Based on the Great Chain of Being, basically a Medieval poetry pattern which starts off with plants (or, if you want to be sarcastic, rocks) and ends with the realm of religion. Humans are on the dividing line in-between beasts and saints. Idea itself came from the professor saying "No one else, not animals, not angels, etcetera, gets to choose like we do."
Well, that, and the fact that Ryou-as-angel pictures have
always disturbed me. But this is because they make me wonder how exactly it
would feel to have wings grafted onto your back.

I have no wings,
and I am expected to be an angel.
I don't understand why they want it this way.
I am missing something
in their idea of me:
a chance of living in reality.
I am the angel, and he is the animal.
Between the two of us,
there should be a human being.
But there's not.
It's just us--the extremes of two realms
that can't make it to a comfortable middle.
Neither of us was given the right to choose;
we're just expected to play the parts.
For whatever reason, the two of us
aren't allowed to be human.
It's not right, but there's nothing to do.
He seems to revel
in his restriction of evil.
And I am the good one and must not complain.
I must not complain....
I must not complain....
