Enrakyōten (Seireitou)

Enrakyōten (艶羅鏡典, "Law of the Bewitching Lucid Mirror") is the  entrusted to the  of. According to, the sword is the family treasure of the clan and was meant to watch over the history of. It was briefly wielded by Tokinada Tsunayashiro, but following his death, the fate of the sword is unknown.

Powers
Curse: Like all held by the, Enrakyōten is also a cursed sword which indiscriminately drains away the  from its wielder at a steady pace until the owner either relinquishes the sword or they die. Therefore, it can only be wielded by an individual with a strong enough reiatsu that can stave off the curse long enough to make effective use of the blade.

Partial Release: It is possible for Enrakyōten to be partially released by sealing it with a false name. When it was wielded by Tokinada Tsunayashiro, he had sealed it under the name 'Kuten Kyōkoku' (九天鏡谷, "Nine Heavens Mirror Valley"); a name chosen due to resembling the name of, which Tokinada did intentionally to mock. The command release for its false seal was "Venerate".


 * Attack Reflection: When it is called by a false name, the power of Enrakyōten is halved, and only allows for what appears to be the total reflection of an opponent's attacks. In a sense, it acts like a mirror and deflects any attack that comes into contact with it; comparable with the ability of.

True Release: In order to release the true form of Enrakyōten, the release command "Sip from the four seas, the heavenly shores entwine. Equally duplicate ten thousands, and sharpen." must be spoken followed by its name. Upon being released, a bright flash of light envelops the vicinity of the wielder. When in its true form, the blade of the Zanpakutō does not possess a visible form, and is said to emit a sinister reiatsu.


 * Zanpakutō Mimicry: Enrakyōten's true power is to freely imitate the powers of any the wielder has either observed or possesses knowledge of through indirect mediums. The sword, therefore, serves as a representation of the Tsunayashiro family and their role as the keepers of history within the Soul Society. In truth, however, this is not an accurate depiction of what it can do. When Enrakyōten was first forged, it was bestowed with the ability to assume the powers of anything that takes on the name and form of 'blade'. If it can be imagined as a blade, regardless of its properties, then it can be copied by the Enrakyōten. Therefore, it is not solely limited to Zanpakutō, but can imitate the abilities of any weapon even remotely similar or related to that of a sword. What limits Enrakyōten's imitative powers is the degree of reiatsu its wielder possesses as well as its nature. Pure  would be incapable of imitating, due to lacking  reiatsu, and similarly, trying to imitate the weapon linked to somebody with multiple natures that the wielder themselves lack would only result in an empty shell of a mimicry. For instance, when Tokinada attempted to imitate , the Zanpakutō of , he could only imitate its shape and the sword itself was brittle enough that it could be easily shattered. Originally, Enrakyōten was created for the purpose of copying the powers of the sealed Amenomusuha, but it was deemed impossible for any individual to manage it without suffering total soul suicide.
