Centuries of Secrets (Re-Write of Why Now?)

Secrets add up over time and create a rift between people. How well do others react when learning about what you've kept hidden for so long? What if the only way to save the world is by revealing your deepest and darkest secrets or being locked up for eternity? What would you do to keep your secrets safe? And what would you do if you didn't have a choice?

This is a re-write of one of my old books. I originally wrote the book "Why Now?" when I was in middle school and don't really like it but I also feel bad for leaving it unfinished. So here is a new version of it.
Warning, some of the old plot points were thrown out due to not fitting in my current writing style. Also it has been a long time since I have watched the show so I might miss a few details.

Please remember that none of the characters in this story belong to me. All characters belong to Hidekaz Himaruya. Other than that the storyline is my own.
