Translated from the official Tokyo Ghoul movie twitter (x):
Attendees who watch the Tokyo Ghoul movie in the first 3 weeks can receive a coaster drawn by Ishida Sui specifically for this occasion as a present. And in the first week, the ban on the full cast illustrations will be lifted! 6 different illustrations are available for Kaneki, Amon, Rize, Hide, Nishiki and Yomo!!
