Sennen Hakushaku

A mysterious figure who has been operating from the shadows of human history for over 7,000 years.

He is a sorcerer and humanity's greatest enemy, constantly sowing tragedy and misfortune in a bid to bring about the end of the world, all while using tragedies—and the suffering souls of those affected by them—to manufacture malevolent weapons known as "Akuma."

He is a member of the Noah Family, holding the position of the "First Disciple"—the leader of the group—and is addressed by the other Noah as the "Earl of Millennium."
