10

On Christmas Eve, Kanuka’s grandmother disappears, leaving a note about seeking the Christmas of fifty years ago. Noa, Asuma, and Kanuka search for her but are recalled to SV2 duty. Detective Matsui requests assistance as vehicles vanish inside the Tokyo Port Tunnel without returning, and communications are disrupted. Although the military is already mobilized, Matsui urges SV2 action. Division 1 enters the zone but fails to contact Division 2. Noa and Ohta enter the tunnel to find only the wreckage of Division 1’s Labors, with no crew visible. Suddenly, Shaft Broken Labors surround Division 2 and launch an attack.
