Information
Takamagahara is a mysterious organization of three individuals. They are invisible beings, but they can cast humanoid shadows from chairs to the floor in a white room. They seem to have one mind and observe all of the possibilities of the timeline, guiding it toward some certain goal. It is implied that they are god-like but were actually created by humans. They apparently want to destroy the Amaterasu Unit as well, but seem to want to keep time looping to prevent the world from ever ending.

They had given Rachel Alucard the position of "Observer", and she violated the rules by activating the Tsukuyomi Unit at the end of BlazBlue: Calamity Trigger, so they let her leave the position. They seem to have released Terumi as some sort of catalyst, and supposedly have a safeguard to keep him in check, however, during the split second when Ragna did the impossible, they were distracted, and Terumi manages to infiltrate Takamagahara. He unleashes a magical virus created by Phantom on them, which puts them out of commission.

Saya finds and destroys the Amaterasu Unit and takes control of Takamagahara. She says that she has stopped time from looping, and shifted causality from "random" to "sequential". She says that she turned the world back to how it is meant to be, into a "World of Death" like the one she is part of, supposedly meaning that there will be no more looping/parallel timelines, and that when things end, they shall end permanently.
