...Maybe! Their true purpose might be to conduct clinical research they can't do in the surface world!If that's the case, then the children were born somewhere else and were taken, but...... if they
were about 4 years old at the time... it would be strange for them to not know where they came from.their memories were wiped! You guys!...Are you really gonna say we were drugged again? I just told you nothing like that happened.Anyway, you said all the children lost their memories.Isn't that unusual? Something must've been done to them......They don't remember the details, but they're aware of being somewhere else before coming to the facility.It's unlikely they were born in the facility.In other words,Huh? Can they do that?They sell the strong children as assassins to Yakuza to dispose of the test subjects they're finished with and fund their research!Could it be?!The truth is somewhere else!lit. "The inner castle/core is somewhere else."What if your memories of being drugged... were erased by the drug...?!
