Ogre is a mysterious individual who plays a supporting role in the game. He claims to be a wandering salesman, and assists Aya every now and then during her quest to save her father.

Ogre is initially presented as an eccentric-yet-polite individual who manages to maintain a calm demeanor in spite of the insanity happening throughout the mansion. He's shown to be concerned about Aya's safety, and is willing to assist the young girl in her quest to rescue her father, though he prefers to do so by pointing her in the right direction rather than fully guiding her.

In reality, Ogre is a man who enjoys observing chaos unfold around him, and especially loves watching the various antics of foolish humans. While he mostly kept his distance whenever such events occurred, Ogre decided to take part in the madness happening in the Drevis Mansion to further entertain himself, though he keeps his involvement to a bare minimum, as he doesn't want to put focus on himself.

That isn't to say he's pure evil, as Ogre does hold a soft spot for kindhearted humans, thinking that the world would be boring if only lunatics ran about, as well as believing that heroes allow lunatics to really shine. In addition, his polite demeanor doesn't appear to be a facade, as he still maintains a friendly attitude even after revealing his character and his motives - or rather, the lack a motive - to Robin.

Ogre appears to have supernatural powers, specifically teleportation. It's also suggested he has the power to shapeshift as well, though this ability isn't seen in the game.
