Creators of 'ONE PIECE', Eiichiro Oda, and 'NARUTO', Masashi Kishimoto both release responses upon learning of Akira Toriyama's passing:
Oda,
"It is too early.
The hole is too big. Sadness washes over me when I think that I will never see him again. I have admired him so much since I was a child...
May heaven be the joyous world just as you envisioned it."
Kishimoto,
"I just received the news of Sensei's passing. I feel a tremendous sense of loss, more than when Dragon Ball ended... I still don't know how to deal with this hole in my heart. I can't even read Dragon Ball, which I love...
I pray that Akira Toriyama-sensei may rest in peace."
