So far the factions/groups are as follow: (for personal record mostly lol)
-Kaazu: Led by Hiiro, a clone and the togabito of chains. Beneath Kaazu is the Zodiac police and Nanba prisons. Their goal is to destroy all togabito.
-Zodiac Police: Organization that hunts down criminals. Currently, the warden of the male Nanba prison is looking for #610 who is the only prisoner to have ever escaped Nanba. Has become fractured.
-Ram and Sophia: They are being hunted by the Zodiac Police, Sophia's adoptive sister, Kaazu, and Shiki. They have been joined by two members of the Zodiac Police. Sophia is the togabito of Night and can awaken/ make other fall asleep.
-#610 and co: Is being hunted down by Kaazu, the Zodiac Police, and Shiki. He is an immortal togabito who can awaken powers in individuals with the aptitude for powers. He has a memory problem and is being escorted by an assassin who plans to kill him himself.
-Nanba Prison: Under the leadership of Hiiro, they function as an actual prison, the execution grounds for togabito, and as a personal cage for Jyugo. Some know the truth and others are unaware, but fractions may form as the truth is revealed.
-Uno, Rock, and Nico: For *spoiler* reasons they are maintaining a facade with Jyugo. They care about him but are hiding the truth from him.
-Enki: Decreased but he had been uncovering the truth about Nanba, and left behind evidence for the Warden and others. Kiji, the warden of female Nanba prison, and Samon are aware of some of his discoveries.
-Shiki: Led by white haired scientist(can never remember his name) who was transformed into a Togabito by #610. He is the togabito of record and can manipulate memories in various forms (such as giving memories or changing memories). He experiments a lot and is responsible for the creation/awakening of Elf, Musashi, and Jyugo. The goal of the organization is to evolve humans into togabito. They are into kidnapping and/or experimenting on people, as well as into recruiting togabito forcefully.
-Shinigami Cult: Cult that worships all kinds of death gods. Sith(?) Is a member.
-Togabitos: For various reasons they may hate or love Nanba/Kaazu/Shiki. Some are completely innocent individuals caught up in a quarrel, such as Tengu, Noriko, Musashi, etc. Some are dangerous.
These are all I can remember but man this story is great but tragic.
