Kikujūmonji

is a sword wielded by the dog-hanyō Towa Higurashi. However, it is an imitation of the genuine katana as it had broken with ease. It was Towa's main weapon in the first season by infusing her own demonic energy into and projecting a blade of pure said energy from it to terminate her enemies at a distance. Since receiving the legendary cosmic sword Zanseiken, it is no longer used but is still carried in its sheathe on her back. At point, it was utilized when Towa had become fully demonic at the interference and urging of Zero.

Physical description
The Kikujūmonji originally brought by Towa is a plain looking uchigatana with a brass-colored circular tsuba (guard) and kashira (pommel), and a red tsuka (wrap). The blade seems to have no hamon (temper line) or hi (fuller). Following battle with Mistress Three-Eyes, it is currently broken a quarter of the way from the tsuba. Towa apparently has not kept the remainder of the blade.

Towa is later given what appears to be the real Kikujūmonji, which has the hamon and hi expected of a genuine blade.

History
Legend says it once belonged to the esteemed shogun. However, the one wielded by Towa Higurashi is revealed to be a mere replica given to the Higurashi family on loan from a museum.

Towa later receives from Riku what appears to be the real Kikujūmonji, recently stolen from Deputy Shogun Ogigayatsu, though it is quickly recovered by his retainers.

Upon acquiring the Zanseiken from Rion, Towa had stopped using the broken katana as her main weapon. Tōtōsai stated before that the sword she was wielding since she returned to the Feudal Era was incompatible with her demon energy. While Towa encounters Zero and Nanahoshi, and since she had the Eternity Bug, her demonic self was reawkened and reuslted in her utilizing the replica katana to put an end to Nanahoshi in one strike. She was even able to disperse Zero's relentless barrage of reddish orbs comprised of her immense demonic energy with ease.

Powers & Abilities
While the blade was merely normal steel, Towa can use her yōki to create a blade strong enough to impale Mistress Three-Eyes, whose skin was hard enough to break the blade.


 * Enhanced Slashing: As it is empowered by Towa's demonic energy, its ability to slice through solid objects is more effective
 * From the tip of her energy blade, Towa can unleash a powerful demonic energy wave in the form of a colossal blue-white dragon, just like her father had originally with Tōkijin, now with Tenseiga.
 * A variant of the technique used by Towa in her full demon form, Kirinmaru was the one whom gave it the name.
 * Creation of Demonic Energy Barrier: During the fight with Kirinmaru, Towa first erected the pale blue barrier to protect her dead twin sister Setsuna from the explosion made from Moroha and Towa's combined respective dragon-based attacks had collided with Kirinmaru. Again, this shield was erected to defend Towa from a gigantic rock demon in "Takechiyo's Request."

Trivia

 * The activation of the yōki blade is similar to a lightsaber from Star Wars.
 * The Tsuba (guard) is styled after the flower which the 'Kiku' from its name stands for.
