**Poof**

*many Kansens of different Nations suddenly appeared in a Theatre followed by the Sirens.. who's being led by Observer Zero and Lastly META Kansen.*

"Huh.. this place.." *Nagato hummed in slight surprise but kept her composure.*

"What is the meaning of this.. I was busy with Something.." *Nagato META spoke up before being interrupted by a voice.*

"Welcome to the reaction room!"

"The reaction room huh?" *Observer Zero repeated the voice's words as they continue to listen.*

"You're going to react to.. well.." *The voice starts explaining they're going to react to new Kansen that certain Nations will commission in the future.*

"Interesting.. Test site Beta keeps getting stronger and Stronger by the day it seems.." *Empress III commented to herself.*

"I wonder which Kansen we're going to react to.. hopefully it's Eagle Union.." *Cleveland said with an eager smirk.*

"I also hope they're from the Iris.." *Richelieu said with a hint of hope as she prays.*

"Not only that.. you will be visited by two special people from the past!" *A bright light emerged from the theatre after the voice stated that as two familiar figures, a girl and a male in his 50s that Enterprise META and the Sirens seemed to recognize.*

"Magistor.." *Observer Zero looked at the man, Dr. Aoste, the creator of Sirens.*

"Ah.. it's nice to see you girls again.." *Aoste said with a smile.*

"Creator.." *META Enty looked at the girl who smiled back at her, this girl was Dr. Anzeel, the Creator of KAN-SEN and wisdom cube tech.*

*After formal greetings were exchanged the human duo (Dr. Aoste and Anzeel) were informed by the voice that they were reacting to future commissioned Kansen from the other timeline (to which the Sirens call Test site Beta).

"Hmm.. I wonder how far they have pushed with wisdom cube tech.." *Anzeel wondered.*

"Only watching the large screen may your answers be answered Anzeel." *Aoste responds to his colleague.*

"Let's begin!" *The voice said with eagerness.*
