HOLY CRAP I updated this. Well, it's short, but it's an update. I am going to be writing fanfiction endlessly over the holidays, by the way.
Shinji and Aizen belong to Kubo Tite. If I owned them, bad yet awesome things would happen.
If he had to say (and honestly, he didn't really want to), he would say that Hirako-taicho was defined by his smile.
The man's sly smirk would twist into a lecherous leer on those quite nights when it was just the two of them. It was not an attractive smile, but he couldn't help but admire the dominance that radiated from it.
In the mornings and afternoons, it was a self-satisfied grin, eyes and teeth glinting as though he saw right through everyone.
But Aizen rarely saw his captain smile genuinely. He didn't think the man was capable of such a thing.
Then again, neither was he.
