She’s been tweeting since the first season if I recall correctly. She did it for the second season 2 too.Is it the first season of SAO that Yuki paid so much attention on watching the series? It became quite a routine that she'd tweet about watching SAO live at midnight, Japan time (except some weekend that she had a schedule on the next day?), and gave a comment on some exciting episodes. (As I can remember... this recent cliffhanger-ending episode and that one with the sexual assault scene.)
I feel like the more she feels relating to the series, the better music she gives. Or maybe it's just me. (This hypothesis would be absolutely wrong if she already kept tweeting like this since the first season, but I haven't noticed.)
I wouldn't use tweets as a measure of how much she relates to a series. She's just plugging a show she worked on, she does it for everything she scores.So my guess isn't on point at all..lol.
