Shōten

The is a formless blade crafted during one of the first conflicts between the Shinju and Amatsu-Mikaboshi, as a way to give humanity a fighting chance for their future. It earned the unique name,, due to it only allowing those with a pure heart to wield it.

History
When the first civilization of humans were endlessly being caught in the crossfire of a war between the Shinju and Amatsu-Mikaboshi, a blade was forged to defend them, created by the sacrifice of a young warrior who allowed a shaman to use his soul as a part of the blade, along with remnants of Amatsu-Mikaboshi's naginata, shattered in battle against it's rival. The pure soul from the young warrior who wished only to protect his friends and family bonded with the hopes of humanity and altered the metals from the naginata, creating a catalyst. This catalyst has a very unique ability, the ability to connect it's wielder with the energy reservoir used in the creation of future life. The blade while having no consciousness seems to have the ability to choose who wields it, only those with a pure heart and a wish to protect humanity from evil are able to grasp it and use it's abilities.

Appearance
The blade when crafted looked like an ordinary Katana, causing many to believe they had failed. It was only when an older warrior who had lost an arm protecting the humans picked up the blade that it changed. Much like the man who wielded it, the blade became older and a piece of energy became focused around the tip of the sword, causing it to smoulder. When held by Izayoi the blade becomes more western in appearance, continually glowing golden with an intricate handle.

Abilities
Shōten can only be wielded by those who are pure of heart with a burning desire to protect humanity from wickedness. The blade never dulls and is sharp enough to cleave through tree trunks with ease. Being a sword blessed by divine power thanks to the noble sacrifice used to create it, therefore the blade cannot be destroyed by any normal means. The same divine power grants some protection to it's wielder against attacks that are filled with malice, creating a personal barrier to help defend against the attacks. While strong the barrier is not perfect and can be broken with enough force, the amount of force required depends on the user's mastery over the blade.

The greatest ability of the blade is that it is a catalyst which connects it's wielder with the energy of life which has yet to exist. This energy grants numerous uses and abilities; the user of the blade can enhance themselves to increase their speed, strength, and durability. The energy can also be used to increase the cutting power of the blade and can even be weaponized in the form of energy slashes and waves. These energy waves vary in power and intensity depending on the user's will.
