Amakusa Shirō Tokisada was a 17th century Japanese Catholic from the Amakusa islands who participated in the Shimabara Rebellion against daimyo Matsukura Katsuie over heavy taxation and persecution of Christians. The rebellion was suppressed, and Shirō was beheaded at the age of 17; Katsuie would subsequently be deposed by the shogun, though Christian persecution in Japan would not end until the 1870s after the Meiji Restoration.
Design
Shirō's camp banner
The banner Tokisada carries is based off of Amakusa Shirō's real-life camp banner (Japanese: 天草四郎陣中旗, romanized Amakusa Shirō Jinchūki) painted by Yamada Emosaku.[1] This banner depicts a Communion chalice and host flanked by two angels. The text reads in Portuguese (the language of the Jesuit missionaries in Japan) Lovvado seia o sãctissimo sacramento (modern spelling: Louvado seja o santíssimo sacramento), meaning "Praised be the most holy sacrament"; note that Kaneko's drawing is missing the final o in the first word that is present on the real banner.
Fully known as Amakusa Shiro Tokisada, his baptismal name was "Geronimo", though it became "Francisco" during the time of the rebellion.
He was the leader of the Kan-ei 14 (1637) rebellion of Shimabara, though it is said that the mastermind of the rebellion was someone else and that Shiro was set up as the leader. After successfully defeating the Shogunate army several times, the rebels were finally besieged at Hara Castle and killed. His head was put on public display. He lived a mere 16 years.

Trivia
According to Kazuma Kaneko, Tokisada's disembodied head functions similarly to the character Count Brocken's from the anime Mazinger Z.[2]
Due to the popularity of the 1981 film Samurai Reincarnation there was a surge of popularity in depictions of the historical Amakusa Shirō, which drove Kazuma Kaneko to make the Shin Megami Tensei: Nine design distinct to stand out from the rest.[3]
There is leftover unused data for Tokisada as a demon in Shin Megami Tensei: Nine. He is of the Fiend race and is level 75.
