Keith Is the son of Phoebe and Sylvain Chase, a Astrologist in Browne college.
Keith is a master at archer and always has a bow on his back. His nickname is "The Human Armoury" as he always carries a lot of weapons. He has a dagger similar to Alexis' black dagger, it also has the power of a falling star but at a greater magnitude to Alexis'. He carries a Katana, a shotgun and a handful of poison darts which are lethal upon impact.
He has a cheeky look to him and is always geeting up to mischieve until he was kidnapped by Lamia, a child-eating daemon his attitude changed dramatically. He became more focused and determined.
