The devastating Siege of Anteiku begins as an army of heavily armed CCG investigators completely cordons off the district, launching a relentless assault against the coffee shop. The elderly Yoshimura bravely steps onto the front lines, transforming into the massive One-Eyed Owl to draw the investigators' fire and allow his staff to escape. Upon learning of the active slaughter, Kaneki rushes back to the ward, abandoning all tactical safety to rescue his surrogate family. He carves a bloody path through the CCG forces, eventually colliding with his ultimate human rival, Kotaro Amon, in an epic, heart-wrenching duel where both combatants push their respective weapons to the absolute limit.
