Votoms: Complete Collection vol.4 [BBLA-9014]

In the Astragius Galaxy, the Gilgamesh and Balarant nations had until recently been locked in a century-old galactic war whose cause was long ago forgotten. Now, the war is ending and an uneasy truce has settled. The main weapon of the conflict is the common Armored Trooper, a mass-produced humanoid combat vehicle piloted by a single soldier. Both the Armored Troopers and their pilots are also known as VOTOMS (Vertical One-man Tank for Offense & Maneuvers). However, since Armored Troopers have extremely thin armor, and use a highly combustible liquid in their artificial muscle, their pilots have a very low chance of survival and are commonly referred to instead as "Bottoms", the lowest of the low ("Votoms" and "Bottoms" are written and pronounced the same way in Japanese).

The series follows a main character named Chirico Cuvie, a special forces Armored Trooper pilot and former member of the Red Shoulder Battalion, an elite force used by the Gilgamesh Confederation in its war against the Balarant Union. Chirico is suddenly transferred to a unit engaged in a suspicious mission, unaware that he is aiding in the theft of secrets from what appears to be his side. Chirico is betrayed and left behind to die, but he survives, is arrested by the Gilgamesh military as a traitor, and is tortured for information on their homeworld. He escapes, triggering a pursuit extending across the entire series, with Chirico hunted by the army and criminals alike as he seeks the truth behind the operation. He is especially driven to discover the truth of one of the objects he was assigned to retrieve in that operation: a mysterious and beautiful woman who would become his sole clue to unraveling the galactic conspiracy.
