ドミニオン

In a future Newport City so choked by bacterial pollution that people wear gas masks outdoors, the police fight crime with tanks. Leona Ozaki transfers into the Tank Police with Bonaparte, a mini-tank she built herself, and with her partner Al she goes to war on Buaku, a super criminal who specializes in bank robbery, and his android sidekicks, the Puma Sisters AnnaPuma and UniPuma. Squad leader Charles Brenten runs the unit with little regard for property or regulations. This four-part OVA is a prequel to Masamune Shirow's Dominion manga.
