The Cruel Reality (PandoraHearts)

Blood. Weaponry. Lies. Darkness. None of this is foreign to Gilbert Nightray. He's known it all for two years now, since his master Oz Vessalius was dragged into the Abyss. Ever since then, Gilbert had realized fairy tales weren't true. And also that the world was a void of evil and lies told to protect the innocent.

Oz x Gilbert, though Oz isn't there due to this taking place during the time Oz was in the Abyss, as was mentioned before.
