History
Not much is known about Adiel besides that he served in the Vandenreich as "Stern Ritter B" as Yhwach's right-hand man and the favorite to become the next King of the Quincy. He faced Raian Getsueikirite, the Captain of the Tenth Division within the Gotei 13 at that time, eventually falling to his death at the hands of the skilled Shinigami.
