Thanks! Sad is what I was going for (sad seems to be what I go for a lot…) 😀
I think Haru was very careful to make sure she wouldn’t end up a ghost–there’s a reason why she was so surprisingly successful/got away with so much in life, and that’s because she was one of the most (if not, the most) powerful medium in Japan. Hikaru’s ability, while stronger than her grandfather’s hazy sight, was still passive and so there’s no guarantee that someone would be there to help her move on if she died.
She might have done a final ghostly goodbye, but she didn’t linger on for too long. Also, seeing as how she dies because of Kira, she wouldn’t want to stay around a shinigami (as human she didn’t like it, much less as a ghost.)
