Parallel World

The Parallel World (パラレルウールド) is an unnamed phenomenon that Inaba dubbed as such. This is the final phenomenon Heartseed forced upon the StuCS and was featured in Asu Random II.

Description
The Parallel World is a phenomenon Heartseed created because he was curious about how the StuCS would react if Record Deletion actually succeeded and the members had their memories wiped. The world is exactly the same as reality but the key difference is that anything relevant to the phenomenons has been erased from the StuCS's memories and everyone continued living as if those events never transpired. This phenomenon is a "what if" scenario Heartseed wanted to see. The phenomenon is over once the StuCS members remember everything that has happened after meeting Heartseed. The members must use clues left behind by themselves before going to the Isolation Dimension to remember what has been forgotten.

Trivia

 * This is the only phenomenon which Heartseed doesn't explain to the StuCS and no exact name given.
