Ao no Exorcist

In which secrets and lies revolve around the family. One for protection, the other for ignorance and perhaps a bit of a vendetta.

Rin Okumura is not ignorant of the world revolving around him. He ignores the secret meetings of his brother and adoptive father, of whispers between the clergymen, and of the things which cannot be seen. He pushes the hurt of being left out and plasters smiles and fists to the world. And when he has a secret, it's not like it's the first he has kept. No one asks, and no one would believe him.

He is Rin Okumura, elder twin brother to Yukio, and he is also the apprentice of a reluctant Angel.

Arthur Auguste Angel was never inclined to take on a student, even if he was the best. He didn't want to teach them, requiring patience and understanding, none of which he had any desire to waste on. His goal is Paladin, having an apprentice was a baggage he did not want. Until he was given an ultimatum: no apprentice, no paladin. The council wanted him to pass his skills onto newer generations, like the current Paladin, but the exwires he had come across did not meet to his standards. He did not want a kiss-ass, someone who would report to the council without hesitation, who was all talk and no action. He didn't choose an apprentice, he'd get the seat through skill and stubborn determination.

Apprentice? What a load of bull.
