Amakusa-Style Remix of Church

 The is a secret Christian cult based in Japan. They are noted for their subtlety in practicing magic, which is carefully hidden in everyday objects and bodily gestures.

Background
This sect of Japanese Catholics were formed when Japan banned Christianity from the country and killed those that believed in it. To escape persecution, they hid Christianity behind Shinto and Buddhism symbols and with their Catholic beliefs, though in time nobody can distinguish between the different aspects of Christianity and others from the teachings of the Amakusa Catholics, resulting in it being called a 'fusion style' of Christianity by the Magic Side. Though they are a religious sect they do not have any church of worship, rather they meet up in different places outside of Academy City. They are also skilled in melee combat and group battles in addition to their magic. Though according to Tatemiya their specialty is naval warfare.

Organization
The Amakusa-Style Church is led by Substitute-Supreme Pontiff Saiji Tatemiya, after its supposedly new leader Kanzaki Kaori rejected the position in a past event. She later reinstates her position and took over as leader to lead on the attack against God's Right Seat member Acqua of the Back. Now that she is the leader, the organization become like somepart of Necessarius.

Amakusa Church's Magic
The Amakusa Church's magic have evolved from what the Roman Catholic Church used into a unique form of magic, merging it with words and things that was used in everyday life, making it almost impossible for outsiders to read their spell pattern and spell composition, even for the grimoire library Index Librorum Prohibitum. When the Agnese Forces first fought the Amakusa Catholics they see similarities in the techniques but it has been heavily influenced by Shinto and Buddism magic, which Stiyl notes the Agnese Forces have good observations to even be able to see that much.

Most members specialize in certain spells, but here are some spells shown that every member can use:
 * Steel Wires: Using steel wire to make 3-dimensional magic circles that surround their enemies or into a more direct attack like Kanzaki's "Nanasen" (Seven Flashes). Examples include in Volume 14 where Itsuwa used Nanasen against Terra of the Left, and in Volume 16 against Acqua the Amakusa Church used a 3-D magic circle made of 250 wires split between the 50 members to launch a attack on Acqua.
 * Healing Water: Enchanting water to be able to heal all external wounds and even erase battle scars. Shown in Volume 11.
 * Charms: By preparing paper charms before hand they change the charm into anything made of wood, from wooden utensils for eating, to bridges and sailing ships. The logic behind this is paper are made from wood to begin with and by using magic to reinforce this connection they can change the shape and form of paper.

Angel Fall
The Amakusas were mentioned as the group Kaori was the leader of but left due to hating her position and the pain that it brought to others. The group itself was not introduced in this arc.

La Regina del Mare Adriatico
The Amakusas go to Italy with Orsola to help her move. Later, they are told by Index that Touma and Orsola had been captured by the Roman Catholic Church. Using their instant ships, they managed to save Touma, Orsola, Lucia, and Angelene from drowning. Next, they stage a rescue mission for Agnese Sanctis, distracting the rest of the fleet while Touma, Orsola, and Index rescued Agnese.

 * “It’s said that this guy sent the female Supreme Pontiff-sama flying together with that ‘Seven Heavens Seven Swords (Shichiten Shichitou)’ with just a single punch…” (Note that the scene that gave birth to this was ommited in the manga and the anime).
 * "He saw the Supreme Pontiff’s naked body, took a strike from ‘Seven Heavens Seven Swords’ and didn’t even need a cast!".
