Hiromedia Co., Ltd.

When a research crew in deep space discovers the desolate ship "Green Planet" that warps into their area, they encounter Buzz, the commander and sole surivor of the ship. Being too incapacitated to make them aware of the situation of his ship, the research team will soon discover that they have found something far, far worse...

Geist (the main character) is MD-02, a Most Dangerous Soldier, genetically engineered to function as a killing machine, but every one of the MDS units went homicidally insane. As a result Geist was placed in suspended animation in a stasis pod orbiting the planet Jerra until it crashed several years later, awakening him and bringing him into another war on the planet.
