Kyonyuu Fantasy Gaiden/Nightmare Fuel

The first game and anime adaptation had maybe one or two moments of this, but Gaiden takes it Up To Eleven at some parts.
 * For starters, there's a ghoul that gets unleashed on the people of Boan. Said ghoul causes people to succumb to despair and commit suicide.
 * There's also incidents with familiars summoned to pose as a succubus and Shamsiel herself. During said incidents, they kill a considerable number of people and the blame gets put on Shamsiel.
 * Saint Reaper. Badass? Sure, but he's VERY scary to the people of the story. He makes a room of berserk ghouls crap their pants. And rightly so. He's basically the incarnation of death/judgement. He can devour souls and transport them to the underworld/afterlife. In fact, every time he appears he does just that: He consumes the berserk ghouls' souls (including the impostor Shamsiel). He takes the soul of Cardinal Nigolinov on the grounds that it was deemed wicked. In fact, the very first time we see him, a young Cardinal had attempted to open the box as a test for his own worth as a follower of God, but Reaper deemed him as impure and killed him too!
