...What? You mean...You're talking about Sanae-san's case? Well, true, their personalities are-
Donn
I suppose, it's something like the sound of a mosquito, some people hear it, some don't.Yes, I'm talking about you.Reisen Udongein Inaba.The problem is this sound's effect. "Those who have their heads switched, will fall asleep and change their personalities after hearing the sound"......and "those who were not affected by the switch, after hearing the sound, won't fall asleep or feel uneasy around ones who had their heads switched".Even after that sound echoed around, you have always felt uneasy towards our switching, have you not?You even talked with us about what kind of sound it was.There're many reasons why that sound didn't take effect, right?They retained their personalities, just like me and Sakuya-san.
