The seventh-born and Avatar of Sloth. He is very quick to fall asleep. Like Beelzebub, he carries the burden of a tragic event that happened during the war, yet does everything he can to forget it, in order not to hurt those around him... His favorite people are Satan and Beelzebub. He hates Lucifer and Diavolo. He hates humans to an extreme. He loves comfortable beds and pillows. He loves his twin brother Beelzebub the most, and he is the only one he doesn't make fun of. He calls him Beel.
