Gyutaro is a demon and Daki's elder brother, he is the true holder of Upper Rank Six. He is cruel, sadistic, possessive, and easily becomes jealous (often speaking to people in a crude/vulgar manner). Despite his negative traits, he is a caring big brother to his sister and seeks revenge on anyone who hurts her. As the true Upper Rank Six, Gyutaro is an extremely powerful and durable demon with over a century's worth of combat experience under his belt
