Immortal Breaker (ability)

The Immortal Breaker is an ability of the Zero Weave: Izayoi and Gallia Sphyra: Outseal.

Information
The Zero Weave: Izayoi is capable of killing those outside of reason, which is one of the reasons it's known as an Anti-Observer Armament. Its utilization requires removal of its restraints, after which the user has to pierce the target with its blade. At that point death is placed in the target's mind.

This ability was used in the series on two characters. Firstly, it was used on Jin Kisaragi, but the Immortal Breaker was nullified by the Power of Order and the blade didn't pierce him. The second time, Hades: Izanami was stabbed by the Izayoi blade, but it didn't work, as Izanami is the death herself. In Chronophantasma, Tsubaki Yayoi was tasked with utilizing this ability against Rachel Alucard, at the request of Rachel herself, in case that Ragna the Bloodedge wasn't slain before his natural death.

Gallia Sphyra: Outseal is a Legacy Weapon designed by humans during the Prime Field War for use against Prime Field Units. As a result it was given the ability to slay immortals.

Mai Natsume used Outseal's Immortal Breaker ability in Variable Heart when fighting against Fuzzy, who was a vampire and thus immortal.
