Sign (しるし, Shirushi) is the one hundred fifty-seventh chapter of the manga Tokyo Ghoul:re.
Ken Kaneki awakens in what appears to be a shrine, surrounded by a vast ocean of water and rows of gates. Baffled, he wonders where Touka Kirishima is, and begins wandering throughout the halls of the shrine, confused. He slowly recalls having returned to the Goat headquarters and battling the CCG. With some struggle, he remembers having been defeated by Juuzou Suzuya, and having devoured the Oggai afterwards...however, he then remembers having been engulfed by something massive, and his memory fails him.
Kaneki panics as he wonders whether he's awake, asleep, or even dead; he runs outside and jumps into the water, wading but soon having to swim. As he swims through the gates, massive eyes underneath the surface of the water quietly watch him.
Being pushed back by the waves, he dives underwater, only to see countless corpses; horrified, he resurfaces. However, to his shock, he sees Rize Kamishiro sitting upon a pillar; she asks him where he's going, calling him a murderer.
- Kaneki's mental environment is based on Itsukushima Shrine, famous for its floating torii gates. The shrine is considered one of Japan's National Treasures, and listed as a UNESCO World Heritage Site.
