I had the same reaction. On December 18 she was found unconscious in the outer garden on the fourteenth floor of a hotel in Chuo Ward, Sapporo. Then she was taken to hospital in an unconscious state, during that time many people (including me) thought it was just an accident, however she didn't survive and died some time later. Now, the hakkaido police believe it wasn't an accident.
You will be missed, but your work will live on. Not only her work, but also in the hearts of all her fans. Rest In Peace little Sayaka. Thank you for all the hard work
