Well, Ishida didn’t say what his new project is, but he did tease one of the characters — a boy named Mitsuki Shirota. Here is his Tweet:

“A very happy New Year. Although my greeting wasn’t ready at the end, I ended Tokyo Ghoul:re and it was one of the milestones in my life. I’m trying to do some work outside of manga in 2019, and I hope to even come up with an idea for a new work. Thank you again for this last year. (The picture is of a boy to be used in a project).”
What’s interesting is that Ishida is looking to expand beyond the manga industry — perhaps we’ll see Shirota in an original anime written by Ishida? What do you hope he works on?
