Description

The world is exactly the same as reality but the thing that is different is that everyone's memories are reseted to before Personality Exchange phenomenon. 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 the Personality Exchange phenomenon. The members must used clues left behind by themselves before going to the Isolation Dimension to remember the things they forgotten. All records of any thing happening after personality exchange that involves with anything to do with Heartseed or result of Heartseed phenomenons disappeared.
