Makai Order

Makai Order is an ancient benevolent order featured in GARO Franchise dedicated to protecting normal humans from the Horrors, demonic beings that manifest themselves through darkness within hearts of humanity and serves as primary antagonists.

Among groups within Makai Order, 2 of them are serves as primary fighting forces, which are:
 * Makai Knights: Knights with wolf-themed mystical armor that bestowed them immense powers to fight Horrors and dispatched mainly to exterminate Horrors. Most of the time, each of them is assigned a district to watch over.
 * Makai Priests: Magicians of Makai Order whom job is to support the knights, mainly as their armorers, supports or as their sidekicks, but there are also those operating on their own.

Watchdogs
Priests of the Watchdogs (番犬所 Bankenjo) are the middle-persons behind the works of the war between Makai and Horror. It is they who usually detect Horror activities and inform the Makai Knight of their missions. The Makai Knights are usually informed by a letter called "Orders Document" that is mailed to them. Watchdogs have no real control over Makai Knights, but they have been involved in directing the actions of the Makai for centuries and thus, have certain extent of powers over the Knights nonetheless. They help purify the Knights' weapons, refuel their Madō Fire Lighters, and send the spirits of the defeated Horrors (in the form of small daggers) back to their realm. Whenever they collect up to a dozen blades they will send the blades back into the demon realm. There are many Watchdogs existing and directing the Makai's will in different districts around Japan, and at least one is known to have originally been human. That very human splintered her form and addressed Garo as three cherubim-like girls who, though having the appearance of young teenagers, are technically centuries old. In general however, little is known about their origins.

By the time of Garo: Yami o Terasu Mono, Watchdogs have ceased to be and the traditional duties of a Watchdog falls onto the shoulders of a Makai Priest or Priestess taking charge of a designated area. Unlike Watchdogs however, these Priests and Priestesses do not hold any form of powers over their Knights, and such relationships are built solely on willing cooperation and mutual trust between both parties.

Senate
The Senate (元老院 Genrōin) is the supervising organization of the Watchdogs at the top of the Makai Order's hierarchy of command, where only exceptional Knights and Priests serve directly under it. It has a library housing ancient texts and it is where Makai Knights and Priests alike go for information. Prior to Messiah's awakening, the Senate does not interfere much with Horror hunting affairs, and even now, it only dispatch orders after detecting threats implying major catastrophe. As an organization of higher rank, the Senate can assign tasks to any Knight regardless of jurisdiction, and orders from the Senate supersedes that of the Watchdogs'.
