OVA which was released as a tie-in to the Kandagawa Jet Girls video game for PlayStation 4.

The year is 1580. Using an army of soldiers equipped with sophisticated weaponry, Nobunaga Oda is on the verge of ruling Japan with an iron fist. One of his enforcers is Ginnai Doma - a fallen samurai reborn into an indestructible killing machine. As Ginnai continues his killing spree on ninjas and those who oppose Nobunaga's rule, Shishimaru of the Iga Ninja - going against the Koga Ninja's plans - pursues a one-man vendetta to avenge the deaths of his comrades and kill the immortal warrior.

The special of the day is Variable Geo-a brutal battle between waitresses who serve up generous portions of energy blasts and vicious side orders of murderous martial artistry. For buffed beauties who make below-minimum wages, VG is the perfect way to make some fast cash. The victorious walk away with millions, and the defeated lose everything (namely, all their clothes). But this high-stakes sport has dark forces and dubious practices behind the fun and games. Lethal injections make steroids seem like vitamins. Instead of team prayer, there's demonic possession. Athletic sponsors are malevolent corporations with a more frightening agenda than increased market share. It's all just part of the game.

The planet Libertia was once known as “the planet of death”, until humanity built three giant mirrors and created what seemed like an ideal land. It is on this planet that Professor Grace and his granddaughter Alcia live peacefully… until their home is attacked by Guild soldiers looking for the professor and for Legaciam – a special Armor that can resist extreme heat, allowing it to go to areas where humans would not survive normally. Alcia, who was at the time piloting Legaciam in order to help her grandfather with the testing, manages to get away… barely. But the Guild is determined to get Legaciam by any means necessary…
