Midnight is a mage which belongs to the Oración Seis guild, a dark guild composed of highly powerful mages whose goal is to find a power known as Nirvana, a very destructive power that was sealed away long ago. Not much is known about Midnight currently that not even the Blue Pegasus Guild, who were monitoring the Oración Seis, have much information about him outside his name.

He thinks of Brain as his own father, but they are not related.
