Sealed Armament: Izayoi

The Sealed Weapon Izayoi is the weapon of choice for Tsubaki Yayoi in BlazBlue: Continuum Shift. The Izayoi is kept under a special lock that can only be opened from the blood of a person from the Yayoi Family. Tsubaki needed the Izayoi to combat both Jin Kisaragi and Noel Vermillion since they both posses Nox Nyctores class weapons. The Izayoi takes the shape of a dagger-like weapon and a book-like shield. However, it can change its shape for some of Tsubaki attacks. The Izayoi has a negative side-effect, as it allows its owner to control light, it steals the light from the user's eyes. Due to this, using the weapon for an extended period of time will cause the user to go blind. The fact that it causes people to go blind during the course of Continuum Shift is told in both Story and Arcade Mode. As a matter of fact, Tsubaki is told numerous times to get rid of it. It is also revealed in Tager's "Help Me, Professor Kokonoe" that along with it's wielder's light, it can steal all types of light including a wavelength for electo-magnetic equipment or in Tager's case, his radio.
