Yukari no Tachikiri

Yukari no Tachikiri is a heavenly weapon that is set to appear in Hanyō no Yashahime. 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.

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

Once Tōtōsai arrives, he grabs the broken naginata and starts reforging it, fixing the shattered blade and enhancing the blade's cutting ability.

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: Totosai says that, contrary to Tenseiga's ability to do no harm whatsoever, this stronger bladed weapon can freely cut objects and living beings, whether bodily or immaterial, of any kind. This most useful and strong unique skill even applies to Destiny/Fate itself, which could indicate that the Yukari no Takichiri grants its rightful owner most of the positive and negative abilities of both the Tenseiga and Bakusaiga at her disposal.
