i totally forgot that asako had recognized something was up with hikaru all the way back in chapter 3 and only realized when i went back to look at a page from there.... love the foreshadowing sooo much. very interesting to me how theyre setting up asako and yuuko as parallels to hikaru and yoshiki
A few chapters ago Asa showed she had the sight when she said they shouldn't cross the railway that day. She probably knew the moment she saw the new "Hikaru" like the crazy grandma or that other older lady.
Some chapters ago, her friend said she has "good intuition" as she pointed out they shouldn't go through the haunted crossing, so I suppose she has a sense for the supernatural.
