People who keep using gramps as an example of someone living a long life with a FLZ need to go back and re-read that arc. HIS GREAT GRAMPA COULDN'T SEE THEM FOR 70 YEARS.
@iamkiki It was his great grampa's FLZ kyouko, dark eve was alluding to the fact that she had a melt down while saying she hated gramps for turning down his first love for her and that eve will find herself in the same situation if she realizes Ibusuki is a girl.
@anon763 Again, when she first...
@sterven There have been several times where eve doing something caused Tarou to collapse. Also gramps spent most of his life not being able to see them and before that spent a good chunk of time completely ignoring his.
