Mayonaka

Mayonaka (真夜中; Literally meaning "Midnight") is an organization created by Kenpachi Hyūga to bring back the Ideals of Ninshū. The organization eventually became known as the Revolutionary Priests (革命プリースト, Kakumei purīsuto) due to the fact people began to believe in this religion and those who did not, would suffer a fate no person during this era wants to face.

Summary

After a couple of years the group began to expand. Tens, of Hundreds, of Thousands of shinobi began to join Mayonaka. Some say not all who joined respect their ideals but fear their power. The organization was eventually divided into groups. The highest ranked group, are the High Priest. The group consists of 12 members three of which are Kenpachi's "pupils". Each one of these 12 members possess the ability to negates someones ability to use chakra. This division is responsible for "purifying" the shinobi who do no use chakra to connect. The next group are the Kohen which is a group of highly intellectual people. This division is responsible for encouraging others to join Mayonaka and teaching them the Ninshū ideals.
