Mephisto Pheles is a middle-aged man with gelled hair, which is a mixture of red and blue. He has heterochromia; his left eye is blue, while the right is red. He also gives out a mysterious atmosphere similar to that of Ajuka Beelzebub.
Not much is known about his personality other than the fact that he believes in Liberalism, so he didn't get along with the previous Satans due to the previous Satans extremely domineering nature of ordering him around. Mephisto even admits he outright hates the original Satans. He also wasn't interested in the Rating Game, so he didn't give that many orders to Tannin, and allows him to roam freely as he pleases.
In the past, Mephisto was known as the legendary Devil that formed a pact with Johann Georg Faust. After forming a pact with Faust, he remained in the Human world even after Faust died and quickly rose to the top of the Magician organization, Grauzauberer, becoming the director for the Magician Council. At some point in time afterwards, he reincarnated Tannin as a member of his peerage as well.
Mephisto Pheles appears briefly in Volume 14, contacting the Occult Research Club through a magic circle, and handing them the documents of the Magicians that the Gremory Team could make a pact with. He also informs the Occult Research Club on the discovery of fake Phoenix Tears which act similarly to the genuine ones and tells Ravel to be careful, as there is a high probability of her being targeted.
