ITS REAL
Riichiro Inagaki (Eyeshield 21 - Dr.Stone) just retweeted it.
In a tweet to someone asking about it he said "Oh, am I allowed to say this? Because people are anxious to know if it's real or not. If you don't mind, I'll tell you."
Kosei also seems to confirm its real but is unsure on later tweets (?).
Murata confirms its REAL and from Togashi himself.
Gon and Killua VA tweet about it
Oricon officially confirms it
