A man with nothing but a knife and a gun decides to take on an entire military machine for the sake of dead soldiers nobody else remembers. That simple, brutal commitment never wavers, and the show builds its entire weight around keeping that promise. Merowlink doesn't philosophize about his revenge or second-guess himself, he just moves forward through the wreckage, and the OVA respects that clarity enough to make you feel the cost of it. This is for viewers who want their revenge stories lean and honest, stripped of the self-doubt that modern anime wraps around everything.

A soldier sets out on a path of personal vengeance after the Hundred Years' War. Merowlink Ality is the only survivor of a squad that was sacrificed and made to take the blame for the embezzlement of military resources. Carrying his fallen comrades' dog tags, he vows to track down the corrupt officers who betrayed them, including the general who tried to have them killed. What sets him apart is his talent as an Armor Hunter. Rather than pilot a mecha himself, he brings enemy machines down on foot, using an outdated anti-armor rifle and his combat knife. Along the way he may also uncover the truth behind the scheme. The OVA is an action-driven mecha and sci-fi story set in the world of Armored Trooper Votoms.
