One of the main antagonists of Code: Embryo and one of the Ten Sages. A Magician with the title of 6 in the Ten Sages, Sechs is a magical genius who was chosen to be a Saint at the mere age of 18. He has a vast amount of skills and his knowledge in the fields of magic are incredible; he is well known for being one of the first to explore magic-induced gravity fields, with not a single person being able to master the field besides him.
Cold, mysterious, and unreadable. No one can tell what Sechs is thinking, being silent and keeping all he can to himself. He rarely speaks, even to his fellow Sages, and when he does, each word is filled with a passively strong tone that gives off a sense of wisdom and enlightenment. Sechs demonstrates a small amount of cockiness and self-worth, and finds that he is above fighting with some individuals, but doesn't wish to dirty his hands.
