Yukari no Tachikiri

Yukari no Tachikiri is a heavenly/hellish demonic weapon that appears in the premiere of Hanyō no Yashahime’s ongoing second season. It was first mentioned by Tōtōsai, who had first referred to it as "the exalted blade" and "a naginata capable of severing things that cannot be severed". Once fully forged, it is a larger and sharper blade atop Setsuna's naginata, still keeping its first two attacks that Setsuna had used since her girlhood in Shiori's safe haven for fellow orphaned half-demons, which gifts given to young Setsuna by Jaken in the form of daggers; one of which was affixed to the Kanitusme no Tomoe and the other on her waist which she still carries in spite of her no longer needing it anymore.

History
When heading to the remains of Izayoi's mansion, Jaken alerted Tōtōsai about Rin weeping, and needing to get to her daughters immediately. The aged demon sword-smith stated that he was heading there anyway, but lamented that he may not witness the birth of the exalted blade in time.

Once Tōtōsai arrived, he grabs the broken naginata and starts reforging it, fixing the shattered blade and increasing the effectiveness of the sickle blade's cutting ability via the rare lapis quartz and Tōga's ashes.

Physical description
It bares the same base as the Kanemitsu no Tomoe with an alteration of the main blade. After they return to the modern era through the Windmill of Time, it has a strap, and a green cloth that covers the blade.

Powers and Abilities

 * Natural Demonic Energy Generation: An unnamed attack similar to the Wind Scar, Setsuna unleashes a wide burst of her strong demonic energies to eradicate dozens of mindlessly violent demons in one mighty swing. This is great enough to create a large crater in the ground and disperse any remaining demonic energies of different types and strengths that may still hiding in the surrounding area, just as Moroha can with her sacred arrow.
 * Infinite Cutting/Severing: Tōtōsai says that, contrary to Tenseiga's ability to do no harm whatsoever, this considerably stronger bladed weapon can freely cut objects and living beings, whether bodily or immaterial, of any kind. This very unique skill even applies to all kinds of fate, which she sensed in the threads of fate. Sometimes before cut the indestructible thread, her blade goes to red flame when is about a guardian deity as opposed to a human or demon. This making it the strongest weapon, so far, wielded by the Half-Demon Princess.
 * Access to Infinite Memories: As Mayonaka has been told, the thread of fate's color was gold and when Setsuna had touched it, she can see his and Oharu's memories. After seeing another thread of fate between Zero and the spirit of her grandfather Tōga that she saw him for the very first time, she touched it to feel it before cutting it, as she had to save their mother as Zero was going to commit with her staff. It was these memories that she had seen glimpses of her late paternal grandfather and late step-grandmother.
 * Demonic Energy Barrage: While they're fighting Meidomaru, since her twin sister Towa use the Zanseiken's Kyūyōkon to absorb his vast demonic energies, his small threads of fate are connected to the Windmill of Time her blade had turned to a blood-red as it had against the deity Mayonaka, since Meidomaru was the Guardian of the Windmill of Time and embodiment of the 's very wrath as she cut another indestructible thread, which was nullified by Moroha's recently enhanced sacred arrow.
 * Multiple threads finder: Inside the Grim Butterfly, Setsuna sensed the multiple colored threads of fate as she must find which one is Rion's, than back at Mount Musubi only one between her and her father Kirinmaru.
