BULLBUSTER

A young engineer named Tetsurō Okino, who has developed the new robot Bullbuster, is transferred to Hato Industries, a company that exterminates harmful animals. There, the company and its president Kōji Tajima are up against a mysterious lifeform named "Kyojū." As a small business that is always finding itself short on money, Hato must always account for every expense, such as fuel and pilot labor. And, of course, missed shots are not tolerated. The company is always stuck between its ideals of Kyōju extermination and the reality of the economy.
