"One of the very few Transients who can actually claim to call Gehenna—where sinners from many other worlds are banished—his home. His existence is that of a demon of pure shadow, who by all rights should have remained nothing more than a shadow. Though he looks suspiciously like a certain someone, he is an entirely separate individual with the likeness being purely coincidental. Works as a secretarial aide to the Shadow Cabinet in Tokyo, though he fittingly fulfills this role largely from those selfsame shadows, rarely taking center stage himself. Faithfully serves those to whom he's contracted, and delights in nothing more than slowly corrupting them. The wording of his contract does fetter him for as long as there may be light, however, which is why he loves mirrors so: they can reflect the light, and it's through them that this demon manifests. He thinks of himself as the perfect steward, perpetually yet subtly corrupting his masters without ever shirking his duties, and he consequently finds stewards who expect their masters to have a sense of autonomy and independence to be extremely distasteful. His favorite type of people to deal with are those who are poised to fall into the depths of depravity but are holding on at the very edge; he can't resist trying to tickle and prod them until they let go."

"Mephistopheles, also known as He Who Abhors the Light, bears two Sacred Artifacts. One is a Mirror that reflects light, while the other is a Contract that can bind the souls of others with its language. Souls are, after all, little more than data, and data is, at its core, merely a form of light. Mephistopheles has had two masters in the past: one was the ruler at the very summit of Gehenna's order, whose position Mephistopheles himself is authorized to fully represent as agent; the other is the human who summoned him to Tokyo, and as a demon, Mephistopheles wishes for nothing more than to finally drag down this only human specimen who's ever escaped Gehenna with an uncorrupted soul. Both of these masters can be found in one form or another here in Tokyo, though Tokyo's System is such that only one summoner per Transient is permitted, creating something of a loophole situation. And it's through this loophole that two Mephistopheles figures are allowed to exist within the city, which likewise gives him the opportunity to forge new bonds with his former demon acquaintances from Gehenna."
He is noted to be a demon that collects the souls of the damned and ferries them back to hell. He is a worker for Lucifer and is the representative of the Devil when appearing on Earth.
He seems to appear wearing a covering for his eyes as his name in Greek means "not-light-loving", which is an antithesis to Lucifer who's name means "light-bearer".
Similar to this is Lucifuge's name meaning "light-fleer".
Mephistopheles bears a striking resemblance to Lil' Salomon albeit larger.
Mephistopheles' left horn is lacking the ring Lil' Salomon has on his, instead infernal fire can be seen with the ring's outline devoid of flame.
