I know everyone more or less hates Kusaka, but that scene where Kiba up and breaks his neck gets me. While a dick, Kusaka had a sense of justice, which was taking out the bad Orphenochs. When they trounced on him in that episode, he reaches for the belt as not only a way to stop them, but a way to I think, preserve himself longer. He chose to fight, and even before his death, he chose to continue on. That was boss.
