Comment on Hold the future by Kaiser-969

It is really good one, it is about a group of kids that get together a form a group. Thy have a meeting point, a symbol or flag and they write a book they call the book of prophecies.
Time passes and they are grown up, then a mysterious group sect/appears using the same symbol they had as kids and the sect is making prophecies true. The leader of the sect is called Tomodachi (friend) and uses a mask so the kids (now grown up) reunite and try to discover who Tomodachi is. Is it one of them or someone close to them? why does he know about the book and the symbol? what are his true intentions?
