Acqua of the Back

Acqua of the Back (後方のアックアKōhō no Akkua), real name William Orwell (ウィリアム＝オルウェル Wiriamu Oruweru), is a character from the Toaru Majutsu no Index series. He's a mercenary from the United Kingdom and is a Saint of terrific power and a powerful magician. He's a member of God's Right Seat and works on behalf of the Roman Orthodox Church to exterminate all who have been declared the enemies of God and unholy.

He first appears in the God's Right Seat Arc where he is a recurring antagonist being the secondary antagonist for most of the story arc and appearing in the Acqua of the Back Arc as the titular main antagonist. Similiar to that of Vento of the Front, he is betrayed by his former superior Fiamma of the Right and must stop him from acquiring Godhood. At the end of World War III with Fiamma's defeat and the dissolution of God's Right Seat, he goes back to using his real name and becomes an ally of Touma Kamijou.

Appearance
Acqua of the Back is a very tall and buff man. He has a strong muscular body with a brute-like appearance and has a strong muscular face as if it were chiseled from stone itself. He has stone cold and serious look on his face and is a mark of him going through bloody and glorious battles and not the one that boldy builders have. Acqua is unique in that he is more buff and physically stronger than the other God's Right Seat members who are all thinner than he is.

His typical attire mainly consists of a white polo shirt with blue sleeves and blue pants. He also has a large blue cross emblem across his chest and has short, combed back and spikey brown hair with brown eyes. The color blue is the most prevelant in his appearance and is based off of his alignment with the Archangel Gabriel and rules over the color blue.

Personality
Acqua of the Back is a rather unique person when it comes to his ethics and morals. He doesn't call himself a good person nor a philantrophist, he has a unique code of morals and follows them greatly. He is avery honorable man confident in his powers and the rightness of his actions. In combat, he is willing to allow his enemies to live if they surrender and follows the conditions of surrender. This is shown when Touma gave his right hand to Acqua and in return, he let Touma live. Acqua loves combat and looks for formidable opponents such as the Amakusa-Style Remix of Church and Kaori Kanzaki, a fellow Saint herself. He also hates looting and cheap tricks during battle.

While he is a member of God's Right Seat, he appears to the most calm and rational member of the organization. This is shown with his hatred of using civilians as human shields and his anger towards Terra of the Left for using such a tactic in Avignon, France during the October Riots against Academy City. Acqua of the Back is also very attacthed to his home country of Great Britain and is the reason that he never joined the Knights of England. He believes that he can protect the United Kingdom from the outside in the rest of Europe.
