High School DxD/Nightmare Fuel

This is generally an upbeat series, but there a few moments straight out of a horror film.


 * Ise's death in the novel was bad, but in the anime, viewers get to see him desperately turn to run, get stabbed from behind, and fall to the ground and slowly bleed to death before Rias saves him.
 * One of the worst was Juggernaut Drive. Ise goes into an insane berserker state, during which he CHEWS OFF ONE OF HIS OPPONENTS ARMS!!!. He also grows a multitude of limbs, from all over his body. And the real kicker? Ddraig has to warn Rias and the others to run away, because Ise would have killed them as well if they hadn't. The only reason this isn't High Octane is the way he was brought out of it.
 * Diodora apparently made a habit of finding devout nuns and getting them branded as heretics. At which point he would rape and enslave them, as no one else would have anything to do with them. This is what would have happened to Asia if Ise hadn't saved her first.
 * Gasper's face.
