Earth's Defense Army

"Now, you're probably curious about the EDA."

Not only me, I could understand Yumiko but Yuko was also nodding at his sentence. Like us, she's also unaware of their existence. He has too many secrets that he will only reveal when needed.

"You're already aware of the Transcendent and Mortal Worlds, right? The truth is, Earth has an auxiliary World connected to us. You could say it's a subordinate World which was devoid of any invasion from the Dark World."

Haam.. This Principal keeps on dumping new information, eh? In any case. If the Earth has a subordinate world, why is it awakened while the Earth was still unawakened?

Ah. If my guess is correct, the Earth was awakened at some point in time, which could also explain our reincarnation. Something happened which turned it back to an unawakened state.
