He is not officially recognized as a saint.
The youth that played the role of leader of the Shimabara Rebellion, an uprising that occurred in the early days of the Edo Period. He, who concentrated on his studies since childhood, began to perform many miracles at the frontier for a time. Having healed wounds and walked on water, he eventually began to be enthusiastically worshiped as son of God by the peasants that believed in a prohibited religion.
Before long, former-vassals of Konishi Yukinaga that had him as leader established a rebel army against the Edo Shogunate. Together with the peasants of Shimabara, who were suffering with the harsh environment of the times, they raised a large-scale insurrection. Despite taking the uprising lightly at first, the Edo Shogunate got serious due to its punitive forces being defeated and sent out Elder Matsudaira Nobutsuna as the supreme commander.
Matsudaira Nobutsuna brought on starvation tactics to the revolting army that had shut themselves in Hara Castle, and estimated the time when they were running out of food and ammunition to start his general offensive. It has been told that 37,000 people - including Amakusa Shirou Tokisada - were massacred by the shogunate forces, with the exception of a single betrayer (there are various theories about this).
Although mediocre in parameters itself, he holds the record of being summoned under the Ruler Class during the Third Holy Grail War of Fuyuki. Thanks to the function of Command Spell enforcement from Divine Ruling and a strategy of poking at weaknesses by means of True Name Fathom, he reached up to one step away of attaining the Holy Grail, but was ultimately defeated due to the death of his Master.
Amakusa Shirou's dream began from that point on.

By connecting both arms to the leylines, excessive magical energy is inserted in the magic circuits of both arms and made to rampage. A destruction-type Noble Phantasm that refines pseudo-black matter and swallows all beings on the surroundings. Because it requires an excessively vast magical energy, originally it is impossible to employ it as a Noble Phantasm. In order to completely impel it as Noble Phantasm, he must first somehow establish a magic energy supply route different from his Master.
