Power Release: The Spear of Striking Death Flight (突き穿つ死翔の槍, Rikiton: Tsuki Ugatsu Shishou no Yari), is producible by Yūmei via the application of Power Release.
He wraps a polearm in Power Release chakra, of which gains the innate ability to absorb chakra it comes into contact with in order to enhance its overall lethality. It is designed to penetrate through any barrier and obstacle composed of chakra, as well as to empower itself with any chakra absorbed to further penetrate consecutive obstacles. While in mid flight, the polearm gains an incredible piercing capability, which were its lethality to be increased to a moderate extent by means of absorbing chakra en route, then it'd gain a more prominent anti-matter capability, and prove a tremendous threat to even the more formidable of physical barriers as well.
The form and damage caused come close to Lugh's Brionac, but the having the ability "No matter how many times it is dodged, it will strike the enemy" makes it a weapon closer in nature to Odin's Gungnir. This rendition surpasses the original Gungnir in power, and that out of all the spears he knows, it is the only one able to pierce more than one layer of Koyoichi's Rho Aias. The spear travels at mach two, and the farthest he has thrown it is forty kilometres.
