It is very long, with a red sheath and hilt wrap. It has no cross-guard, and the sheath typically has a tattered cloth spiraling down it. In the past it was used to entrap all the power of evil Buddhist ceremonies. Reiki has the ability to enable people with powers to use their powers more freely and enhance them. Reiki is vastly influenced by the nature of the wielder, its powers can vary from making it rain to causing the wielder to go on killing sprees.
The blade was created by Iyo Natsume’s mother who was granted the first after her night with Susanoo. She imbued this gate into a sword made from her daughter’s fusing it with a portion of her daughter’s soul and granting it sentience. Iyo can manifest itself to those have the power of the .
Reiki is generally blamed for Shin Natsume's insanity and although the sword is typically considered evil by the characters, its spirit is not depicted as having malice. Reiki only makes awakening the power take less effort. Given the nature of the , this often left the wielder to fight with their own power.

Reiki's power, simply defined, is the same as the Amaterasu Dragon’s Gate, neutralization of power. This allows Reiki to consume large quantities of ki, and render those with Red Feather powers as nothing more than "dolls". However it still has many unusual traits and abilities outside of neutralization.
Reiki can only be activated by those with special powers, and has even awakened powers in some cases. When wielded by someone without special powers it is nothing more than a very long katana. If the wielder establishes a good enough relationship with Reiki, it can even be activated while the user is not in possession of it.
When activated the blade allows the user to control and regulate their power better. The sword gains a visible aura around it and emits a piercing "RIIIIIIII" sound. While activated the blade also becomes encircled with energy rings with kanji on them, strange symbols appear on the blade as well. While activated Reiki becomes more powerful, even if it can't cut the opponent, they can be burned by the energy it emits. When Reiki true blade is completely activated by the Dragon's Eye, it uses an excessive amount of ki and can wear out most users out in a short period of time. The true blade of reiki is insanely sharp and is covered by a gold casing that functions as its blade.
