Acqua of the Back

Acqua of the Back, or William Orville, is a member of God's Right Seat. His Sorcery name is Flere210, "The one who changes the reason of tears".

Appareance
He is brown haired man who usually wears blue thing which are related to the color of the symbol of God's Power.

Personality
A realist when it comes to combat, recognising that there is only allies and enemies on the battlefield and shows no mercy when it comes to a battle. Outside combat he is an honourable and intelligent person, as shown in the intermissions of vol.16, where it shows parts of his past deeds. Because of his actions outside battle, being considerate to the victims he helps he is called a 'Sage' in some circles. An example of his actions are the "England Third Princess Rescue Mission" (end of Chapter 3, Intermission 3, Volume 16), where he uses his role as a mercenary to step into any battlefield when the Knights of England are otherwise tied down by political issues and orders from the Royalty faction. His friend, The Grand Master of the Knights, was willing to give up his Family Crest and all that comes with it in order to accompany him and help save the then 14-year old 3rd princess, but was disabled by William from doing so. Saying that his own role as a mercenary means he can enter any battlefield, but he can't stop the same scenario from happening again, where one of the Royalty is discarded like a mere pawn, so looking at the long run the Grandmaster needs to keep his position as a Knight where he has access to the Royal faction and prevent something like this happening again.

Like Touma, he also is true to his ideals, though his ideals is different to Touma's. As suggested by William's crest when he was designated to be a Knight, his goal is harmony between the four cultures (English, Irish, Dutch and Scottish) and three factions (Knights, Royalty and Anglican Church) of UK so they can perform at the best of their abilities, and believes by performing outside the system he himself can do things that any one of the factions cannot do when restrained by political pressure.

In addition, also like Touma he values his friendship with others, though he won't allow that to get in the way on the battlefield. This is demonstrated when he finally defeated the Grandmaster in volume 18, saying though he have won he did not carry a blade that used to kill a old friend.

Plot
He was formerly a mercenary that operates mostly for the benefits of UK, taking jobs from the Royal faction and sometimes working with the Knights of England, 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.

The antagonist in Volume 16, that battled with Touma, Amakusa Catholic Church, and Kanzaki Kaori. Defeated by Amakusa's "Saint Destroyer" after multiple battles.

Later on he appears again but still weaken with the effects that created by Amakusa's "Saint Destroyer" his power was reduced to a ordinary Saint. He participated in the English Civil war protecting Villian from being captured and executed by Carrisa and he fight his old friend, the Captain of the Knights and finally defeated him. 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 Shiage and Takitsubou Rikou under his protection on his quest to hunt down Fiamma.

Abilities

 * Divine Mother's Mercy, although a member of God's Right Seat cannot use spells that are used by normal sorcerers, he is blessed with this condition which allows him to use spells that a normal human can use like runic magic, showed in volume 16, when fighting against the Amakusa Church and later on Kanzaki he demonstrated he can use Runic Magic similar to Stiyl's, though Acqua's runes are ones controlling water into various forms, as part of the powers from being part of God's Right Seat and aligning with Archangel Gabriel. Kanzaki notes he is just as capable as 'The Power of God', Gabriel, when it comes to manipulating water, having experience in a battle with them both. Some other spells he is capable of are vacuum cuts, avalanches, and his trademark technique as a mercenary where a layer of water is between his feet and the ground, allowing him to move in such a way it can't be predicted by opponents. After the battles against the Amakusa Church, he can no longer use the Divine Mother's Mercy spell, though it is unknown whether this is permenant.
 * Stigma, the ability to call upon God's power, so he is also endowed with super-human capabilities. 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.


 * Mercenary abilities, he have many years of battle experience accumulated from his role as a mercenary, can perform maneuvers like blocking a physical attack without needing to see it, judging the distance and direction only by the wind pressure.


 * Great Sword Ascalon, showed in the Volume 17, was acquired it from a organization which was in debt with him, its a replica of the legendary sword made by a craftsmen many centuries ago that can theoretically slay the 50-foot long 'Dragon of St. George' using only that one weapon. It is 3.5 metres long and weighs 200kg. It also possesses the following traits, though only one can be used at a time:


 * 1) Red glow - gains capability like an axe used to cut the tendons of the dragon,
 * 2) Blue glow - a slicing weapon that cuts away the dragon's fat,
 * 3) Green glow - a 'can-opener'-esque weapon used to tear off a dragon's scales
 * 4) Yellow glow - Steel wires designed to tear apart a dragon's internal organs
 * 5) Purple glow - a metal saw designed to cut away the dragon's back-bone
 * 6) Pink glow - two-pronged nails that's used to remove a dragon's teeth
 * 7) White glow - nails that forcibly removing a dragon's nerves
 * During his fight against the Grandmaster, all 7 of the above were nullified by 'Solomon's defence'. After that he removed the hilt that had a hidden blade embedded into the main blade, and can turn into a giant mace or club, and also has a hidden machanism that can shoot a hidden dart. William used this to finally bypass Solomon's defence to defeat the Grandmaster.

Trivia

 * The narrative from the volume 17 hints that William resembles St. George.
