Beelzebub

Beelzebub (ベルゼブブ) is a highest-ranking devil connected to the Tree of Qliphoth and has contracted with Zenon Zogratis, a member of the Spade Kingdom's Dark Triad.

Appearance
Beelzebub is a large black figure with pointy ears, two wings, four horns—two small upward-pointing horns and two larger horns that curved outward and up—and hair that reaches down the neck and splits into strands. Fur covers the devil's chest and shoulders.

Biography
During Zenon Zogratis's attack on the Golden Dawn base, Beelzebub appears looming over Yuno when Zenon draws on 55% of the devil power to overwhelm the vice-captain.

Days later, the first gate to the underworld opens, allowing Zenon to draw on 100% of his devil power. Later, Yuno's Spirit of Euros shoots an arrow through Zenon's chest, so Zenon offers to make a deal with Beelzebub: his body and soul in exchange for a devil's heart. Beelzebub agrees, effectively transforming Zenon into a devil.
