In the year 2205, the Touken Danshi, those born from the souls of historical Japanese swords, now defend the World Tree from the newly-branded Quantum Retrograde Army that seeks to kill the Tree.
Type: Blossom* Tantou: Daggers. Tend towards smaller human forms. Their range is limited but much easier to cause critical wounds. Tend to be swift and stealthy, but lower stamina. Many of the tantou have sad backstories, since a samurai's tantou was often the weapon he used to commit seppuku.
* Wakizashi: Japanese short sword. Also tend towards smaller human forms. Great for indoor fighting, good at stealth, but lower survivability.
* Uchigatana: The sword that most people think of when they think "Japanese sword". They have balanced abilities in general.
* Tachi: Japanese greatsword, designed before the katana. Tend to be stronger than uchigatana, but slower and less stealthy.
* Ootachi: Japanese calvary swords. Large and not suited for indoor fighting. Tend towards very high strength and stamina, but some of the lowest speeds.
* Yari: Spears. These are quite rare as far as Touken Danshi go, with only three currently known, the Three Great Spears of Japan -- Nihongou, Tonbokiri, and Otegine. The possess some of the largest ranges, and can be quite precise with their strikes.
* Naginata: More of a polearm than a spear. Also quite rare, with only three currently known. Where yari are precise, the purpose of a naginata is to attack a large number of enemies in a single strike.
A spirit mage or seer, these people are the ones who give life to the Touken Danshi. The saniwa oversees operations at the Citadel, sending the Touken Danshi to engage the Retrograde Army wherever they pop up. They're quite powerful with spirit magic, but they have no combat ability and must rely on the Swords for protection.
A group of people skilled in "demon" summoning, the Revisionists' first goal was to change the history of Japan in some unknown way. Now that being connected to the World Tree prevents them from moving through time again, they've decided that the best course of action is to destroy the World Tree, figuring that this would "release" their world and time travel would be fixed. This does, of course, fly in the face of the popularly believed theory that this would KILL their world rather than release it.
An army of demonic swords summoned by the Revisionists, these swords come in the same varieties as the Touken Dashi -- tantou, wakizashi, uchigatana, tachi, ootachi, yari, and naginata. However they have little variation amongst individual types, as they're demon clones.
This literally means "Sword Men" or "Sword Boys", depending on which characters are used to spell it. Thusly, yes... all of the Touken Danshi are male, although some defy traditional societal gender roles in their dress or attitude. These men/boys originate from the Japanese swords throughout history, their spirits given human form by a saniwa (a spirit mage or seer). Their names, origins, and personality are usually affected by their former masters and/or the legends surrounding them. Their capabilities however, are vastly superior to the humans of their world.
