Jack: Chapter 7

Serving as the concluding piece of the single volume prequel, this installment settles the ghoul case that a teenage Taishi Fura has been chasing alongside the investigator Kishou Arima. Wandering off on his own, Taishi muses that Arima and his classmate Uruka Minami would suit each other, only for the savage Yamori to corner him.

Elsewhere, Minami throws herself at Arima, whose blade Yukimura 1/3 turns the assault aside. He lays out how he saw through her: a 22 centimeter footprint recovered from a hotel during the investigation matched no student except her. Minami confesses she sabotaged a fellow ghoul and deliberately let Sumiharu wound her, all so she could edge closer to Arima, and she reveals that she recruited an accomplice to deal with Fura while she handled the swordsman herself.

Convinced Arima is going too easy on her, Minami presses her attack harder and is run clean through by his twin swords, her kagune collapsing to pieces. Arima then wounds Yamori in the back, though the ghoul still manages to flee. Fura reels at the realization that Minami is Lantern, the attacker who maimed his friends Aki and Ryou. She coldly brands the young men as ungrateful and better off dead, which pushes Fura to defend them before driving Yukimura through her and ending her life.

With Minami dead, the CCG collects her remains and Arima transfers to a different ward, where he and Fura take up a fresh ghoul assignment together. A jump of twelve years shows Taishi risen to First Class Investigator over the 7th ward, while Arima, now Special Class, moves on to a separate case. Struck by how little his colleague seems to age, Fura heads home to spend time with his family. The chapter reached English readers on September 13, 2016.
