Last week, Sui Ishida made an announcement that he is working on a new excitement manga which is going to release on 16 October. This might surprise you a little, but his new manga is titled as Tokyo Ghoul:re.
"The legend has a beginning. If you bear witness to this beginning, it will be a moment you will never forget as long as you live!!"
After the dramatic and unsatisfactory ending every one was waiting for new series, basically Tokyo Ghoul:RE is a sequel of an original manga.
