this separated stated, Symphonie shows an increased focus while separated from their counterpart, showing an attitude of superiority while also keeping their gentleness, yet that they doesn't let it reach the point of arrogance, while Discordance lets out their mischevious and spiteful side, that they don't let affect those they care for. 
Their collection is a quite ample one that they've recovered on their travels, and they usually have it open for other that are in search of the knowledge hidden within, while keeping the most threatening artifacts and scrolls locked away from curious eyes, only for them to study and protect the knowledge and powers these posess. Although he prefers to keep these artifacts locked for nobody to use, if the situation requires it, he'll use some of the minor artifacts for the benefict of others, while keeping other permanently locked down, such as artifacts capable of providing healing to those injured, or various artifacts that allow the use of different Pokemon moves to some capacity.
