Albion

Albion (アルビオン Arubion) also known as the Vanishing Dragon. The White Emperor Dragon and one of the two Heavenly Dragon considered a hatred being for its great power by the three factions (Angel, Fallen Angel, Devil) that has a power to kill both God and Satan.

In the past, Albion fought against it's arch-rival the Welsh Dragon, Ddraig, which was interfered by the Angel and Devils, in anger, both dragons attack both side which lead to their bodies being destroy and their soul moved to two separate Sacred Gears, with Albion moved to the White Dragon Emperor's Gauntlet. The White Emperor Dragon Gauntlet is currently owned by Vali Lucifer a half devil/half human.

Like Ddraig, Albion has been brought to tears on many occasions due to Issei's lecherous ways and people calling Issei and Ddraig the "Oppai dragon" which resulted in Albion feeling depress on the fact that they are his rival. This is became even worse after Odin who wanted to know Vali's interest in woman and called them the "Butt Dragon Emperor"
