Kiana: When I examined Imaginary Space with my Herrscher powers, this vague information relating to St. Freya always existed in the background, regardless of the direction in which I focused.
Tesla: It’s like… the cosmic microwave background.
Kiana: Cosmic microwave background? What’s that?
Tesla: Uh… Kiana, have you ever paid attention in class?
Nagamitsu: Now, now, Dr. Tesla, the cosmic microwave background isn’t something Valkyries learn in class.
Nagamitsu: Kiana, have you heard of the big bang theory?
Kiana: The theory of the universe emerging as a point and expanding to its current size over time?
Nagamitsu: Yes. And the cosmic microwave background is the first ray of light that the big bang emitted. Those lights instantly filled up the tiny universe when they were created…
Nagamitsu: So after the universe has blown up in size, they are ubiquitous, flying toward us from every direction, and flying into the ever-expanding depths of the universe.
Bronya: But in that case… Dr. Tesla, Miss Nagamitsu, are you guessing that St. Freya is among the first areas on Earth to be swallowed by Project STIGMA?
Nagamitsu: Yes. The use of “first” isn’t accurate, but like the cosmic microwave background we just mentioned…
Nagamitsu: It must’ve been involved when Project STIGMA began to influence the world on a larger scale. This is the sole reason for you to have sensed it in every direction.
Nagamitsu: Therefore… as long as we can find the first breakthrough, with the Herrscher of the Void’s powers on our side, we won’t have much of a problem reclaiming St. Freya.
Einstein: There’s more. Once we do that, we can make further use of its “cosmic microwave background” status in Project STIGMA, and turn it into a bridgehead of reclaiming our space.
