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 girlhood 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 lapins quartz and volcanic ash.

Demonic Abilities and Techniques

 * 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.


 * Unique Ability to Sever the Unversed: 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, thus making it the strongest weapon, so far, wielded by the Half-Demon Princesses.
