Gatchaman: Red Impulse (Gatchaman: Red Impulse #4)

Kentaro, Oniishi, and Masaki infiltrate the never-before-seen winter country of Novva Rozza, where Galactor has placed his factories! The factories are building an Antiproton Capacitor, a device that collects antiprotons from the atmosphere to create a bomb capable of unleashing annihilation on a massive scale.

Novva Rozza is completely under Galactor's control, and the Red Impulse Squadron must face their intense anti-aircraft artillery! Even if they win, they'll still need to deal with Galactor’s annihilation device itself...
