Time Wave

'Time Wave' is a term coined by Stacey during the events of Time Crisis.

When a group of senior students sneaks onto the football field of the junior school to plant a pipe bomb, unaware of the iminent eruption of a time geyser in that location, the resulting explosion causes a cascading tachyon field, which, over the course of 36 hours erases 3/4 of the student body from existence. This phenomenon is described by Pipa as a "sort of wave", causing Stacey to nickname it "Time Wave."
