She will be missed, as she had a really powerful and amazing performance as Anna Nishikinomiya in Shimoneta and as Magical Sapphire in Fate/Kaleid. Most memorable for me was her role in the Hayate no Gotoku series, where she voiced Izumi (I was kind of rooting for her, alongside Hinagiku). You can find her full role list here.
The news is very sudden, as her last post in the blog was about celebrating her birthday.
We, the team at Sakura Index, offer our condolences to her family, friends and co-workers. You will be remembered, and your voice immortalized in your works.
