Tokyo Ghoul: Past(2014)

Tokyo Ghoul: Sekijitsu

Before the steel frame incident in the 20th Ward, there were reports of Ghouls lurking among the masses in Tokyo, carefully stalking their prey. This novel covers the events that occurred before the opening act of Tokyo Ghoul—a time when Kaneki was still human, the Kirishimas still lived together, and Rize enjoyed her feasts.
