Church of Orsola

The Church of Orsola (オルソラ教会) is a church that was under construction in Japan somewhere near Academy City. The Roman Catholic Church named it after Orsola Aquinas for her contributions of traveling to three "pagan" countries to preach Christianity.

Appearance
The building was planned to be the largest church in Japan at around the size of a baseball stadium, holding 250 or more people even during its construction. It is composed of seven chapels, each intended to be used to carry out one of the Seven Sacraments. The size of the respective chapels varies as their construction and the funds expended on each differed depending on each chapel's individual importance and how often they are used. The two largest are the Marriage Chapel and the Fuyou Chapel, the latter being the second largest which is used for funerals. Other chapels are the Holy Order Chapel and the Confirmation Chapel, which although important religiously are smaller as they cannot make money, and the Baptism Chapel. Due to the church also being a tourist attraction the Roman Catholic Church set up a website for it that is even compatible with mobile phones.

The church is apparently small enough to be accommodated by a single talisman of the Divine Protection of Ægidius.

Orsola Aquinas Rescue Arc
After Agnese Sanctis and her forces recovered Orsola Aquinas at Parallel Sweets Park they retreated to the Church of Orsola. They placed a barrier around the partially constructed Church and gathered inside. Inside of the Marriage Chapel of the Church they gathered and they tortured Orsola until Kamijou Touma arrived. Shortly thereafter Stiyl Magnus, Index, and the Amakusa Christians also arrived and the battle between them and Agnese forces began inside the Church.



Shortly after the battle began, Touma ran out from the Marriage Chapel and eventually reached the Holy Order Chapel which is located behind the Marriage Chapel and climbed to its second level using one of the construction ladders. His pursuers then fired magic from their weapons to collapse the unstable platform he was standing on instead of risking climbing up after him. Before it completely collapsed, he managed to jump up to the roof as it tipped it slanted upward, allowing him to climb higher. He then fought several nuns on the roof while Tatemiya Saiji, Index, and Stiyl Magnus were fighting near the atrium between the Marriage Chapel and the Baptism Chapel. After the tide turns against them they along with Touma rush and lock themselves in the Fuyou Chapel.



After the nuns break into the Fuyou Chapel, Touma and the others escape and split up. Touma then goes to the Marriage Chapel to confront Agnese. After fighting for a bit Agnese seems to have the upper hand before they notice that everything in the Church was quiet. The others arrive and reveal that they were setting up runes for Stiyl with the help of the Amakusa for he could use Innocentius. With the help of the Amakusa they set up 4,300 rune cards to form a large picture turning the entire Church of Orsola into a giant magic array. Once Innocentius was summoned the battlefield located at the church became quiet with the remaining nuns not daring to attack with Innocentius there. The fighting was concluded with Touma defeating Agnese in the Marriage Chapel.

Aftermath
The still unfinished church was heavily damage during the battle. It is unknown what had happened to it afterwards as Orsola defected to the Anglican Church.
