Despite this he is still bound by the rules of the Roman Catholic Church and its beliefs. When the magic world learns of the existence of Touma and his powers, Fiamma convinced the Pope that Touma is a Heretic and his powers are a threat to the world, The Pope declares him a Heretic that must be eliminated.

Appearance
He's an elderly man with a white beard. He wears the typical papal regalia and bears a crosier bearing the figure of a crucified Christ on the front and the figure of the hanged Judas Iscariot on the rear.

La Regina del Mare Adriatico Arc

Matthew Reese is first introduced after the events regarding the Queen of Adriatic Sea's failure to activate and eventual destruction at the hands of Kamijou Touma. Vento ordered him to sign the document that authorizes the attack on Touma to exterminate him, and by extension an invasion into Academy City to ensure the elimination of a enemy of the Church.

Later events in the novels
When the Pope later learns that Fiamma had manipulated him all this time, Fiamma casts a powerful spell to destroy the Vatican but the Pope manages to divert the spell onto himself to save the city. After his recovery he sets out to stop Fiamma and his plans, while protecting the Vatican from civil unrest that started since World War III has erupted in Europe.

In Volume 21 he single-handedly stops the riot in Rome and takes back the leadership of the Roman Catholic Church without bloodshed from the bishops that supported Fiamma, as his holiness stopped all conflict and hostile intentions just by his presence. As of the end of Volume 21, he is in the underground library of the Vatican trying to find a way to stop Fiamma's plans. In the closing phases of the war, he cooperated with the Anglican Church and the Russian Orthodox Church to take down the Star of Bethlehem, knowing that if he did so God's Right Seat will fall and the Roman Catholic Church may never recover the strength/influence it once had at the height of its power.
