Clan Description (with historical content)

Batsu no Kaisendo (Clan of the Reaping Death)

The Batsu no Kaisendo Clan is a clan specified on swordsmanship, but unlike the samurai or other swordsmanship specialized "tribes" they specialize on swordsmanship to become one with nature. This meant intense training for the first few members and founders of this clan. Their bodies eventually developed a mutation which allowed the ancestors to pass their long and strainful way of gaining this knowledge onto their descendants without having to train them for as long as they had trained, with this the clan would eventually grow.

The Abilities of the Batsu no Kaisendo are very simple.
As they developed the way of the natural sword they of course would find a way to not have to strain their bodies into the making of a sword, although this is part of the trial that needs to be passed in order to even be taught the ways (later more specific explanation), and not having to carry a sword with them at all times.
In simple language and without historical background this means that a Batsu no Kaisendo member can form a sword out of anything connected to nature.

Exceptions to that are
-Oxygen and any other gases
-Lightning/Thunder/whatever else you wanna call it
-Light
-Shadow
-Fire
-CHAKRA

The trial:
As important as the training to using this bloodline is, the origins should never be forgotten. That's what the last of the few founders of the clan said before he died and so today everyone in the clan has to forge a sword the classical way before being allowed how to use the bloodline.

Of course, the sword's appearance is influenced by what the sword is formed out of, e.g. color, if you form a sword out of earth it's very likely that it will be any color of brown; or shape in matters of lenght and broadness it depends on the amount of resources used and available, in matters of earth, this of course takes chakra equal to the size, so a huge sword that isn't even wieldable would be senseless and drain alot of chakra and thus it would only be able to use at jounin rank for example.

To clarify, this is NOT any kind of natural manipulation in the meaning of bloodline manipulation, e.g. Matoro with earth manipulation on kon's site. This ONLY allows the user to form sword out of natural resources.
