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 referred to it as "the exalted blade". 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 destiny/fate, which she sensed the, thus making it the strongest weapon, so far, wielded by the Half-Demon Princesses.
 * Infinite Memories: As Mayonaka has been told, the thread of fate's color is gold and when Setsuna touched it, she can see his and Oharu's memories.
 * Infinte Super Cutting: After that, her blade goes to red flame to cut the indestructible thread since he's a god.

Evolved/Greatly Enhanced Attacks
Demonic Attack/Technique Advancement & Enhancement: Possessing such supreme demonic strength and energies within it, it even can help further develop and strengthen the only two attacks/techniques that Setsuna used with her original naginata, thus evolving them both to incredibly powerful levels and increasing each technique's effectiveness inflicting greater physical damage and able to unexpectedly converge at different angles and directions at larger distance and speed than ever before.


 * Muretachi no Tsubame: This is the greatly strengthened and evolved version of her Scourge of Swallows attack from her one of the two tanto blades of her original naginata. It is much wider, stronger and leaves more physical destructive damage than ever before at strikes at longer distance and angles.
 * Senpū-jin: This is the greatly strengthened and evolved of her Cyclone Burst attack of her original naginata.
