Bullet Train Explosion

Hayabusa 60 (5060B) is an E5 Series Shinkansen bound from Shin-Aomori to Tokyo, under the supervision of first-line manager Kazuya Takaichi. Shortly after the train's departure, an anonymous caller contacts the JR East headquarters in Tokyo, saying they have planted a bomb on the train that will explode if it slows down below 100 km/h. After the bomber proves their claim with the destruction of freight train 2074 at Aomori-Higashi, JR East orders all trains on the Tōhoku Shinkansen stopped to clear a path for Hayabusa 60, whose driver Chika Matsumoto is ordered to pass through all stations and stay above 120 km/h, while keeping the bomb a secret to the passengers.
