Apostles

The Apostles are a group of Earth's most elite assassins and warriors that have existed through multiple centuries, disbanded and reformed repeatedly as the years went on. It plays a pivotal role in the lives of Sadow Yatsumaru and Akihiro Masasaki.

Formation
It is not known when the Apostles were exactly formed or what entirely inspired their formation. Their name was originally () which was Hebrew for "Harbinger" and they acted as an early controversial arm of the Mossad, silencing targets and destroying enemies that posed the most threat to Israel.

Cysti Timeline
After being disbanded, they reformed and disbanded numerous times throughout history in different forms known as "Apostles". By the time the main story of Cysti comes around, the Apostles are infamous in several Earth governments and underworld factions with wide networks of spies and information. The Apostles, in their prime, were a Japanese-Christian themed elite assassin and mercenary clan devoted to maintaining the balance of life through death. Lead by the legendary Cain Masasaki and his wife, Ono Yatsumaru, the Apostles would kidnap or adopt many orphans produced from wars (most of which they partook in) and trained them into the world's most elite super soldiers, refining their talents and hardening their Wills before turning them into "Hell-Hunters", experimental super soldiers that Cain and Ono were originally the only ones of.

Such were the fates of John Rhades and James Kingsley, who, along with Elizabeth Ariae, were taken in during infant years after the Apostles lead to their biological parents' deaths, being raised and trained to kill. Being assigned the names "Sariel", "Azrael", and "Uriel" respectively, they each served loyally in the Apostles until discovering their true origins. Soon afterward, before they could decide on what to do, the headquarters of the Apostles in each country were simultaneously attacked and destroyed. Each attack left no survivors, apart from Sariel and Azrael who disappeared into ambiguity, assuming names respective to their mentors.
