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".

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.
