I was also devastated by this event...
I'll be honest, I'm not a huge fan or Kyoani, only watched two series from them (Munto and Nichiyou), but still, to think so many creative people lost their lives in such a way... I can't imagine the amount of effort they had to do to even get a job there, the nights and days drawing to accomplish their dreams... I just can't believe this happened...
My condolences to the family, friends and fans as well. 
Hope they can come through this...
