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, fully replacing its two air/water-related attacks that Setsuna had acquired during her childhood in Shiori's safe haven for fellow lost half-demons.

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.

Abilities and Techniques

 * 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 . 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.
 * Muretachi no Tsubame: She continues to utilize this air-based attack from her original naginata.
 * Senpū-jin: She continues to utilize the same attack her original naginata had.
 * At one point, she attacked with a fiery bird resembling a, from a distance during her third battle against Kirinmaru.
