Camael also known as Kamuel, Khamael, Chamuel, Camiel and Camniel, is a Judeo-Christian angel, often listed as one of the archangels. His name means "He Who Sees God." He governs beauty, joy and contentment. There are many stories of where Camael was, however, he is never mentioned in the Bible. As a result, he is not fully recognized by the Catholic Church. He is also associated with the planet Mars and is one of the ten archangels of the Tree of Life, presiding over the Sephirot Gevurah.
Camael is the real identity of Dr. Bates. Later on in the game, when you access the files of the Core of Megapolis in 2052 AD he will arrive and ask you a series of questions which will determine if you take the Light or Dark Routes. However, your alignment will not change if you are already Neutrally aligned.
If Raidou is Law Aligned, then Camael will join him in the final dungeon. If Raidou is Chaos or Neutral aligned he will fight them in the final dungeon. He will no longer watch from afar any longer and will attempt to prevent Raidou from succeeding at stopping Shinado since he is not obedient to the Law.
