S01E01 Devil and Realist
William Twining is the orphaned son of the Twining family, one of Britain's oldest and most noble lines. When he learns his tuition has yet to be paid, he returns home to find the family...
Even after Camio reveals himself, William remains concerned only with his grades and tuition and tries to distance himself from the demons and their political war. Unfortunately, he soon finds himself roped into another problem when the Headmaster asks him to find the source of a mysterious singing voice that's been disturbing students late at night.
A brilliant, skeptical noble accidentally summons a powerful demon and is forced to choose Hell's next ruler, while demons and angels battle for his nomination.
