"Knowledge is Thee Feeder of Grief, but Thy Giver of Hope Also."
"But the Raven, sitting lonely on the placid bust, spoke only That one word, as if his soul in that one word he did outpour. Nothing farther then he uttered—not a feather then he fluttered— Till I scarcely more than muttered “Other friends have flown before— On the morrow he will leave me, as my Hopes have flown before.” Then the bird said 'Nevermore.'" - Edgar Allan Poe, The Raven
[The Raven] is just that, a raven who appears before the main character of a poem, and as the messenger of ill-omen, he comes to report the death of Lenore, a dear person to the main character. At first, the protagonist just mutters that the bird might leave, to which the raven replies, 'Nevermore'. This humors the man, and he starts to ask more, only to eventually be frantically asking about many other different things, including if his, what is later theorized to be his mother, made it to Paradise, to which the raven still replies, 'Nevermore'. The black-winged bird even replies to the question if he will be leaving, 'Nevermore'. This doesn't necessarily mean that the raven will stay for all eternity, but he will watch over the man, hinting that there is more tragedy to come.
[Appearance] : The Raven, in his humanoid/demon version of course, is dressed in shades of black or dark gray. Why he is wearing the hood, is to represent that he is a creature of death, as in he has close ties with Shinigami/Grim Reapers. One eye is gold; I figured it fit, since demons have a habit of either having gold or red eyes, at least in Kuroshitsuji/Black Butler. The red eye is a bit lighter, because even though he is a messenger of ill-omen, it isn't like he causes it. I used symbolism to say that death wasn't the whole of what he is, and by the way, that eye is blind. Other than his cloak, he wears a high-collared shirt underneath, black pants, and knee-high boots. He has a pony-tail holder.
[Personality] : Unlike most demonic entities, he had no problems when dealing with creatures, light or dark, since the Raven is technically in between the two. This demon doesn't eat souls, unless they are destined for hell anyway. He likes to speak in Old English, and may sometimes rhyme, but speaks fairly few words when speaking of death. Obviously, it is a serious matter, and should be dealt with as such. He's quite soft-spoken, and will rarely be angered; by the way, he can really turn into a raven; I guess you could figure as much. The Raven isn't one for liking sweets, but will eat some if offered, just to be polite.
