Acqua of the Back

His Sorcery name is Flere210, "The one who changes the reason of tears". Real name is William Orville. Blessed with the nature of "God's Power" and aligns with the Archangel Gabriel. He was formerly a mercenary for the Anglican Church but later changed his religion and joined God's Right Seat. He's also the only one who does not ignore the opinions of the Pope.

He participated in the English Civil war protecting Villian from being captured and executed by Carrisa. After the civil war in England he heads to Russia in order to stop Fiamma.

As of volume 20 he is currently in Russia, and has taken both Hamazura and Rikou under his protection on his quest to hunt down Fiamma.

Abilities
Although he cannot use spells that are used by normal sorcerers, he is blessed with the spell "Divine Mother's Mercy", which nullifies the liabilities of certain special spells so that he could perform powerful spells under unfit conditions. He also has the capacity of a Saint, so he is also endowed with super-human capabilities. On top of that, "Divine Mother's Mercy" nullifies the Limiter of the body so that he could use 100% of said capabilities as a saint. He also fought against Kaori Kanzaki -- who also has the capacity of a Saint -- and displayed a great gap between their power.
