Thank you so much for posting the article @OrpheusJoshua. I had to contribute and share the news of Sayaka Kanda's passing since it wasn't posted on the site until now.
Seeing this news made me shocked considering how talented she is as a singer and voice actress and I feel really sorry for her family right now.
Now she is the 6th Japanese voice actor from Kingdom Hearts III to pass away after Koji Tsujitani (Woody), Yuu Shimaka (Goofy), Makio Inoue (Master Eraqus), Keiji Fujiwara (Axel/Lea), and Genzo Wakayama (Ansem the Wise).
Rest in Peace, Kanda-san (Princess Anna of Arendelle).
