The Sealed Treasure Spear: Izayoi (封印宝槍・イザヨイ Fūin Hōsō: Izayoi) is a Legacy Weapon possessed by the Magick Association.

This spear-like weapon with two floating blades requires a special permission from the association before it can be used. It was given to Kuon Glamred Stroheim for detention of Drei, Sechs, and Acht of the Ten Sages.[1]

It has the ability to seal all of the magical abilities of its chosen target, turning a conjurer into an ordinary person. By releasing the power of the Izayoi, a special barrier is created that is impossible to escape from.

Its price of use is blindness.
