Raguel is an Archangel of Judaic and Islamic lore whose name means "Friend of God." He is also known as Raguil, Rasuil, Raguhel, Ragumu, Rufael, Suryan, Askrasiel, and Thelesis. Raguel is referred to as the archangel of justice, fairness and harmony. He appears in the Book of Enoch where Raguel is one of the seven archangels whose function is to take vengeance on the world of the luminaries who have transgressed God's laws.
Raguel is the main antagonist of the game, commanding the Angels and telling his servant Paku to give the power of Angels to Takaharu Ougi as a baby before the story began. Ten years later he would manipulate Takaharu and his partner Rei into attempting to destroy Makai and enslave the human world. However, Paku made a mistake in the past that would ensure Masaki Kuzuha had the power to thwart Raguel's plans. Masaki would refuse his offer to join together to rule over the human and Angel worlds once Takaharu proved useless. With all his plans foiled and no other options left, Raguel would go to Eden to resurrect the evil God Jashin.
