Tsubaki Mode Change: Uncanny Sword (椿のモード変化「妖刀」, Tsubaki no Mōdo Henkō "Yōtō"), also called Mode: Uncanny Sword (モード「妖刀」, Mōdo "Yōtō"; FUNimation "Enchanted Sword Mode"), is a technique that allows the demon weapon Tsubaki to transform into the Uncanny Sword.[1]
Description[]
This technique, allowing for the Uncanny Sword transformation, transform the weapon into a katana with a black blade and a bandage-wrapped hilt.[1] Possessing this transformation also allow for a Multi-Form weapon the power to control shadows in such a form as well as other weapon transformations.[2] Uniquely, this mode also changes the appearance of Tsubaki's soul within her weapon form, various black markings appearing around her body.[3]
In the anime, the Uncanny Sword's true form is expressed and can be unlocked. The sword takes the form of a completely red, bright glowing version of the original Uncanny Sword with a longer blade and gives the Meister a tremendous boost of power.This form is only attained after acceptance of the Will of Nakatsukasa, in which allows the full power and usage of the transformation (and therefore it's related techniques) without ill effect.
