Mobile suit Gundam Thunderbolt. Vol. 5 - Yasuo Ohtagaki

In the Universal Century year 0079, the space colony known as Side 3 proclaims independence as the Principality of Zeon and declares war on the Earth Federation. One year later, they are locked in a fierce battle for the Thunderbolt Sector, an area of space scarred by the wreckage of destroyed colonies. On Earth, political turmoil has led the Nanyang Alliance to challenge Federation control. Now in possession of Zeon's priceless Reuse P Device technology, the Alliance moves forward with its plans. If they can develop the stolen tech, it could make them invincible. Both Io Fleming and Daryl Lorenz begin new operations against the Alliance on dangerous missions that are sure to bring them face-to-face once again.
