Event Interference

Phenomenon Intervention (事象干渉) is an ability that is called "The Power of the God". It can change its target's state from "exist" to "not exist" and vice versa. If it cannot be determined if target actually "exists" or not, it is almost impossible to perform a Phenomenon Intervention. Since sudden disappearance of target would shock surrounding it people, their memories are altered.

Phenomenon Intervention can be undone by the Manifestation Demolition Blade: Kusanagi.

The Takamagahara System used an extortionate amount of Phenomenon Intervention during the Continuum Shift, using the scattershot event to pick-and-choose which timeline they favored when getting closer to the Azure; this stopped when Hades Izanami seized control over the AIs.

In BlazBlue: Chronophantasma, Izanami used Interventions to create conflicts. Amaterasu rewinded time to get rid of these conflicts, but it made her closer to the real world.

Certain characters are capable of resisting it to some extent, such as those that are outside of the logic, like Valkenhayn R. Hellsing, and to an even greater degree, those that wield the Power of Order, such as Hakumen and Jin Kisaragi. However, it does not include environmental alterations. Hazama also posses a certain level of resistance, as him being affected is proof that the Master Unit is considerably close.
