Record Deletion

Record Deletion (記録抹消) is unique in that it is a  phenomenon that only occurs after another has ended. This phenomenon appears during the  Asu Random arcs.

Decription
The Record Deletion phenomenon automatically activates during the aftermath of a phenomenon that has ended. All people involved, including Heartseeds, will have all their memories regarding the phenomenon wiped clean. The Cultural Research Club is the only known group to resist this phenomenon, having managed to retain their memories for almost two years. Record Deletion typically kicks in a few weeks after a phenomenon has ended. During the early stages, the deletion process randomly causes the people involved to forget random things at random times. Eventually, this will become a complete, permanent memory wipe of everything that has anything to do with the supernatural phenomenons. A side effect of this process is the inability to hear the conversations of other students in the school, which Taichi and Inaba experienced. The affected can see the mouths of others move but are unable to decipher what they are saying.

Trivia

 * This is the only phenomenon that affects the Heartseeds in some way and is involuntary.
