This is, well, Ike/Rai in his crow form. Ike (or Rai, which is his actual name... Ike is just an alter-ego) is an Anthro, Lycanthrope, Skin-walker, Were-person, or whatever you wanna call it. In other words, he's part of a clan that is 9/10 animal and 1/10 human. Anthros used to be almost completely human with the ability to change into animals, but as the generations went by, their human forms began to look more and more like their animal forms. The elder in Ike's village said that it's likely that one day Anthros will become completely animal, and they will lose their human attributes. They are practically animals already, for they walk on all fours at all times and they communicate in the language of the animals.
Anthros, Angels, and Sirens are known as the "Anonymi," because they are believed to be myths by the humans. They are all offended by the stories that humans made up about them, so they hate humans. The three clans live in secluded areas where the humans can't find them: the Anthros live on a small island far from the shore, the Angels live in a range of mountains that are too treacherous to climb without flying, and the Sirens (of course) live in the sea. Sirens are the most bold and the most arrogant, so they like to drown humans as revenge. The other two just stay out of the way, hoping that they will remain unnoticed.
Though Anthros are a weird clan, Ike was the weirdest of them all. He was, supposedly, born with strange markings covering his left forearm, and something happened in the past that made everyone fear him because of it. Most Anthros could only change into one animal, but Ike could change into three; a dog, a horse, and a crow. The only known way to get the power to change into more than one animal was by doing a very evil, selfish deed-- taking the soul of an animal and imprisoning it with your own. Ike did not have to do this, because he naturally had that ability, but the people believed that he had done that in his previous life, and so they shunned him. But, this isn't the end of his weirdness: he was very different from others. Ike's animal forms had two huge, silver, blue-tipped, bladelike horns on his forehead, like a unicorn but more sinister. When he changed back into his normal shape they contracted and left two little marks on his forehead that matched those on his arm. Ike's ears and tail were unnaturally long, too, and he had two long feeler-like things sprouting out of his head right above his ears (don't ask why I added those on, they were really just because I thought my pictures looked kind of empty and I wanted to add something on-- now I have to think of a reason for them!). He was very odd indeed.
