First of all, I didn't expect that explanation for why Youko was never mentioned by the characters from the future.
Second of all, Asahi and Youko's daughter is too adorable even from just a couple frames.
Third of all... YIKES. This is easily the darkest ending to a chapter so far. There have been a lot of bait-and-switches so far in this manga (which I have been fine with since they all end up happy), but this one is going to take some work. I mean, this manga has to have a largely-all-around happy ending, right? RIGHT?
