Manus Jaldae

Manus Jaldae (Hands of Ialda) is the ninth spell learned by Negi Springfield during his childhood. It is a High Ancient spell capable of killing normally unkillable beings such as the demon Willhem and the Lifemaker. Negi Springfield theorizes that the spell was created by the Lifemaker.

The spell was first mentioned by Wilhelm following his defeat at Negi's hands however it was not used at the time. In the UQ Holder! timeline (Second timeline where Asuna Kagurazaka felt asleep for 130 years), Negi Springfield plans to use the spell to defeat the Lifemaker by being possessed and then activating the spell within himself to destroy it.

Later in the UQ Holder! timeline Evangeline A.K. McDowell proposes using it herself to defeat the Lifemaker as an alternative to the Negi Springfield Cloning Project.
