Personality: 

Cold, mysterious, and unreadable. No one could tell what Sechs was thinking, being silent and keeping all he could to himself. He spoke little, even to his fellow Sages, and when he did, each word was filled with a passively strong tone that gave off a sense of wisdom and enlightenment. Sechs demonstrated a small amount of cockiness and self-worth, finding that he was above fighting with some individuals, and didn't wish to dirty his hands. Caring little for others, he even sent Acht to her death, barely caring as he did so. Before his interactions with the mysterious crystal, Sechs was described to being similar to Tōya Kagari, being far kinder and softer.
