This will have to be brief since I'm about to leave for Otakon. Basically, she's a rabid and wanky Rin/Haru shipper, and despite the way she waves living in Japan as proof of authenticity, she tramples all over the local fandom mores with her doujinshi scanlations. And she's horrible about bashing competing ships. I only really noticed her in Free! because someone I follow reblogs her a lot, but people on FFA have said that she did similar things in Project K as well. I don't really have concrete examples, right now, because picking through active tumblrs is a misery I don't have time for.
