So you were doing such research. Well, it's just a theory, though.That would mean so.Sensation, is it......Come to think of it, that girl...It was quite a long time ago, though. I don't have anything to do with it.AhPutting that aside, in other words, it means that sensations like habits or customs would be easy to remain?She said that she『can hear a sound』... That it's a pleasant sound...As for why they would lose those memories, even with our organization's research we still know nothing about it.Though it seems like the research was halted now...
